Abstract

The invention relates to the technical fields of chemical engineering materials and preparation technologies thereof, and especially relates to an aqueous flame retardant spray adhesive and a preparation technology thereof. The preparation technology needs a simple device and has a simple process. The aqueous flame retardant spray adhesive which treats water as a diluting agent has the characteristics of no organic matter discharge, no pollution to human bodies or the environment, difficult spray gun obstruction, and no production or use danger. An aqueous resin which is the aqueous flame retardant spray adhesive has a high solid content high to 60%, saves a traffic transportation cost and also saves the liquid adhesive application amount of unit area. The aqueous spray adhesive has the advantages of strong heat resistance, excellent flame retardation performance, avoiding of the appearance of a sprayed product fire, and reduction of the continued diffusion of the fire.

Description

Technical field: [0001] The invention relates to the technical field of chemical materials and their preparation, in particular to a water-based flame-retardant spray glue and a preparation process thereof. Background technique: [0002] Spraying glue is a kind of spraying on the surface of objects to achieve a certain surface effect or to bond objects; at present, spraying glue has the following defects: [0003] 1. Most of the low-viscosity spray adhesives currently used in sofas, mattresses, pillows and other household products are chemical formulas in which thermoplastic rubber is dissolved in organic solvents and tackified resins, containing organic solvents such as benzene or methylene chloride, organic solvents It is a flammable and explosive dangerous product. Its existence will bring safety hazards to the production of adhesives and the enterprises that use the products. In addition, the volatilization and inhalation of organic substances and contact with the human ...
