Water-soluble spraying glue and method for preparing same

Abstract

The invention discloses waterborne spray gel which is characterized in that the waterborne spray gel contains(based on weight portion) 100-150portions of waterborne neoprene latex, 20-60 portions of acrylic latex, 60-100 portions of waterborne tackifying resin, and 5-20 portions of waterborne dope drier. The preparation method includes the following steps: firstly, putting the materials of 100-150portions of waterborne neoprene latex, 20-60 portions of acrylic latex and 60-100 portions of waterborne tackifying resin into a reactor, mixing and blending to be even; putting the waterborne dope drier into the reactor, blending to be even, then cooling and discharging. The adhesive prepared can be used for spraying and splicing furniture such as sofas, folding screens and swivel chairs, for splicing inside automobiles and for splicing foams; the waterborne spray gel has the advantages of excellent adhesive property, good heat resisting property and low VOC content and is flame-retardant, anti-corrosion, waterborne and environment-friendly; the waterborne spray gel can effectively protect the work environment and greatly reduce the accidents of poisoning caused by solvent spray gel products and industrial diseases; therefore, the waterborne spray gel is an ideal substitute for part of current solvent spray gel.

Description

Technical field [0001] The invention relates to an adhesive, in particular to spray glue and a preparation method thereof. Background technique [0002] Spray glue is a commonly used adhesive in the market. It is widely used in the furniture industry, decoration material industry, and luggage production industry, especially sofas, swivel chairs, screens, fabrics, pillows, kitchen cabinet board bonding, foam insulation boards, Handbags, luggage, etc., are the most widely used. At present, the spray glue on the market has always used solvent rubber adhesives. This kind of well-known technical adhesives generally use solvents. By stirring, SBS thermoplastic styrene butadiene rubber or neoprene rubber is added to a certain amount of tackifying resin. The proportion is put into the reaction kettle and stirred until it is dissolved. The solid content of this type of adhesive is generally between 20-30%, so in the process of use, 70-80% of the organic solvent (mainly toluene, chlorinate...

AI Technical Summary

Problems solved by technology

Developed countries such as Germany, the United States, and Japan have launched water-based polyurethane and water-based neoprene products, but due to different shortcomings, the promotion of products has been greatly affected

The use of water-based polyurethane adhesives generally needs to be activated by heating before use, but the industries that use glue spray are generally cold-bonded and do not need heating, so water-based polyurethane is not suitable for the use of glue spray industries; pure water-based neoprene has a certain pressure Sensitivity, but due to high cost, slow drying speed, high cost, etc., it is also not suitable for the use of the above industries
