When being applied to surface protective paper, the aqueous pressure-sensitive adhesive provided by the invention is capable of protecting surfaces of products, such as acrylic plates, polycarbonate plastic plates, polystyrene plates, polyvinyl chloride plates, glass, marble and wood furniture decorative plates, under the ultra-low peeling strength, and avoiding the conditions, such as foaming, edge warping, and residual after tearing.

The invention relates to a viscose glue and a viscose glue plaster prepared from the viscose glue, wherein the viscose glue is capable of realizing non-trace adhesion and being repeatedly used for multiple times. The main components of the viscose glue include silica gel and a tackifier, the silica gel weight accounts for 40%-60% of the overall weight of the viscose glue, and the tackifier weight accounts for 40%-60% of the overall weight of the viscose glue. The viscose glue has high activity groups, and when in use, the viscose glue can fill gaps on the glued material surface to exclude air inside the gaps so as to enable the viscose glue to attach to the glued material surface. The viscose glue mainly depends on adsorption type adhesive force for attaching, so that the viscose glue is convenient to tear off, and no residual excess viscose glue may be left on an attached material. The viscose glue plaster prepared from the viscose glue, which has a certain pattern, can be widely applied to sticky hooks, hanging pasters, electronic product pasting films and other various home furnishing, advertising and printing products, and has a great applicable range and market prospect.

The invention belongs to the technical field water-proof materials of buildings and particularly discloses a tear-free self-adhesive rubber waterstop belt and a preparation method of the tear-free self-adhesive rubber waterstop belt. The invention adopts the major technical scheme that the rubber waterstop belt comprises a rubber base material, as well as a high polymer self-adhesive layer and an isolation layer that are pasted on one side face of the base material. The rubber base material is prepared from natural rubber, ZnO, stearic acid, an antiager, a reinforcing agent, operating oil, functional filling and a valcanizer via an extrusion technology, the high polymer self-adhesive layer is formed by melting SBS (styrene-butadiene-styrene) or / and SIS (styrene isoprene styrene) resin softening oil, an antiager, an reinforcing agent, operating oil, functional filling and an antioxidant via a stirrer, and the isolation layer is formed by stirring and mixing natural zeolite, metakaolin, wollastonite and stearic acid, and then the prepared high polymer self-adhesive layer and the isolation layer are applied on the rubber base material for calendering to form the belt. The waterstop belt has the self-adhesive layer which is securely connected with a concrete boundary layer, greatly improves adhesion between the rubber waterstop belt and concrete, and effectively solves the problems of water leakage and dampening of an expansion joint, a deformation joint and a construction joint.

The invention relates to an adhesive sticker for bonding rubber products. The adhesive sticker mainly comprises 100 parts of rubber, 5-20 parts of tackfying resin, 2-5 parts of accelerating agent, 5-10 parts of activating agent and a right amount of solvent. The adhesive sticker does not contain a vulcanized agent, can be stored for long term and can be used for conveniently and firmly bonding the rubber products. The invention also relates to a rubber type non-drying tape containing the adhesive sticker.

The invention provides a hydroxyl coumarone resin and preparation method thereof, and belongs to the field of resin preparation. The hydroxyl coumarone resin is prepared from a polymerizable component-containing mixture and 4-hydroxystyrene or 4-hydroxyl methyl cinnamate or 4-hydroxyl ethyl cinnamate, and the polymerizable component-containing mixture is obtained through distilling a heavy benzene fraction of coal tar; and polymerizable components comprise indene and coumarone, and the mass of 4-hydroxystyrene or 4-hydroxyl methyl cinnamate or 4-hydroxyl ethyl cinnamate is 1-20% of the mass of the polymerizable components. The hydroxyl coumarone resin contains hydroxyl groups, so the hydroxyl value of coumarone resin is substantially improved, and the coumarone resin has good compatibility with polar resins; and the coumarone resin carrying the hydroxyl groups chemically reacts with other components to form interpenetrating network crosslinking, so the performances of coatings and adhesives are further improved.

The invention discloses a preparation method of a natural rubber pressure sensitive adhesive, and belongs to the field of chemical industry. The natural rubber pressure sensitive adhesive is prepared by taking natural rubber, butyl rubber, polysulfide rubber, a mixture of benzene and solvent gasoline, coumarone resin, dioctyl phthalate, lanolin, alumina powder and anti-aging agent RD as raw materials and using a chemical reaction kettle as a reaction container based on proper temperature and a proper reaction duration. The preparation method disclosed by the invention has the advantages of simple production process and general purpose of the adopted equipment; the product is good in permanent adhesion, excellent in low-temperature performance, rapid in adhesion and good in adhesive force, and the shortcoming of poor aging resistance is greatly improved by the addition of a modified rubber.

The invention discloses an oil-resistant silicone rubber sealant, which is characterized in that the mass ratio of its raw material components is: 30-50 parts of silicone rubber, 20-50 parts of fluororubber, 10-15 parts of tackifier, filler 10‑20 parts, 10‑20 parts of calcium stearate, 1‑10 parts of vinyl tributylketoxime silane, 2‑5 parts of white carbon black, 1‑3 parts of epoxy soybean oil, 0.5‑3 parts of vulcanizing agent . The oil-resistant rubber sealant of the invention has good heat resistance and low temperature resistance, oil resistance and chemical resistance, and has the advantages of reduced elongation at break.

The invention relates to a kind of matting without warps. The matting comprises a matting body. Bamboo battens are used as the wefts of the matting, and the adhesive tape is used for replacing warps to bond the bamboo battens so that the matting body can be formed. The adhesive tape is composed of base materials and adhesive. The adhesive is prepared from, by weight, 10 parts to 20 parts of modified SBS resin, 15 parts to 40 parts of tackifying resin, 50 parts to 100 parts of solvent, 1 part to 3 parts of plasticizer, 5 parts to 8 parts of filler, 0.5 part to 1 part of anti-aging agent and 0.5 part to 1 part of antioxidant. According to the processing technology of the matting, first, the bamboo battens are used as the wefts, the bamboo battens are hot-pressed together with the adhesive tape at the temperature from 30 DEG C to 60 DEG C under the pressure from 2 MPa to 6 MPa, and the matting body is obtained; then, the fracture surface of the matting body is wrapped with edge lining cloth, compaction is performed, edge covering is performed, and the matting without warps is made. Only the wefts rather than warps of the matting can be seen from the front face of the matting, and the matting has a distinctive visual effect, and is good in firmness and long in service life.
