Embodiment 1

[0016] The preparation method of epoxy resin for dipping polyester cord fabric of automobile tires in this embodiment comprises the following steps:

[0017] In the first step, the temperature of polypropylene glycol diglycidyl ether and diethylene glycol diglycidyl ether is respectively raised to 70°C for distillation under reduced pressure, and part of the water and toluene are removed until the water solubility reaches 99%;

[0018] In the second step, by weight, 18 parts of propylene glycol diglycidyl ether and 75 parts of diethylene glycol diglycidyl ether are heated to 60°C, and 2 parts of sodium dodecylbenzenesulfonate and 0.1 parts of The simethicone oil is kept warm for 1 hour to obtain epoxy resin for dipping polyester cord fabric of automobile tires.

Embodiment 2

[0020] The preparation method of epoxy resin for dipping polyester cord fabric of automobile tires in this embodiment comprises the following steps:

[0021] In the first step, glycerol triglycidyl ether and ethylene glycol diglycidyl ether are respectively heated to 80°C for vacuum distillation to remove part of water and toluene until the water solubility reaches 99%;

[0022] In the second step, by weight, 20 parts of glycerol triglycidyl ether A and 77.3 parts of ethylene glycol diglycidyl ether are warmed up to 60°C, and 2.6 parts of sodium dodecylbenzenesulfonate and 0.1 part of simethicone oil was incubated for 2 hours to obtain an epoxy resin for automobile tire polyester cord impregnation.

Embodiment 3

[0024] The preparation method of epoxy resin for dipping polyester cord fabric of automobile tires in this embodiment comprises the following steps:

[0025] In the first step, dipropylene glycol diglycidyl ether and butyl glycidyl ether were respectively heated to 90°C for distillation under reduced pressure to remove part of the water and toluene until the water solubility reached 99%;

[0026] In the second step, by weight, 22 parts of dipropylene glycol diglycidyl ether and 78 parts of butyl glycidyl ether are heated to 60°C, and 3 parts of sodium dodecylbenzenesulfonate and 02 parts of di Methyl silicone oil, heat preservation 3 hours, obtains the epoxy resin for automobile tire polyester cord fabric impregnation.

[0027] The performance parameter of embodiment 1-3 is as follows:

[0028]

[0029]

[0030] Thus, it is concluded that the epoxy resin for automobile tire polyester cord dipping prepared by the method of the present invention has a higher epoxy value, ...

Abstract

The invention relates to a preparation method of an epoxy resin used for automobile tyre terylene tyre fabric impregnation. The preparation method comprises following steps: an alcohol glycidyl etherA and an alcohol glycidyl ether B are subjected to heating underpressure distillation respectively to remove a part of water and toluene; 18 to 22 parts of the treated alcohol glycidyl ether A, and 75to 80 parts of the treated alcohol glycidyl ether B are heated to 60 DEG C, 2 to 3 parts of an emulsifier and 0.1 to 0.5 part of an antifoaming agent are added, thermal insulation treatment is carried out for 1 to 3h so as to obtain the epoxy resin used for automobile tyre terylene tyre fabric impregnation. The preparation method is simple; cost is low; the epoxy resin possesses higher epoxy value and strength, is capable of satisfying market requirements, and is promising in application prospect.

Description

technical field [0001] The invention relates to the field of polymer material preparation, in particular to a preparation method of an epoxy resin used for dipping polyester cord fabrics of automobile tires. Background technique [0002] Epoxy resin is an important material used for impregnation of polyester cord fabric for car tires or mine conveyor belt skeleton materials. my country has long relied on EX-313 epoxy resin imported from Japan to meet domestic demand, but due to the high price of imported products High lead to polyester cord fabric production cost is too high and lose market competitiveness. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing epoxy resin for dipping polyester cord fabrics of automobile tires, to solve the problem in the prior art that the cost of polyester cord fabrics is high due to the high price of epoxy resins. [0004] The invention provides a kind of preparation method of the ep...
