Problems solved by technology

The solid content of the prepared adhesive is between 20-30%, so harmful solvents such as toluene and chlorinated solvents that use 70-80% of the glue will be discharged into the atmosphere during use; there is another important thing about spray glue on the market The disadvantage is that the operation and use of building decoration often cause rework and glue repair, which affects construction efficiency

Embodiment 1

[0021] Composite material: According to formula 1 in Table 1, polyether polyol or polyester polyol, cell opener, defoamer, foam stabilizer, and catalyst are added to the reaction kettle according to the formula ratio and mixed evenly to prepare white material. Pour the combined white material into the aerosol can; add diphenylmethane diisocyanate according to the formula ratio, press the valve, fill in dimethyl ether and propylene butane in turn, shake well; test the product performance.

Embodiment 2～5

[0023] Listed formula by table 1, technological process is with example 1. In Examples 2-5, the universal foam glue with the same performance can also be prepared by changing different additives.

Abstract

The invention relates to an environment-friendly all-purpose automatic-spray polyurethane adhesive. The polyurethane adhesive is prepared from, by weight, 30-100 parts of polyether glycol and / or polyester polyol, 1-15 parts of hole opening agent, 0-2 parts of defoaming agent, 0-3 parts of foam stabilizer, 0.2-5 parts of catalyst, 30-70 parts of foaming agent and 30-150 parts of polyisocyanate. The novel environment-friendly all-purpose automatic-spray adhesive combining a high-technology polyurethane aerosol technology has ultrahigh permanent viscous force and is wide in application range, rapid in curing and convenient and rapid to use; more importantly, the polyurethane adhesive belongs to a waterborne cured product, is free of poisonous and harmful solvents such as benzene, formaldehyde and volatile halogenated hydrocarbons and belongs to a green and environment-friendly novel adhesive product.

Description

technical field [0001] The invention relates to a polyurethane adhesive, in particular to a polyurethane environmental protection universal self-spraying adhesive and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's construction industry, spray glue, as a commonly used adhesive in the market, is widely used in furniture, decoration materials and luggage production industries, especially the most widely used for bonding sofas, swivel chairs, and cabinet boards. At present, the spray glue on the market has been mainly using solvent rubber adhesives. This kind of adhesives of known technology uses solvents to mix SBS thermoplastic styrene-butadiene rubber or neoprene rubber and add tackifying resins. A certain proportion is put into the reaction kettle and stirred and dissolved. The solid content of the prepared adhesive is between 20-30%, so harmful solvents such as toluene and chlorinated solvents that us...
