Abstract

The invention discloses an algae and calcium containing inorganic ecological coating and a preparation method thereof. The algae and calcium containing inorganic ecological coating comprises raw materials in percentage by weight as follows: 3%-8% of algae, 37%-40% of calcium containing inorganic matrixes, 1.5%-4.2% of environmental mineral powder, 1%-2% of nano titanium dioxide, 8%-12% of silicate excited colloid, 0.15%-0.4% of a retarder, 2.5%-4.25% of a dispersing agent and 30%-41% of deionized water, wherein the percentages of all the components add up to 100%. The silicate excited colloid is taken as a film forming matrix and reacts with active silicon and a calcium source component, the film forming performance, the film strength, the attachment and the wear resistance of the coating are improved, and the coating further has the characteristics of nature, environmental protection, no VOC (volatile organic compounds) pollution, various ecological functionality, simple process and excellent weather resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an algal calcium inorganic ecological coating and a preparation method thereof. Background technique [0002] Now general-purpose coatings (emulsion paints) are composed of four components: (1) film-forming substances: mainly polymer emulsions; (2) pigments and fillers: mainly titanium dioxide, calcium carbonate, pigments, etc.; (3) Water; (4) Auxiliaries: mainly composed of various polymer synthetic organic substances such as film-forming aids, defoamers, thickeners, leveling agents, preservatives, and antifreeze agents. Indoor pollution caused by paints, human health hazards caused by many VOCs (volatile organic compounds) in paints, and the frequent exposure rate of unqualified batches of paints from many brands have long been known. The development of environmentally friendly and resource-saving paints is an important aspect of the paint industry. The mainstream o...
