Embodiment 1

[0009] After crushing 100g of sisal, soak it in 1L of 0.5mol / L hydrogen peroxide for 20 hours, then add 10g of amylase for enzymolysis, filter after the enzymolysis is complete, soak the filter residue in 1mol / L formaldehyde solution for 10 hours, after soaking Add 0.5g of fiber modifier, and dry to obtain modified sisal fiber.

Embodiment 2

[0011] After crushing 100g of sisal, first soak it in 1L of 1mol / L hydrogen peroxide for 15 hours, then add 10g of amylase for enzymolysis, filter after the enzymolysis is complete, soak the filter residue in 1.5mol / L formaldehyde solution for 8 hours, after soaking Add 0.5g of fiber modifier, and dry to obtain modified sisal fiber.

Abstract

The invention provides a manufacturing process for a modified sisal fiber used for plastics. According to the invention, sisal hemp is minced and then immersed in a sodium hypochlorite solution; then amylase is added for enzymatic hydrolysis; filtration is carried out after enzymatic hydrolysis; an obtained filter residue is immersed in a diluted formaldehyde solution; a fiber modifier is added after immersion; and drying is carried out so as to obtain the modified sisal fiber. Addition of the modified sisal fiber into plastics enables toughness, antistatic performance and corrosion resistance of the plastics to be improved and an application scope of the plastics to be broadened.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a manufacturing process of modified sisal fibers for plastics. Background technique [0002] Sisal fiber is tough and wear-resistant, rigid and soft, elastic, will not harden at low temperature, corrosion-resistant and anti-static. Oilfield and other industries. And because the surface of sisal fiber has certain hydroxyl groups, it is easy to react with high molecular polymers, so it will have side reactions in the application process of plastic products, which will reduce the quality of products. Contents of the invention [0003] The purpose of the present invention is to provide a kind of manufacturing process of the modified sisal fiber for plastics aiming at the deficiencies of the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is as follows: a kind of manufacturing process of modified sisal fiber for plastics, the ...
