Problems solved by technology

However, this method of pretreatment and curing requires high baking temperature and long baking time, so it will consume a lot of energy; at the same time, due to the low curing reaction rate, it will emit a large amount of phenol, formaldehyde, ammonia nitrogen waste gas, which seriously pollutes the environment.

Abstract

The invention relates to a cord fabric dipping and curing technology based on electronic radiation processing. Sodium hydroxide, resorcinol and formaldehyde are condensed in water at the room temperature to be prepared into a solution (1); the solution (1) is added into butadiene vinyl-pyridine rubber latex, a JU-6 fiber activity adhesive is added after curing, and a solution (2) is prepared; the solution (2) and TMPTA / PETA resin of a trifunctional group or EGDMA / JPGDA resin of a bifunctional group are mixed and uniformly dispersed in a vacuum reaction kettle at a high speed at the room temperature, and a radiation-sensitive dipping finishing agent is prepared; the radiation-sensitive dipping finishing agent is added into a dipping machine, processed on a terylene / chinlon chemical fiber fabric by a single-dip single-roll process and cured by an electronic beam radiation device with the energy level higher than 400 KeV, and a dipped cord fabric is obtained. Dipped resin which can be affiliative with chemical fibers and rubber can be selected and wholly and quickly participates in a cross-linking reaction under the radiation condition, the curing is rapid, the curing time is short, energy consumption is low, the pretreatment efficiency is high, the flow path is short, and the cost is low.

Description

technical field [0001] The invention relates to a cord fabric dipping and curing process based on radiation processing. Background technique [0002] Cord fabric is a skeleton fabric used for rubber products woven with strong strands as warp and medium and fine single yarns as weft. The fiber material is mainly chemical fiber polyester and nylon. As the skeleton material of rubber products, cord fabric is widely used in conveyor belts, automobile tires and other fields. However, due to the low polarity of chemical fiber molecules, high crystallinity, and inactive chemical properties, the adhesion to rubber is poor. In order to improve the adhesion between chemical fiber fabrics and rubber, chemical fiber fabrics need to be pretreated. The widely used chemical fiber fabric pretreatment method is to heat on the chemical fiber fabric to cure some impregnated resins with hydroxyl, amide, isocyanate, etc. that can be compatible with chemical fibers and rubber, so as to achieve ...
