    摘要: A millable polyurethane rubber, preparation method and use thereof. Raw materials thereof comprise the following ingredients in part by weight: polyester diol 100 parts; micromolecular diol 2-10 parts; diisocyanate 5-20 parts; antioxidant 0.1-0.5 part; catalyst 0.03-0.08 part; peroxide 1-1.5 parts and/or sulfur 1-1.5 parts. By structural design and formula adjustment, the millable polyurethane rubber has better low temperature resistance and gas permeability compared with conventional millable polyurethane rubbers, by using special micromolecular diol, synthesizing with polyester diol at a specific ratio and vulcanizing with peroxide or sulfur, molecular strands of the polyurethane have excellent smoothness and strong interaction forces, the millable polyurethane rubber has at the same time characteristics such as time good low temperature compression set, low gas permeability and high mechanical strength and can be used in manufacturing of films in scuba suspension systems.

    摘要: The invention relates to a water based paint composition to be used in a pressurized and sealed aerosol can and which composition contains A) up to 24% w/w of propellant gas which is dimethyl ether (DME); B) up to 76% w/w of coating material, consisting nonvolatile content in the range of 65-95% w/w and volatile content in the range of 5-35% w/w; —which volatile content contains water up to 0-100% w/w and additives, co-solvents and dispersing agents which comprise altogether of 0-9% w/w of volatile liquids, having 0-10% w/w preferably less than 5% w/w of volatile organic compounds (VOC) provided that the aggregate amount of dimethyl ether (DME) and the volatile organic compounds (VOC) in volatile liquids is such that VOC concentration is below 186 g/l (responding about 24% w/w, calculated as DME). In the present invention the nonvolatile content comprises color pigments and possible fillers in the range of 0-30% w/w, polyurethane modified alkyd resin or alkyd resin in the range of 25-99% w/w preferably in the range of 35-90% w/w and additives up to 9% w/w, which resin is present as an emulsified dispersion in water miscible solvent comprising water and dimethyl ether (DME).
