Abstract

The invention relates to a preparation method of an environmentally-friendly scratchproof suede-like coating, and belongs to the technical field of coatings. Pores of the environmentally-friendly scratchproof suede-like coating are filled with limestone powder to improve the interface structure and facilitate interface bonding, so the wear resistance of the environmentally-friendly scratchproof suede-like coating is improved; carbon fibers can improve the compressive strength of the environmentally-friendly scratchproof suede-like coating, because the carbon fibers have remarkable reinforcingand toughening effects; the high tensile strength of the carbon fibers limits the development and penetration of cracks in order to achieve strengthening and toughening effects, so the strength of theenvironmentally-friendly scratchproof suede-like coating is improved; and when the wearing leads to cracks, the fibers cross the cracks to transmit the load and alleviates stress concentration at thetips of the cracks, so the stress distribution tends to be uniform, and the crack propagation is effectively controlled, thereby the wear resistance of the environmentally-friendly scratchproof suede-like coating is enhanced.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly, scratch-resistant and hand-feeling coating, which belongs to the technical field of coatings. Background technique [0002] With the improvement of people's awareness of environmental protection, water-based coatings are accepted by more people as a more environmentally friendly coating material, and the prospects for water-based coatings are getting better and better. Water-based paint uses water as a solvent, saving a lot of resources. Water-based coatings eliminate the risk of flooding during construction and reduce air pollution. Water-based coatings only use a small amount of low-toxic alcohol ether organic solvents, which improves the working environment and has a significant effect on reducing pollution and saving resources. [0003] Therefore, at present, various electronic or electrical products, such as digital cameras, notebook computers, mobile phones, etc., have be...
