Problems solved by technology

Among them, water-based polyurethane spray glue needs to be heated and activated before it can be used. However, the glue spray industry generally adopts cold bonding, so the use of water-based polyurethane spray glue is limited.
[0003] The Chinese invention patent application with the publication number CN106753050A discloses a water-based environmental protection spray glue. The water-based environmental protection spray glue uses water-based neoprene latex and water-based acrylic emulsion as the main raw materials, and is prepared by dissolving in deionized water under the action of additives. As a result, although the water-based environmentally friendly spray glue has excellent cohesiveness, environmental protection and non-toxicity, its initial adhesion, quick-drying performance, and thermal insulation and fire resistance are limited, and it is not suitable for applications that require quick-drying or high initial adhesion. In addition, although it can realize the bonding between the same material such as sponge, it cannot realize the bonding between sponge and wood, sponge and non-woven fabric, wood and non-woven fabric, thus limiting the spraying method. The scope of use of glue in the furniture and decoration industry; in addition, when the above-mentioned water-based environmentally friendly spray glue is used in large-scale spraying, a large amount of water mist will be generated, making it easy for the staff to breathe the above-mentioned water-based environmentally friendly spray glue into the respiratory tract, affecting health

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a thermal insulation water-based adhesive and its preparation method and application. Background technique [0002] Spray glue is a kind of adhesive with suitable viscosity, which can tightly bond the interface of two different substances and play the role of transfer application. It is widely used in leather, fixture and decoration industries. At present, the spray glue on the market is mainly solvent-based spray glue (oily spray glue). All spray glues on the market contain toxic or highly toxic solvents (alkane solvent oil, acetone, methyl ethyl ketone, chlorinated hydrocarbons, benzene, toluene, xylene), which will cause artificial poisoning to varying degrees during the use of the product, and Seriously pollute the environment, such as toluene and chlorinated solvents, these organic solvents enter the air, seriously affect people's living environment, and damag...
