A kind of moisture-proof high air-permeability non-woven wallpaper and its preparation method
The invention discloses a piece of moisture-proof highly-breathable non-woven wallpaper and a preparation method thereof. The method comprises the following steps: respectively placing waste fibers, plant fibers and chemical fibers into a first stock chest, a second stock chest and a third stock chest; adding a packing, a sizing agent and a wet strength agent; forming a non-woven wallpaper upper layer through the plant fibers; respectively placing mixed solutions in the three stock chests into fluffers to be defibered, respectively adding a retention aid into the stock chests filled with the mixed stock after defibering, uniformly stirring the mixtures, and then adopting the inclined wire processing technology to achieve layered stock intake; respectively feeding the three layers of stock into flow boxes, subjecting the stock to water filtration and retention on a forming wire to form a wet paper web, drying to obtain an upper layer of body paper, an intermediate layer of body paper and a lower layer of body paper, which are different from one another, coating paste starch among the body paper, adding a flame retardant, and then drying to obtain the moisture-proof highly-breathable non-woven wallpaper. The non-woven wallpaper has favorable air permeability, moisture resistance and fungus resistance, and is good in stability, resistant to impact, free of deformation and excellent in coverage.

Manufacturing method of highly corrosion-resistant/mildew-proof bamboo scrimber
ActiveCN114800745AImproved anti-mold and anti-corrosion effectExtended service lifeFlat articlesDomestic articlesFiberAsphalt
The invention discloses a high-corrosion-resistance / mildew-proof bamboo scrimber manufacturing method which comprises the steps that dried defibered bamboo bundles are soaked in heat conduction oil in which asphalt is dissolved, and the defibered bamboo bundles are taken out and drained to obtain pretreated defibered bamboo bundles; mixing the asphalt powder with an antioxidant, adding the crushed bamboo fiber, and uniformly mixing to obtain an asphalt and bamboo fiber mixture; alternately paving a mixture of pretreated defibered bamboo bundles and asphalt bamboo fibers in a cold pressing mold, pressing to a preset thickness according to the length and width size of the mold and the target density of the plate blank, and fixing by using an iron plate and a screw to obtain a bamboo recombined square timber plate blank; and the cold pressing die bearing the bamboo recombined square timber plate blank is placed on a sample frame, heating, cooling, leveling, permeating and gluing treatment is carried out, the sample frame rotates regularly during the period, unloading is carried out after 5-10 times of circulation, finally, surface treatment is carried out, and the high-corrosion-resistance / mildew-proof bamboo recombined timber is obtained. The prepared bamboo scrimber has the advantages of being high in hydrophobicity, high in corrosion resistance / mildew resistance, resistant to loss of functional components and the like, and is suitable for outdoor garden landscape engineering.

A kind of viscoelastic anti-mildew and anti-corrosion glue and tape for buried pipeline and preparation method thereof
ActiveCN104327756BAvoid erosionEnhanced inhibitory effectNon-macromolecular adhesive additivesFilm/foil adhesivesAntioxidantPlasticizer
The invention discloses a viscoelastic body anti-mildew and anticorrosion adhesive for buried pipelines, an adhesive tape and a preparation method thereof, and belongs to the technical field of pipeline anticorrosion. The viscoelastic body anti-mildew and anticorrosion adhesive is composed of the following components, by weight, 100-300 parts of a polymer viscous-elastic material, 1-10 parts of enhancing glue, 100-300 parts of a filling material, 1-10 parts of an antioxidant, 1-10 parts of a plasticizer, 1-5 parts of a mildew preventive and 0.1-0.5 part of a pigment. By adding the mildew preventive in the viscoelastic body anti-mildew and anticorrosion adhesive, erosion of mildew can effectively be prevented, and shear strength and volume resistivity of the adhesive layer can be enhanced by cooperation with other components in the formula. Thus, the adhesive's peel strength of a steel or PE material is raised, and mechanical property of the adhesive layer is improved. By the use of the adhesive, buried pipelines made of different materials can be glued well. The adhesive has a good effect of inhibiting common mildews such as aspergillus flavus, aspergillus niger, aspergillus sydowi, aspergillus terreus, aspergillus ustus, Penicilnum chysogenum, Cladosporium, cheatomium, trichoderma and the like.
