For example, patent publication No. CN201210336061.6, "a plastic-rubber polymer composite synthetic resin adhesive" comprises p-tert-butyl phenol formaldehyde resin, chloroprene rubber, magnesium oxide, carbon-five-carbon-nine copolymerized petroleum resin, BTH antioxidant, methyl acetate (refined), ethyl acetate, dichloropropane, toluene and No. 120 solvent oil. The invention is characterized in that on the basis of giving full play to the advantages of the phenolic synthetic resin, magnesium oxide is added, chloroprene rubber linear high polymer material and carbon five carbon nine copolymerized petroleum resin with strong adhesiveness and good heat resistance are introduced, and high molecular reactions such as grafting, chelating and the like are carried out on a molecular structure to form a copolymer with the phenolic resin, so that the plastic-rubber high polymer compound high-performance synthetic resin adhesive with various comprehensive performances is obtained. The product of the invention not only has high bonding strength, good water resistance, heat resistance and chemical stability, but also has the composite high performance of the flexibility, the flexibility and the like of the plastic-rubber high polymer elastomer. But still fails to inhibit the concentration of combustible gases and reduce the volatility and activity of the gases, and has a low flash point.
For example, patent publication No. CN201210478873.4, a flame-retardant acrylate adhesive, mainly solves the problem that the existing acrylate adhesive burns when meeting spark sputtering after being cured. The flame retardant is mainly characterized by comprising (1) a main agent component) 25-60 parts of acrylate monomer at least containing 1 vinyl, 1-25 parts of methacrylic acid, 0-25 parts of elastomer, 1-25 parts of flame retardant, 0.5-8 parts of initiator and 0.1-5 parts of stabilizer; (2) curing agent component) 25-60 parts of acrylate monomer at least containing 1 vinyl, 1-25 parts of methacrylic acid, 0-25 parts of elastomer, 1-25 parts of flame retardant and 1-10 parts of accelerator. The invention has the characteristics of improving the flash point of the acrylate adhesive, ensuring that the acrylate adhesive is not easy to burn and achieving the effect of non-combustion or self-extinguishing when the acrylate adhesive is away from fire, and is mainly used for the flame-retardant acrylate adhesive. However, the lower the flash point, the more dangerous it is, so that the flash point of the invention is not high and the safety factor is not ideal.
