Problems solved by technology

However, aromatic polynitroso compounds are flammable, explosive, highly toxic, and the three wastes in the production process are serious, so they are controlled products; lead salts are highly toxic and bioaccumulative, and are easy to generate dust, which is harmful to human health during production and use. And the ecological environment is very harmful, so many countries and regions have banned the use of

[0058]

[0059] Follow the steps below to synthesize the adhesion promoter:

[0060] a. Soak the porous inorganic filler in 30% silane coupling agent / acetone solution at 60°C for 4 hours, then filter and dry;

[0061] b. The modified filler obtained in the previous step and the polyolefin are internally mixed with an internal mixer at a temperature of 80°C for one hour.

[0062] c. After the colloid obtained from banburying is discharged, it is prepared into an aqueous dispersion according to a well-known method in the industry to obtain an adhesion promoter.

[0063] The formula number corresponding to the finished adhesion promoter is as follows:

Abstract

The invention relates to an adhesion promoter for bonding elastomers and metals and an adhesive composition. The adhesion promoter is prepared by using a porous inorganic filler as a bracket, performing surface treatment on a silane coupling agent, and then performing polyolefin-supported. The adhesive composition composed of the adhesion promoter contains at least one halogenated polyolefin, the adhesion promoter, at least one vulcanizing agent and at least one inert inorganic filler. According to the invention, due to the presence of the adhesion promoter, the adhesive composition can effectively bond various elastomers and hard base materials, and form a moderately hard transition layer between the elastomers and the hard base materials, so that the adhesion of the adhesive composition for the elastomers is promoted, and the adhesive force of the adhesive composition for the hard base materials is increased.

Description

technical field [0001] The invention relates to an adhesion promoter for bonding an elastomer and a metal substrate and an adhesive composition thereof. The adhesion promoter is prepared by using porous inorganic filler as a support, and then supporting polyolefin after surface treatment with a silane coupling agent. The adhesive composition consisting thereof contains at least one halogenated polyolefin, an adhesion promoter, at least one vulcanizing agent and at least one inert inorganic filler. Due to the existence of the adhesion promoter, the adhesive composition can effectively bond various elastomers and hard substrates, and form a transition layer with moderate hardness between the elastomer and the hard substrate to promote the adhesion of the adhesive. The bonding of the composition to the elastomer increases the adhesion of the adhesive composition to the hard substrate. Background technique [0002] The elastic body and the metal are bonded by adhesive, which i...
