Problems solved by technology

However, the impermeability pressure of cement-based waterproof mortar and the later flexural strength of waterproof mortar and the stability of polymers in cement mortar have been paid more and more attention, especially the resistance of polymers to ultraviolet radiation is a very important issue. The outstanding problem is that the high molecular polymer in the cement mortar is exposed to ultraviolet light for a long time, and it is prone to fission, which will cause the surface of the mortar to pulverize and peel off, cause the pigment to fade, and cause the performance of the mortar to be affected. People have adopted a variety of methods to solve it. This problem, such as adding a variety of anti-ultraviolet protective agents to the mortar for protection, but due to the influence of the strong alkali system of the cement mortar, these anti-ultraviolet protective agents do not fully play a good role in the cement mortar system

Abstract

The invention discloses an ultraviolet resistance mortar composite and the composite comprises the following components in parts by weight: 400-600 parts of white cement, 50-100 parts of semi-hydrated gypsum, 200-400 parts of heavy calcium carbonate, 200-300 parts of barium-titanium organic composite emulsion and 10-30 parts of photosensitive ultraviolet resistance protectant, wherein the barium-titanium organic composite emulsion is a barium-titanium mixture modified with (methyl) acrylate and (methyl) styrene and the photosensitive ultraviolet resistance protectant is a peptizing agent containing light-absorbing dye, reductant and oxidation complex system. The invention protects the inner layer of the mortar and protects the high polymer and pigment from the direct ultraviolet radiation; the multifunctional ultraviolet resistance mortar composite of the invention can be used as vaious waterproof coatings by adjusing the dosage of the barium-titanium organic composite emulsion and ismainly used as the water resistance mortar of the wall surface of the balcony and the roof for high grade houses.
