摘要： The present application discloses a fireproof coating material, and belongs to the technical field of fireproof coatings. The fireproof coating material includes 40-80 parts of an aqueous curing agent, 20-50 parts of water and 80-200 parts of a mother liquor of the fireproof coating material, wherein the mother liquor of the fireproof coating material consists of 50-80 parts of a flame retardant, 15-25 parts of a dispersant and 190-220 parts of water. The flame retardant used can not only effectively improve the problems of poor compatibility and mixing uniformity of a flame retardant with an aqueous latex in the existing fireproof coating material, but also can utilize O and H contained in a flame retardant system to form a carbonized layer during dehydration to isolate oxygen, preventing combustion, and enhancing the fire retardant performance.

摘要： The present disclosure is direct to titanium dioxide-containing, polycarbonate-based thermoplastic compositions that contain epoxidized triacylglycerol. These compositions are suitable for reflectors. The compositions described in the present disclosure have an improved reflectance and a lower yellowness index as compared to reference compositions that do not contain epoxidized triacylglycerol. The epoxidized triacylglycerol may be in the form of epoxidized soybean oil.

摘要： The present invention relates to an epoxy resin composition for a copper clad laminate, and an application of the epoxy resin composition. The epoxy resin composition may be used for the preparation of pre-pregs and copper clad laminates. By using brominated epoxy resin such as a low bromine epoxy resin and a high bromine epoxy resin as bromine sources and taking a phosphorus-containing phenanthrene-type compound as a phosphorus source, and adjusting the proportions of the brominated epoxy resins and the phosphorus-containing phenanthrene-type compound within the epoxy resin composition, the bromine content is controlled at 5-12%, the phosphorus content is controlled at 0.2-1.5%, and the flame retardancy achieves the level of UL94 V-0. Compared to pure bromine flame retardant copper clad laminates, the heat resistance is higher, and a higher CTI value is achieved. Compared to pure phosphorus flame retardant copper clad laminates, the moisture absorption is low, and the adhesion performance and process operability required for printed circuit substrates are provided. Compared to the use of a large amount of aluminum hydroxide in traditional high CTI sheet material, the present invention achieves CTI>600V using a small amount of aluminum hydroxide or without using aluminium hydroxide.

摘要： A fluororubber tube is provided, which is formed from a rubber composition containing a fluororubber, and not less than 3.8 parts by mass and not greater than 4.1 parts by mass of a polyol crosslinking agent and not less than 3 parts by mass and not greater than 7 parts by mass of a carbon black based on 100 parts by mass of the fluororubber. Thus, the fluororubber tube is made less tacky by suppressing the intrinsic adhesiveness of the crosslinked fluororubber without formation of a coating film which may otherwise complicate the structure of the tube and the production process of the tube or may result in contamination.
