Embodiment 1

[0106] Material A: 100 grams of water glass, 30 grams of acrylic resin, 10 grams of redispersible rubber powder, 40 grams of quartz powder, 2 grams of zinc oxide

[0107] Material B: 91 grams of black material, 91 grams of styrofoam

[0108] Add water glass into the container, add quartz powder, zinc oxide and redispersible rubber powder in sequence, stir for a while, and finally add acrylic resin while stirring until uniform, which is material A, and pack it for later use. Mix the black material and styrofoam in equal amounts according to the formula, and stir evenly to obtain material B. Material A and material B are stored separately. When in use, pour material A and material B according to the formula 1:1 and stir evenly before applying. It is best to use it up within a quarter of an hour. The following is the load capacity when the large screw is bonded horizontally to the vertical wooden board, and the bottled water is hung at the end of the screw, that is, the bottle c...

Embodiment 2

[0111] Material A: water glass 50g acrylic resin 10g epoxy resin 10g talcum powder 18g titanium dioxide 2g sodium tripolyphosphate 0.5g sodium pyrophosphate 0.5g sodium dodecylbenzenesulfonate 0.5g zinc oxide 0.5g petroleum 2 grams of barium sulfonate A little tributyl phosphate

[0112] Material B: 31.3 grams of black material, 62.7 grams of styrofoam

[0113] First put water glass into the container, then put in sodium tripolyphosphate, sodium pyrophosphate, sodium dodecylbenzenesulfonate, defoamer, zinc oxide, barium petroleum sulfonate, talcum powder, titanium dioxide, epoxy resin, Stir for a while, and finally add acrylic resin while stirring until uniform, which is material A. Mix the black material into the styrofoam, stir well until it is uniform, and it is B material. When in use, pour material A and material B into the mixing tank at a ratio of 1:1 according to the required amount, and stir at high speed for 30 seconds to 1 minute. are conventional methods. ...

Abstract

The invention relates to a bonding rubber material, especially provides a binder or a thermosetting molding rubber cement for bonding and reinforcement of door cores of a fireproof door an antitheft door and bonding and production of building and decoration materials, and aims to provide a composite rubber material, with low cost, good bonding strength and rapid surface dry, which can be cured at room temperature. The composite rubber material is characterized in that the composite rubber material is composed of a water-based A material and a polyurethane prepolymer-containing B material, the ratio (weight ratio) of the A material to the B material is 0.5-1:0.5-1, the A material comprises 30-70% of water and / or water glass and / or silica sol, 19.5-48% of organic modifiers, and 12-55% of additives, the B material comprises polyurethane prepolymers with a content of being more than 30%, 8-24% of -NCO group, and 0-30% of synergists, The synergists are one or combination of more than one selected from a polymerization inhibitor, a blocking agent, a water glass curing agent and a diluting agent. The composite rubber material is advantaged by good bonding strength, flame retardance, thermal insulation, low price and environmental protection.

Description

technical field [0001] The invention relates to an adhesive glue, especially an adhesive or a thermosetting glue that can be used for bonding and strengthening fireproof doors and anti-theft door cores, as well as bonding and processing construction and decoration materials. Background technique [0002] Most of the bonding glue between the core material and the door panel of the existing fire doors and anti-theft doors is polyurethane foam, and its bonding strength is required to be not less than 0.5mPa. It is mainly polyester polyol or polyether polyol reacted with polyisocyanate. The formed polyurethane prepolymer containing residual -NCO groups is usually added with an appropriate amount of catalyst, stabilizer and 10-50% organic solvent. Generally, the content of -NCO groups is about 2%-6%, and has toughness Good, high bonding strength, easy to use, but the price is high; prepolymers and solvents are flammable, and burning produces thick black smoke and releases toxic g...
