Problems solved by technology

Building materials mainly based on cement-based organic waterproof mortar have become one of the most important materials today. The stability of high molecular polymers in cement mortar has been paid more and more attention, especially the high molecular Ultraviolet radiation is a very prominent problem. The high molecular weight polymer in cement mortar is exposed to ultraviolet radiation 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 taken There are many ways to solve 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 cement mortar, these anti-ultraviolet protective agents do not fully play a good role in the cement mortar system

Embodiment 1

[0031] formula:

[0032] 100 parts of gelatin solution with a weight concentration of 1%, 10 parts of copper sulfate, 1 part of sodium hydroxide, 10 parts of thiourea, 20 parts of cyanine light-absorbing dye aqueous solution of 3.3'-diethyloxycarbocyanine iodide salt with a weight concentration of 1‰, by weight 10 parts of 10% stannous chloride ethanol solution;

[0033] Preparation:

[0034] Stir the gelatin solution in a mixer for 20 minutes, then raise the temperature to 65°C, and then add copper sulfate; 5 minutes later, add sodium hydroxide to make the glue turbid, and 5 minutes later, add thiourea to make the glue change. Become transparent, obtain glue solution;

[0035] Add 3.3'-diethyloxycarbocyanine iodide salt cyanine light-absorbing dye solution and tin protochloride ethanol solution to the glue solution. After 30 minutes, change the lighting to an incandescent lamp (without ultraviolet light), and then add Stannous chloride ethanol solution, after 10 minutes, a...

Abstract

The invention discloses a cement-based waterproof mortar photosensitive ultraviolet resistance protectant and the protectant comprises the following components in parts by weight: 100 parts of gelatine water solution, 10-20 parts of copper sulfate, 1-2 parts of sodium hydroxide, 10-20 parts of thiourea, 20-30 parts of 3,3'-diethyloxacarbocyanine iodide merocyanine light-absorbing dye water solution and 10-20 parts of stannous chloride ethanol water. The invention protects the inner layer of mortar, protects the high polymer and pigment from the direct ultraviolet radiation and eliminates the surface chalking and skin peeling of mortar and the decolorization of the pigment.

Description

technical field [0001] The invention relates to a photosensitive anti-ultraviolet protective agent for waterproof mortar. Background technique [0002] With the continuous development and progress of human society and continuous economic growth, my country is undergoing large-scale economic construction, and the demand for building materials is huge. It has been more and more widely used in the construction industry. After the 20th century, the development of building materials has entered a new era. A group of chemical building materials based on organic materials have sprung up, and some new building materials with excellent performance and special functions Appeared one after another, penetrated into all aspects of the construction industry, and became a symbol of modern architecture. The emergence of new materials will inevitably bring new problems, and new problems must be solved by new technologies. Building materials mainly based on cement-based organic waterproof mor...
