Description

A kind of biodegradable environmental protection abrasive band and preparation method thereof

Technical field

The present invention relates to coated abrasive tool field, particularly to a kind of biodegradable environmental protection abrasive band and preparation method thereof.

Background technology

Since reform and opening-up, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " has become current domestic industry and sent out The main flow of exhibition, China's industry just progressively develops to the direction of intensive style, energy-saving and emission-reduction, low-carbon (LC).Sbrasive belt grinding is a kind of elasticity mill Cut, multiple effect such as grinding, grinding, polishing can be made, so the wide model of its range, use from familiar daily life The production of product to large-scale aerospace utensil has application.According to 2014 on the coated abrasive tool information technology exchanging meeting that Hubei Wuhan is held Statistics, only 2014 first half of the year, domestic coated abrasive tool yield just reached 2.42 hundred million square metres, and proportion next-door neighbour's sand is occupied in abrasive band, emery cloth class After paper, about 6,000 ten thousand square metres about.Wherein based on the not high abrasive band of some coarse grain, precision, they adopt terylene, The matrix of cotton or polyester cotton blending is made.Therefore tensile strength is low, wear no resistance, and inefficacy abrasive band can be because polyster fibre performance be long Phase is stable, not perishable causes environmental pollution.State Council issues in the recent period《Made in China 2025》, guiding theory proposed five One of item basic principle is Green Development, emphasizes using sustainable development as the important impetus building manufacturing power, and proposition will add Strong energy-conserving and environment-protective technology, develops a circular economy, and improves resource recycling efficiency, builds green manufacturing system, walks conservation culture Road for development.So, abrasive band, emery cloth had two aspects to tend in terms of sustainable development in recent years：One is：Green ring Guarantor's aspect makes breakthrough, solves inefficacy abrasive band recycling problem, it is to avoid pollution environment；Two are：Sustainable development, synthesis is fine Tieing up relied on petroleum resources will be increasingly exhausted, textile fiber material supply breach very big it is necessary to make full use of biomass resource, Crop waste resource and waste textile regenerated resources, open up fibrous raw material New view further.In order to solve the above problems, Scientific and technical personnel's just constantly research and discovery, research and development novel environment friendly abrasive band although technically making some progress, but The technical barrier not yet overcoming is remained in practice.

Content of the invention
