Embodiment 1

[0009] A styrene-butadiene rubber emulsion modifier comprises the following components by weight: 35 g of hydroxyethyl methacrylate, 15 g of alkyl resorcinol formaldehyde resin, and 3 g of hexamethoxymethyl melamine.

[0010] The preparation method is to weigh the raw materials according to the above ratio, add 3 times the amount of deionized water after mixing, conduct microwave heating at a frequency of 5000MHz for 10 minutes, and then rapidly cool down to 15°C with liquid nitrogen.

Embodiment 2

[0012] A styrene-butadiene rubber emulsion modifier comprises the following components by weight: 50 g of hydroxyethyl methacrylate, 30 g of alkyl resorcinol formaldehyde resin, and 5 g of hexamethoxymethylmelamine.

[0013] The preparation method is to weigh the raw materials according to the above ratio, add 3 times the amount of deionized water after mixing, microwave heating at a frequency of 20000MHz for 20 minutes, and then rapidly cool down to 25°C with liquid nitrogen.

Embodiment 3

[0015] A styrene-butadiene rubber emulsion modifier comprises the following components by weight: 43 g of hydroxyethyl methacrylate, 19 g of alkyl resorcinol formaldehyde resin, and 4 g of hexamethoxymethyl melamine.

[0016] The preparation method is to weigh the raw materials according to the above ratio, add 3 times the amount of deionized water after mixing, conduct microwave heating at a frequency of 15000MHz for 15 minutes, and then rapidly cool down to 20°C with liquid nitrogen.

Abstract

The invention discloses a styrene butadiene rubber emulsion modifying agent which comprises the following components in parts by weight: 35-50 parts of hydroxyethyl methacrylate, 15-30 parts of alkyl resorcinol formaldehyde resin and 3-5 parts of hexamethoxy methyl melamine. The styrene butadiene rubber emulsion modifying agent disclosed by the invention is simple in preparation method and less in environment pollution, and can reduce the ageing speed of styrene butadiene rubber and greatly prolong the service life of the styrene butadiene rubber under the precondition that the rubber quality is ensured.

Description

technical field [0001] The invention relates to a styrene-butadiene rubber emulsion modifier. Background technique [0002] In the past production of styrene-butadiene rubber, the product was single and of poor quality, which could not meet the needs of diversification. Styrene-butadiene rubber modifiers refer to various materials that can modify styrene-butadiene rubber. Facing the increasingly wide market demand, there are more and more types of modifiers for styrene-butadiene rubber, but most of them have the effect Unable to last and accelerate the aging of rubber defects. Contents of the invention [0003] The object of the present invention is to provide a styrene-butadiene rubber emulsion modifier capable of delaying the aging speed of styrene-butadiene rubber and changing the use effect of styrene-butadiene rubber for the above-mentioned defects in the prior art. [0004] In order to achieve the above object, the technical solution provided by the present inventi...
