preparation example Construction

[0025] The preparation process of the environment-friendly fiber skeleton material dipping liquid is as follows: stirring and aging the raw material components at 20-35° C. for 6-12 hours.

[0026] The dipping process of the environmentally friendly fiber skeleton material dipping solution: the fiber skeleton material is coated with the dipping solution by a two-bath dipping method; the fiber skeleton material is first immersed in the first bath dipping solution, and the dipping After drying and heat treatment, dry at 100-200 ° C, heat treatment at 180-240 ° C for 0.1-10 minutes; after the first bath of dipping liquid treatment, then dip in the environment-friendly fiber skeleton material dipping liquid , drying at 100-200°C, and heat treatment at 180-240°C for 0.1-10min.

[0027] The formula of the first bath dipping solution is: the mass content of each component is 0.003%-0.005% of sodium hydroxide, 0.5%-2% of polyfunctional glycidyl ether, 2%-8% of caprolactam-blocked isoc...

Abstract

The invention discloses environment-friendly fiber framework material impregnation liquid, a preparation method thereof and an application of the liquid. The liquid comprises, by weight, 70-120 partsof rubber latex, 5-50 parts of blocked isocyanate, 0.5-5 parts of ammonium hydroxide and the rest water, and the total solids content of the impregnation liquid is 8%-30%. The prepared impregnation liquid does not contain hazardous substances such as resorcinol and formaldehyde and cannot pollute environments and effectively reduces occupational hazard. The impregnation liquid is simple and convenient in preparation process step, impregnation processes are easily operated, impregnated fiber and rubber has excellent bonding effect, and the impregnation effect of the liquid is better than that of traditional RFL (resorcinol and formaldehyde latex).

Description

technical field [0001] The invention relates to the technical field of dipping liquid, in particular to an environment-friendly dipping liquid for fiber skeleton material and a preparation process thereof. Background technique [0002] In the rubber industry, rubber products are widely used, especially in the application of rubber-fiber composite materials in the tire industry, which is an irreplaceable role. As an orthopedic material, rubber enables rubber composites to have strength and stiffness while maintaining elasticity. In this way, the tire has excellent characteristics such as tear resistance, high strength, and high modulus. Due to the chemical inertness of the fiber surface, the bonding strength of the fiber / rubber interface is low. In order to improve the bonding strength of the two, the fiber is usually pretreated by dipping. [0003] Traditionally, through continuous exploration and research, people generally use resorcinol-formaldehyde-latex type adhesive d...
