Provided is an oil-in-water emulsion-type hair cosmetic which is highly compatible with the hair and easily spreadable thereon, does not fall in drops in using, and has a transparent or translucent and beautiful gel-like appearance while having a rich texture and exerting a high repairing effect comparable to oil-based hair-care products. The oil-in-water emulsion-type hair cosmetic, comprises: (a) 0.1 to 10 mass% of a silicone compound selected from among a high-molecular silicone having a gummy nature or a viscosity of 1,000,000 cs or higher, a silicone hydroxyl-modified at both ends, an amino-modified silicone, an ammonium-modified silicone and a polyalkylene glycol-modified silicone; (b) 0.5 to 79 mass% of dimethylpolysiloxane having a viscosity of 100 cs or lower; (c) 1 to 25 mass% of a polyhydric alcohol; and (d) 1 to 10 mass% of a hydrophilic surfactant, wherein the content of the oily phase is 50-80 mass%, and the composition ratio by mass of (a) to (b) is 1:100 to 1:5.

The invention provides a tobacco stalk expansion method, which comprises the following steps of: grading tobacco stalks, performing impregnation remoistening on the graded tobacco stalks and expanding the tobacco stalks, wherein a microwave heating expansion method is adopted in the expansion of the tobacco stalks; preferably, the microwave heating expansion is performed on the tobacco stalks under a vacuum condition; more preferably, the microwave heating expansion is performed on the tobacco stalks by adopting more than two different kinds of continuous microwave output power under the vacuum condition, wherein the former two kinds of continuous microwave output power are 4.0 to 8.0 kw and 1.5 to 2.5 kw respectively for every kilogram of remoistened tobacco stalks; and the impregnation remoistening comprises the steps of: spraying water onto the tobacco stalks, and performing the impregnation remoistening under the pressure of 0.112 to 0.203 MPa and at the temperature of 50 to 100 DEG C. The expanded tobacco stalk has the characteristics of greater volume that is 1 to 3 times that of the conventional tobacco stalk, uniform expansion, remarkable fragrance, less wood smell, high resilience, the water content of 0.5 to 3 percent, high combustibility, improved intrinsic quality and relatively better smoke characteristic maintenance.

The invention belongs to the field of coatings, and particularly relates to an aqueous exterior wall coating with temperature control mildew resistance and a preparation method of the coating. The coating comprises the following components: an isopropyl acrylamide modified acrylate emulsion, an organosilicone modified acrylate emulsion, isothiazolinone, lightweight calcium carbonate, talc powder,a dispersing agent, a levelling agent and deionized water, wherein the isopropyl acrylamide modified acrylate emulsion is prepared from the following components: N-isopropyl acrylamide, butyl acrylate, acrylic acid, allyloxypropyl alkyl phenol polyether, a dialkyl sulfosuccinate salt of allyl, ammonium persulfate and deionized water. The coating provided by the invention is a novel exterior wall anti-mildew coating capable of controlling a release speed of an anti-mildew agent at different temperatures, has high mildew resistance, good weather resistance, light and thermal stability, chemicalstability, stain resistance, wash resistance, corrosion resistance and self-cleaning performance, and also has gloss and fullness. The invention also provides the preparation method of the coating.

The invention provides a preparation method of an acrylic-resin-modified water-based nitrocellulose emulsion for paint, which comprises the following steps: in an oxygen-free environment, reacting dehydrated dibutyltin dilaurate, isophorone diisocyanate tripolymer and N-methylpyrrolidone dissolved dimethylolpropionic acid at 40-45 DEG C for 1 hour, adding butanone dissolved nitrocellulose at 72 DEG C to react for 2 hours, cooling to 40 DEG C, regulating the pH value of the reaction solution to 8-9, cooling to room temperature, and adding water into the reaction solution while stirring uniformly to obtain a water-based nitrocellulose emulsion; and physically mixing the water-based acrylic emulsion and water-based nitrocellulose emulsion at room temperature to obtain the acrylic-resin-modified water-based nitrocellulose emulsion for paint. The preparation technique is simple; and the prepared acrylic-resin-modified water-based nitrocellulose emulsion for paint has the advantages of high stability, high flexibility, high adhesive force, certain fullness, yellowing resistance, water resistance and no pollution.

The invention relates to a chemical technology field, concretely, discloses high-hardness white unsaturated polyester priming paint and a preparation method thereof. The priming paint contains a first component, cobalt isocaprylate (blue wate), methylethyl ketone peroxide (white water), and a diluent, wherein the weight ratio of the first component, to cobalt isocaprylate (blue wate), to methylethyl ketone peroxide (white water) and to diluent is 100:(0.8-2):(1-2.5):(30-40). The high-hardness white unsaturated polyester priming paint and the preparation method resolve the problem that the PU polyurethane paint has bad hardness, the usage of unsaturated polyester paint reduces the VOC content of the paint, and the high-hardness white unsaturated polyester priming paint has good fullness and filling effect.

The invention provides waterborne tall oil alkyd resin emulsion and a preparation method thereof. Waterborne alkyd resin is prepared by taking tall oil extracted from papermaking waste liquid as a raw material; a preparation process comprises: (1) taking the tall oil to react with diethanolamine to prepare tall oil diethanolamide; (2) preparing a polyester intermediate by taking the tall oil diethanolamide and dibasic acid with a sulfonic group to react with dihydric alcohol; (3) taking the polyester intermediate, vegetable oil, fatty acid, polyatomic alcohol and polybasic acid to react and adding de-ionized water and dispersing to prepare alkyd resin water dispersoid. The tall oil extracted from the papermaking waste liquid is effectively utilized, and an application range of the tall oil is also expanded.

The present invention provides fabrics with high density, fullness and softness. It is possible to provide a highly heat-shrinkable polyamide fiber with a glass transition temperature (Tg) of 85-95°C, a boiling water shrinkage rate (B) of 30-50%, and a heat-shrinkage stress (H) of 0.20 cN / dtex or more.
