Problems solved by technology

Existing spray glue products have high viscosity, and when they are directly filled into aerosol spray glue, poor atomization and clogged valves are prone to occur; as the base material of aerosol spray glue semi-finished products, the composition is also different from that of general spray glue , first of all to ensure that its viscosity is not too high, and at the same time the adhesion is not too bad; secondly, it can be stably miscible with the propellant

Abstract

The invention discloses an aerosol spray adhesive, which contains two components of a base material and a propellant. In the aerosol spray adhesive, the base material and the propellant are filled together in an aerosol seal pot with a valve. The formula of the base material comprises (by weight): thermo-plastic elastomer 8 to 12 parts, terpene resin 8 to 12 parts, C9 petroleum resin 5 to 8 parts, rosin glyceride 2 to 4 parts, ethyl acetate 8 to 12 parts, butyl acetate 12 to 18 parts, extraction solvent oil No.6 30 to 50 parts, BHT 0.2 to 1.0 parts, and naphthenic oil 1 to 2 parts. The aerosol spray adhesive has the advantages that the product is filled as aerosol and sealed in a pot, so that the product can be sprayed without the need of matched facilities when in use and is convenient in construction; the sprayed adhesive particles are fine and uniform to prevent wrinkling when being used for adhering fine and thin materials; and the product can be used for adhering various materials such as paper sheets, plastics, thick paper boards, foam and metal.

Description

technical field [0001] The invention relates to an aerosol type adhesive, in particular to an aerosol spray glue. technical background [0002] As a kind of adhesive, spray glue is widely used in industry and production. It has suitable viscosity, adhesive force and proper drying time. It can be sprayed on the surface of the adhered object with a spray gun to form a uniform adhesive layer. After spraying, it will be properly dried to press the adhered surface. The bonding process is completed. Compared with gluing processes such as roller coating and brush coating, the glue consumption is small and the sizing is uniform. [0003] At present, there are two main types of glue spray products on the market. One is SBS glue spray, which uses thermoplastic elastomer SBS as the main raw material, with low cost and good initial viscosity; the other is neoprene glue spray, which uses neoprene Rubber is the main raw material, with high bonding strength and good temperature resistan...
