Manufacture method for natural fiber net cover

Abstract

The invention relates to a manufacture method for a natural fiber net cover. The manufacture method comprises the following steps: 1, a natural fiber raw materials is subjected to alkali treatment or coupling reagent treatment for modification; 2, the modified natural fiber raw material is continuously stacked to be laminated material through resin liquid coating, or the modified natural fiber raw material is cut into short cut natural fiber; the short cut natural fiber is jointly mixed and dispersively dipped in the resin liquid to form resin paste, and the resin paste is made into a laminated material through roll pressing; 3, the laminated material is cut to obtain a circular natural fiber net cover blank and leftover materials; and 4, the natural fiber net cover blank is subjected to low-temperature curing to form the natural fiber net cover. The natural fiber adopted by the manufacture method is a biological renewable resource, so that a sustainable development idea is met. Compared with a fiber net cover manufactured from glass fiber in the prior art, at the same state, the fiber net cover manufactured from the natural fiber has the advantages that the fiber net cover can naturally degrade, so that no harm is caused to a human body and the environment; the mechanical strength is equivalent; and the production energy consumption is lower.

Description

[0001] The invention relates to a fiber net cover for making emery cloth wheels, polishing wheels, etc., in particular to a preparation method of a natural fiber net cover. Background technique [0002] In the prior art, the raw materials used to make fiber mesh covers such as emery cloth wheels and polishing wheels are glass fibers, and the glass fiber powder produced in the production process or in the middle of the use process of the glass fiber mesh covers has certain damage to the human body and the glass fiber is in the It cannot be degraded in the natural environment, so the fiber mesh cover made of glass fiber can only be disposed of by deep burial, landfill, incineration, etc. The waste generated after use is very difficult and pollutes the environment. [0003] Therefore, further improvements are required. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing a natural fiber mesh cover with high mechanical stre...

[0002] In the prior art, the raw materials used to make fiber mesh covers such as emery cloth wheels and polishing wheels are glass fibers, and the glass fiber powder produced in the production process or in the middle of the use process of the glass fiber mesh covers has certain damage to the human body and the glass fiber is in the It cannot be degraded in the natural environment, so the fiber mesh cover made of glass fiber is used. The waste generated after use can only be disposed of by deep burial, landfill, incineration, etc., which is difficult to handle and causes great environmental pollution.
