Embodiment 1

[0033] A high-density wear-resistant type adhesive for environment-friendly tires, comprising:

[0034] 250 parts of hexamethylolmelamine;

[0035]40 parts of di-tert-butylbenzothiazole;

[0036] 10 parts of internal lubricants, which are any one or more of stearic acid, calcium stearate or fatty acid lower alcohol esters. The internal lubricant can reduce the cohesion between polymer molecules inside the polymer, further control the degree of polymerization of reactants, and prevent the gel phenomenon caused by self-polymerization.

[0037] 60 parts of film-forming compound, the film-forming compound is composed of hydroxypropyl methylcellulose, arabinose, polyvinyl alcohol and starch according to the mass ratio of 3:1:2:2. All film-forming compounds are hydroxyl-containing polymers. By adding film-forming compounds to form film layers on the inside and outside of the original adhesive, the bonding strength and aging resistance of the adhesive can be further improved.

Embodiment 2

[0056] This embodiment is basically the same as Embodiment 1, the difference is:

[0057] A high-density wear-resistant type adhesive for environment-friendly tires, comprising:

[0058] 200 parts of hexamethylolmelamine;

[0059] 50 parts of di-tert-butylbenzothiazole;

[0060] 8 parts of internal lubricant, the internal lubricant is stearic acid, the internal lubricant can play a role in reducing the cohesion between polymer molecules inside the polymer, further control the degree of polymerization of the reactant, and prevent the gel produced by self-polymerization Phenomenon.

[0061] 50 parts of film-forming compound, the film-forming compound is composed of hydroxypropyl methylcellulose, arabinose, polyvinyl alcohol and starch according to the mass ratio of 3:1:2:2. All film-forming compounds are hydroxyl-containing polymers.

Embodiment 3

[0076] This embodiment is basically the same as Embodiment 1, the difference is:

[0077] A high-density wear-resistant type adhesive for environment-friendly tires, comprising:

[0078] 220 parts of hexamethylolmelamine;

[0079] 45 parts of di-tert-butylbenzothiazole;

[0080] 9 parts of internal lubricant, described internal lubricant is calcium stearate, and internal lubricant can play the effect of reducing the cohesive force between polymer molecules inside the polymer, further controls the polymerization degree of reactant, prevents the coagulation that self-polymerization produces glue phenomenon.

Abstract

The invention discloses an adhesive for high-density wear-resistant environment-friendly tires and a preparation method thereof. The adhesive comprises: 200-250 parts of hexamethylolmelamine, 40-50 parts of di-tert-butyl Benzothiazole, 8-10 parts of internal lubricant, 50-60 parts of film-forming compound, 15-20 parts of multibranched polymer, 4-6 parts of film-forming aid, 4-6 parts of defoamer, 3- 5 parts oily dispersing wetting agent, 2‑4 parts polymerizable emulsifier. In the preparation process of the adhesive, the present invention adds a film-forming compound and a multi-branched polymer, by adding a film-forming compound to form a film layer inside and outside on the basis of the original adhesive, the adhesive can be further improved. Excellent bond strength and aging resistance. In short, the adhesive prepared by the present invention through reasonable proportioning and multiple optimized process parameters has high bond strength, aging resistance and tear resistance, thereby improving the wear resistance and safety of tires, and the production process is green and environmentally friendly , which is of great practical significance to the development of energy conservation and emission reduction work in my country's rubber additives industry.

Description

technical field [0001] The invention belongs to the technical field of adhesive preparation, and in particular relates to an adhesive for high-density wear-resistant environment-friendly tires and a preparation method thereof. Background technique [0002] Rubber products are widely used for their excellent heat resistance, cold resistance, high toughness and certain strength. However, different rubber products often cannot be bonded well due to the different chemical properties of the main components. At this time, it is necessary to Adhesives are added between different rubbers to promote the combination of the two, and the overall performance of the adhesive itself determines the service life of the rubber product composition. [0003] Adhesives belong to the rubber additives industry. At present, my country has become a major country in the global rubber additives industry and tire industry. The rubber consumption and tire output both rank first in the world. According t...
