Abstract

The invention discloses a high-temperature-resistant hybrid modified styrene-acrylic emulsion cement coating material and a preparation method thereof. The preparation method comprises the steps: mixing and dispersing nano silica sol, styrene, butadiene, acrylate, a stabilizer and an emulsifier, adding an initiator into a system to prepare modified styrene-acrylic emulsion, and mixing an unsaturated polyester resin microemulsion, the modified styrene-acrylic emulsion, a stabilizer, styrene and butadiene to prepare a hybrid modified styrene-acrylic emulsion; and mixing cement, quartz powder, the modified styrene-acrylic emulsion, a light curing agent, a thickening agent and a water reducing agent to prepare the high-temperature-resistant hybrid modified styrene-acrylic emulsion cement coating material. The high-temperature-resistant hybrid modified styrene-acrylic emulsion cement coating material prepared by the invention has excellent film-forming property, compatibility and storage stability; a coating film has the characteristics of stain resistance, water resistance, alkali resistance, weather resistance and the like, and the high temperature resistance and the mechanical property are greatly improved; and the application range is greatly expanded.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a polymer cement coating, in particular to a high-temperature-resistant hybrid modified styrene-acrylic emulsion cement coating and a preparation method thereof. Background technique [0002] With the development of my country's construction industry and the improvement of people's living standards, architectural coatings have emerged rapidly, and have now developed into an important branch of my country's chemical construction industry. With the rapid growth of architectural coatings production, the industry has made great progress in product structure, technical level, application services, etc., but there is a certain gap in technology compared with advanced industrialized countries, mainly in: construction Most of the additives used in latex paint rely on imports, and there are relatively few high-performance and functional paint products. [0003] In my country, the concentr...
