High-solid environmental-protection surface patching paint and production method thereof

Abstract

The present invention relates to an one package high-solid environment-protecting type surface repairing paint and its production method. Said repairing paint is made up by using nitro-cotton and alkyd resin as film-forming substance, using acetone, ethyl acetate and butyl acetate as solvent, adding filling material and plasticizer, mixing them and using diluting agent to regulate viscosity. Said repairing paint has a certain flowability, specially has good affinity with wood, can be infiltrated into the wood grain or filled into the indentation of wood surface so as to implement the goal of repairing surface defect of wood product and obtaining flat and smooth wood surface.

Description

Technical field [0001] The invention relates to a nitro coating composition, and more specifically relates to a high-solid environment-friendly surface repair paint and a production method thereof. Background technique [0002] In the production process of wooden pencils, the surface of the wooden pen holder will inevitably have some defects such as uneven wood grains or even dents, which will result in a certain amount of defective product loss. The amount of this loss is considerable over time. It increases the cost of the product, wastes human resources and pollutes the environment. And this kind of worn-out defective pencil is only a surface defect, which does not affect the use function of the pencil itself.

[0002] In the production process of wooden pencils, the surface of the wooden pen holder will inevitably have some defects such as uneven wood grains or even dents, which will result in a certain amount of defective product loss. The amount of this loss is considerable over time. It increases the cost of the product, wastes human resources and pollutes the environment

And this kind of worn-out defective pencil is only a surface defect, which does not affect the use function of the pencil itself. However, if the traditional putty is used to repair the defect on the surface of the wooden pen holder, it is difficult to achieve because the putty has no fluidity, and the traditional The advanced putty process requires multiple processes such as filling, embedding, scraping, sanding, etc., so that it can be repaired one by one, and the laborious work is not worth the candle
