Description
Technical field
The present invention relates to the sizing agent technical field, particularly, relate to a kind of pair of component water-soluble environmental protection glue spraying and preparation method thereof.
Background technology
Glue spraying is a kind of suitable viscosity that has, and two kinds of different material interfaces are closely coupled together, and plays the tackiness agent of delivery applications effect, is widely used in furniture, leather and decoration industry.At present, on the market glue spraying is mainly take solvent-borne type glue spraying (oiliness glue spraying) as main.The solvent-borne type glue spraying contains a large amount of organic solvents, as toluene and chlorinated solvent, even contains the carcinogenic compositions such as benzene.These organic solvents enter air, have had a strong impact on people's living environment, and the infringement people are healthy.In addition, also there is inflammable and explosive problem in the solvent-borne type glue spraying, again and again initiation fire.Therefore, the environment-friendly type aqueous glue spraying that substitutes organic solvent with water solvent is competitively studied in countries in the world.In Germany, the developed countries such as the U.S. and Japan have released aqueous polyurethane glue spraying and watersoluble neoprene glue spraying.Wherein, the aqueous polyurethane glue spraying needs could use after heat-activated, and still, the glue spraying industry is generally all taked cold bonding, therefore, has limited the use of aqueous polyurethane glue spraying.The advantages such as and the watersoluble neoprene glue spraying is harmless to HUMAN HEALTH because of environmentally safe, and is nonpoisonous and tasteless, and become one of sizing agent industrial development direction.The watersoluble neoprene glue spraying as solvent, has organic solvent-free with water, does not contain heavy metal, and is tasteless, and the bonding tack is strong, fast drying, all advantages such as good of thermotolerance and anti-old property.
Yet, the applicant finds in use that at present on the market water-soluble spraying glue only can realize bonding between the sponge of identical material, but can not realize sponge and timber, sponge and non-woven fabrics, bonding between timber and non-woven fabrics, thereby, limited the use range of water-soluble spraying glue in furniture and decoration industry.
Summary of the invention
