Description
Technical Field
The invention relates to the technical field of adhesives, in particular to a preparation process of an ethylene-propylene-diene monomer conveyor belt high-adhesive-strength laminating adhesive.
Background
The rubber conveyer belt is used as a second large rubber industrial product and is mainly used for conveying materials in mines, wharfs, metallurgy, machinery and storage industries. The performance of the covering rubber can be divided into a flame-retardant conveying belt, a heat-resistant conveying belt, a wear-resistant conveying belt, an oil-resistant conveying belt, a cold-resistant conveying belt, an acid-alkali-resistant conveying belt, a common-purpose conveying belt and the like.
The ethylene propylene diene monomer rubber has the characteristics of high mechanical strength, low price, excellent ozone resistance, weather resistance, heat resistance and low temperature resistance and excellent electrical insulation property, has better resistance to animal and vegetable oil than natural rubber and styrene-butadiene rubber, has air permeability similar to that of the natural rubber, and is widely used as a main body material of a conveyor belt covering rubber, and a raw rubber system which is used by 2-3 of the natural rubber, the styrene-butadiene rubber and butadiene rubber is generally adopted for rubberizing of corresponding products. However, because the ethylene propylene diene monomer rubber has poor self-adhesion and mutual adhesion, the transition rubberizing is needed to be used between the covering rubberizing and the belt blank to realize the adhesion of the covering rubberizing and the belt blank, but the adhesive strength of the existing transition rubberizing is difficult to reach the standard requirement, so that the ethylene propylene diene monomer conveying belt is easy to generate delamination phenomenon, and the service life of the ethylene propylene diene monomer conveying belt is influenced.
Disclosure of Invention
The invention provides a preparation process of high-adhesive-strength laminating adhesive for an ethylene-propylene-diene monomer conveyor belt, which solves the problem of low adhesive strength of transition laminating adhesive used between a covering adhesive and a belt blank in the related art.
The technical scheme of the invention is as follows:
the high-adhesive-strength laminating adhesive for the ethylene propylene diene monomer conveyor belt comprises the following components in parts by mass: 100 parts of ethylene propylene diene monomer, 40-50 parts of filler, 8-15 parts of softener, 8-10 parts of activator, 1-3 parts of anti-aging agent, 3-5 parts of plasticizer, 3-5 parts of adhesive, 0.5-1 part of accelerator and 3-5 parts of vulcanizing agent.
A preparation process of an ethylene propylene diene monomer conveyor belt high-adhesive-strength laminating adhesive comprises the following steps: and plasticating the ethylene propylene diene monomer, adding the rest components, and mixing to obtain the high-adhesive-strength laminating adhesive for the ethylene propylene diene monomer conveyor belt.
The ethylene-propylene-diene monomer conveying belt sequentially comprises a covering adhesive, the ethylene-propylene-diene monomer conveying belt high-adhesive-strength laminating adhesive of claim 1, a plurality of layers of EP polyester cloth, the ethylene-propylene-diene monomer conveying belt high-adhesive-strength laminating adhesive of claim 1 and the covering adhesive from top to bottom; the EP polyester cloths are connected by rubberizing;
the covering adhesive comprises the following components in parts by mass: 100 parts of ethylene propylene diene monomer, 10-15 parts of glass powder, 40-50 parts of filler, 10-20 parts of plasticizer, 4-8 parts of softener, 9-12 parts of activator, 0.5-1 part of accelerator, 3-6 parts of adhesive, 1.5-2.5 parts of anti-aging agent and 4-6 parts of vulcanizing agent;
the rubberizing comprises the following components in parts by mass: 10 parts of natural rubber, 20 parts of styrene-butadiene rubber, 100 parts of reclaimed rubber, 30-40 parts of filler, 2.5-4.5 parts of adhesive, 3-5 parts of softener, 5-8 parts of activator, 1-2 parts of anti-aging agent, 1-2 parts of accelerator, 0.1-0.5 part of scorch retarder and 2-4 parts of vulcanizing agent.
As a further technical scheme, the reclaimed rubber is tire reclaimed rubber.
As a further technical scheme, the number of the EP polyester cloths is more than 2.
As a further technical scheme, the rubberizing also comprises 2-4 parts of compatibilizer; the compatibilizer comprises one or more of 3-aminopropyl triethoxysilane, N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane and 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane.
The surface of the reclaimed rubber is inert, so that the reclaimed rubber is a material containing a cross-linked structure and composed of rubber, carbon black, a softener, a vulcanization accelerator and the like, has poor compatibility with natural rubber and styrene-butadiene rubber, and the inventor improves the compatibility between the reclaimed rubber and the natural rubber and improves the mechanical property and the adhesive property of the rubberizing by adding 3-aminopropyl triethoxysilane, N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane and 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane as compatibilizers.

As can be seen from Table 2, the tensile strength of the rubberizing provided by the invention is more than 15.3MPa, the rubberizing has good mechanical properties, and meanwhile, the adhesive strength of the rubberizing and the EP polyester cloth is more than 21.2N/mm, so that the rubberizing has excellent adhesive property.
Examples 4 to 6 are each prepared by adding 3-aminopropyl triethoxysilane in example 4, N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane in example 5, and 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane in example 6, and the resulting pastes of examples 4 to 6 have higher tensile strength and adhesive strength to EP polyester cloth than in example 1. It is shown that 3-aminopropyl triethoxysilane, N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane and 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane can improve the mechanical properties and adhesive properties of the adhesive tape.
Example 8 the mass ratio of N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane to 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane in example 8 was 1:1, the mass ratio of N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane to 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane in example 7 was 3:1, the mass ratio of N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane to 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane in example 9 was 1:3, and the tensile strength of the resulting capstock to EP polyester cloth of example 8 was better than that of example 7 and example 9. Indicating that the resulting tape had the best chemical and adhesive properties when the mass ratio of N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane to 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane was 1:1.
Example 10 in comparison with example 8, the N- (hydroxyethyl) -N-methylaminopropyl trimethoxysilane added in example 8 had a lower tensile strength than 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane, the 3-aminopropyl triethoxysilane added in example 10 than 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxysilane, and the adhesive strength to EP polyester cloth obtained in example 10 was not as good as that of example 8. The effect of improving the mechanical property and the adhesive property of the rubberizing is better when the N- (hydroxyethyl) -N-methylaminopropyl trimethoxy silane is matched with 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxy silane, than when the 3-aminopropyl triethoxy silane is matched with 3- [ bis (2-hydroxyethyl) amino ] propane-triethoxy silane.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
