AI Technical Summary

Problems solved by technology

Coating is an important functional protective material. There are few special coatings for fossil anti-aging in the market. At present, it can be brushed on the surface of fossils to prevent fossils from weathering, cracking, breaking, pulverization, and peeling, and reduce fossils from being eroded and damaged. The speed of destruction of the paint has not yet been disclosed

Abstract

A water-based fossil anti-aging paint and a preparation method thereof, which is formed by two components A and B according to the mass ratio of 1:1, and the component A includes the following components and content in parts by mass: acrylic acid 90-120 parts of polyurethane water dispersion, 0.5-1.5 parts of thickener, 5-20 parts of deionized water; in parts by mass, the component B includes the following components and content: propylene glycol methyl ether acetate 2- 8 parts, 0.5~5 parts of dispersants, 0.08~0.15 parts of defoamers, 10~30 parts of deionized water, 10~20 parts of nanometer CaCO3 ultraviolet absorbers, 10~20 parts of nanometer Al2O3 wear-resistant agents; A method for preparing the coating is disclosed. The coating of the invention has water resistance, light resistance and abrasion resistance, and the coating can be brushed on the surface of fossils to prevent weathering, cracking, fracture, powdering and peeling of fossils, and reduce the speed of erosion and destruction of fossils.

Description

technical field [0001] The invention relates to a coating technology, in particular to a water-based fossil anti-aging coating and a preparation method thereof, belonging to the technical field of coatings. Background technique [0002] Fossils are the corpses of ancient organisms buried in the sand, tightly wrapped by the sand, not destroyed and disappeared, but filled with other minerals, retaining its shape and even its internal structure. Under special circumstances, a certain The corpses of some creatures can be preserved intact, such as mammoths in the Arctic tundra, insects in amber, etc. Fossils are historical witnesses, which can help humans understand the development process of the earth's history. However, these fossils were discovered, After being excavated and displayed, they are first exposed to nature. Under photochemical action, the ultraviolet light in the sun has a strong destructive effect on the fossil group. Almost all the excavated and preserved fossils...
