The preparation method of Ji Environment-friendlywear-resistant wear-resistant coating.
Background technique
Corrugated board uses over one hundred year by the mankind, by taking China as an example, since nineteen ninety-five, and in short 5 years, China watt
Corrugated paper board annual output reaches 13,000,000,000 sides meter or more from 7,400,000,000 square metres of swift and violent increase.2002, increases respectively within 2003 and reach 141
Hundred million square metres and 15,100,000,000 square meters become second-biggest-in-the-world corrugated board production state.A large amount of uses of the paper products such as corrugated board,
Give timber resources very big pressure, only by taking China as an example, China at least consumes the timber of 1000 ten thousand steres on paper products every year,
This substantially exceeds the annual output of forest.
Therefore researcher actively seeks waste paper cycle articles using channel, to alleviate the status of timber resources scarcity.This
Invention provides a kind of preparation method of wear-resistant paint, multiple with inorganic particulate by the way that corrugated board modification is obtained polyhydroxy fiber
