Abstract

A finishing agent is prepared from the following components: deionized water, hydroxyethyl cellulose, a bactericidal preservative, silica sol, a water repellent agent, a finishing emulsion, a hardening agent, a pH regulator and a wetting agent. The preparation method of the finishing agent comprises the following steps: adding 70% of deionized water into hydroxyethyl cellulose, conducting stirring for 30-60 minutes, conducting full dissolving, adding an antiseptic bactericide, and uniformly conducting stirring; sequentially adding silica sol, a water repellent agent and a wetting agent, uniformly conducting stirring, and adding a pH regulator to adjust the pH value; then sequentially adding the finishing emulsion and the hardening agent, and uniformly conducting stirring; and finally, integrally conducting stirring for 20 minutes. According to the invention, the oleophobic and antifouling effects of the finishing agent are greatly improved while the finishing agent is ensured to have outstanding waterproof performance and sound absorption performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a covering agent. Background technique [0002] The finish is an excellent weatherability, gloss, decorative acrylic system. It can effectively improve the durability and beautification effect of the permeable concrete surface. The color is adjustable, it has good weather resistance and strong wear resistance. It can be used in outdoor environments for a long time. Construction is simple. [0003] There are various deficiencies in many surface covering agents, especially waterproof performance, sound absorption performance, oil repellency, and antifouling effects cannot be combined at the same time. [0004] Therefore, the development of a new covering agent not only has urgent research value, but also has good economic benefits and industrial application potential, which is the driving force and basis for the completion of the present invention.
