The invention discloses a novel flame-retardant cable material. The cable material is prepared from raw materials in parts by weight as follows: 15-35 parts of polyvinyl chloride, 3-8 parts of an ethylene-octylene copolymer, 13-18 parts of ethylene-vinyl acetate, 18-33 parts of high impact polypropylene, 7-18 parts of nitrile rubber, 1-2 parts of stearic acid, 12-23 parts of filler, 1.5-3.3 parts of a heat stabilizer, 0.7-1.2 parts of an antioxidant, 1-2 parts of an antibacterial agent, 4-8 parts of a plasticizer, 3-5 parts of a compatilizer and 1-3 parts of a flame retardant. The novel flame-retardant cable material has excellent performance, good physical performance, wide temperature adaptation range, high-temperature resistance, good flame-retardant performance, antibacterial and anti-corrosion capacity and long service life.

The invention discloses an adhesive for a corrugated board and a preparation method of the adhesive and belongs to the technical field of adhesives. According to key points of the technical scheme, the adhesive for the corrugated board comprises the following components in parts by weight: 380-420 parts of corn starch, 47-49 parts of sodium hydroxide, 7-9 parts of an enhancer, 4-5 parts of a stabilizer, 4.5-5.5 parts of borax, 3-4 parts of a drier and 1-2 parts of a mildew preventive. The drier in the invention can achieve effects of obviously promoting evaporation of water and shortening curing time; and by matching the enhancer and the stabilizer, the crosslinking degree among starch molecules can be improved, tenacity and adhesive strength of the adhesive are improved, an adhesion cracking problem caused by excessive drying is avoided, so that the drying process is simple, and operations are facilitated.

The invention discloses high-temprature-resisting, mildew-proof and antibacterial type nano waterborne baking finish and a preparation method thereof. The baking finish is prepared from the followingcomponents in parts by weight: 10 to 40 parts of de-ionized water, 0.5 to 3.0 part of surface active wetting agent, 5 to 20 parts of nano titanium dioxide, 0 to 35 parts of auxiliary agent, 30 to 60 parts of waterborne acrylic resin, 4 to 12 parts of partially methylated amino resin, 2 to 6 parts of highly methylated amino resin, 1 to 5 parts of epoxy modified silane coupling agent, 5 to 10 partsof propylene glycol methyl ether and 1 to 3 parts of dimethylamino ethanol. The baking finish disclosed by the invention does not contain heavy metal, is safe and environmentally friendly and has no toxic and side effects, and meets REAH and ROHS; the baking finish can be used for food-grade package and passes through American FDA (Food and Drug Administration) authentication; the baking finish has a long-acting mildew-proof effect and the mildew-proof effect keeps 98 percent or more after five years; the baking finish has a strong adhesive force, can be used for hardware and also can be usedfor glass and ceramic base materials; the baking finish resists high temperature and is not decomposed and colored after being baked at 180 DEG C for 60min or more.
