Problems solved by technology

Even so, there are still potential environmental and safety risks
[0004] The resorcinol in RFL also has certain toxicity. Although it is not easy to volatilize, it is difficult to deal with the waste RFL treatment liquid. When the skeleton material impregnated with RFL is recycled and processed, it is easy to produce toxic and harmful gases such as benzene when heated or incinerated. , increasing the difficulty of solid waste disposal

Abstract

The invention discloses a glue dipping solution for an environment-friendly fiber skeleton material, a preparation method and a dipping method. The dipping solution includes deionized water, butylpyridine latex, polybutadiene latex, maleic anhydride-trimethylolpropane copolymer, sorbitol polyoxyethylene ether, acrylate-trimethylolaminomethane copolymer, poly Carbodiimide, blocked isocyanate. The preparation method comprises: adding deionized water into a reaction kettle, adding the above-mentioned components while stirring at normal temperature, adding each component after stirring and mixing evenly, and then adding the next component to obtain the product. The dipping solution of the present invention does not contain toxic and harmful substances such as resorcinol and formaldehyde; the preparation process is simple, the operation is convenient, and it is prepared and used immediately without aging; after the dipping treatment is completed, no volatile toxic and harmful substances are produced; the present invention The impregnated fiber skeleton material and rubber have a good bonding effect.

Description

technical field [0001] The invention relates to the technical field of dipping, in particular to a dipping solution for an environment-friendly fiber skeleton material, a preparation method and a dipping method. Background technique [0002] The fiber skeleton material used in natural rubber usually uses a conventional RFL impregnation system to improve the fiber-rubber bonding. RFL is the abbreviation of the traditional resorcinol-formaldehyde-latex system, which was invented by DuPont and is still in use today. Because RFL is similar to the "meta-white" adhesive system in rubber, the fiber skeleton material impregnated with RFL usually has better adhesion to the rubber of the "meta-white" system. [0003] However, formaldehyde in RFL is very volatile and highly carcinogenic, and will cause harm to the environment and human body during the preparation and use of the dipping treatment solution. In order to avoid this problem, volatile organic compounds are usually recovere...
