Embodiment 1

[0034] The temperature of the kneader is raised to 90°C, 40 parts of butyl 268 rubber, 20 parts of brominated butyl rubber, 20 parts of polyisobutylene B50, 100 parts of polyisobutylene B12, 30 parts of SBS, 100 parts of octyl phenolic resin, 10 parts of zinc oxide 10 parts, antioxidant 1010 2 parts were added to the kneader, after fully kneading for 1 hour, 10 parts of mineral oil, 80 parts of decabromodiphenyl ether, 40 parts of antimony trioxide, 150 parts of aluminum hydroxide, and 30 parts of carbon black were sequentially added After the addition is completed, keep the temperature at 130°C for 2 hours and then discharge the material. After cooling to room temperature, a flame-retardant hot-melt pressure-sensitive adhesive is obtained.

Embodiment 2

[0036] The temperature of the kneader is raised to 90°C, 20 parts of butyl 268 rubber, 60 parts of brominated butyl rubber, 30 parts of polyisobutylene B50, 120 parts of polyisobutylene B12, 40 parts of SBS, 70 parts of octyl phenolic resin, 15 parts of zinc oxide 3 parts, antioxidant 1010 3 parts were added to the kneader, after fully kneading for 2 hours, 20 parts of mineral oil, 110 parts of decabromodiphenyl ether, 50 parts of antimony trioxide, 100 parts of aluminum hydroxide, and 30 parts of carbon black were sequentially added After the addition is completed, keep the temperature at 140°C for 3 hours and then discharge the material. After cooling to room temperature, a flame-retardant hot-melt pressure-sensitive adhesive is obtained.

Embodiment 3

[0038] The temperature of the kneader is raised to 110°C, 50 parts of butyl 268 rubber, 40 parts of brominated butyl rubber, 50 parts of polyisobutylene B50, 150 parts of polyisobutylene B12, 50 parts of SBS, 80 parts of octyl phenolic resin, 20 parts of zinc oxide 4 parts, antioxidant 1010 were added to the kneader, kneaded fully for 2 hours, then added 15 parts of mineral oil, 150 parts of decabromodiphenyl ether, 60 parts of antimony trioxide, 120 parts of aluminum hydroxide, 30 parts of carbon black After the addition is completed, keep the temperature at 140°C for 3 hours and then discharge the material. After cooling to room temperature, a flame-retardant hot-melt pressure-sensitive adhesive is obtained.

Abstract

The invention relates to a flame retardant-type waterproof sealing hot-melt pressure-sensitive adhesive. The flame retardant-type waterproof sealing hot-melt pressure-sensitive adhesive comprises butyl rubber 268, brominated butyl rubber, polyisobutene B50, polyisobutene B12, octyl phenolic resin, thermoplastic elastomer SBS (Styrene Butadiene Styrene), mineral oil, deca-brominated diphenyl ether, antimonous oxide, aluminium hydroxide, zinc oxide, an antioxidant 1010 and carbon black. The hot-melt pressure-sensitive adhesive with high flame retardant property is obtained by selecting the resin with very good waterproof sealing property and the rubber system in combination with a flame retardant with the excellent synergistic flame retardant property according to a formula system while the waterproof sealing property and the bonding strength of the hot-melt pressure-sensitive adhesive are ensured. The prepared pressure-sensitive adhesive has very high bonding strength at the temperature of 40-80 DEG C, excellent insulation property, waterproof property, flame retardant property and sealing property and can be used for producing waterproof sealing tapes, wrapping wire and cable insulations, sealing pipelines and the like.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to the field of pressure-sensitive adhesives. Background technique [0002] With the continuous development of science and technology, the power of electronic and electrical equipment continues to increase, and the places where these equipment are applied are also more extensive and demanding. The application of high-power electrical appliances makes the requirements for wires and cables higher and higher, especially in the joints of wires and cables. If the sealing of the joints is not good and the water resistance is poor, there will be a very large risk, which may cause the equipment to be short-circuited and damaged or cause a fire. Therefore, the products applied to the joints must have good waterproof and sealing properties, and the higher the flame retardant level, the better. Contents of the invention [0003] The present invention starts with the formulation system, selects the...
