Problems solved by technology

Aiming at the existing problems of existing wall leveling materials such as too heavy construction feel, very laborious application, slow construction speed and easy sagging, the applicant of the present invention has developed a putty that can improve the performance of gray calcium-based or cement-based interior and exterior wall putty. slip agent, and applied for an invention patent to the State Intellectual Property Office on April 9, 2013 and was authorized. The patent number is ZL201310121217.3. The slip agent is composed of calcined kaolin, 20-40% hydroxypropyl starch ether and 2.0-6.0% polyacrylamide are uniformly mixed; since this slip agent is in powder form, it is suitable for pre-adding to powdered lime-calcium-based or cement-based putty Stir the material evenly and then add water to adjust it. Due to the limitation of construction site conditions, most of the wall leveling materials for on-site construction are prepared in the factory or mixed with water. Putty paste or construction glue, and some two-component walls The surface leveling material should be mixed and stirred at the construction site when it needs to be used. The above-mentioned powdery slip agent is not suitable for adding to this kind of wall leveling material. In addition, the price of this powdery slip agent is also relatively high. High, the cost of wall leveling materials will be high after adding

Abstract

The invention provides an additive for improving construction performance of wall leveling materials. The additive is composed of, by weight, 0.2-0.5 part of polyacrylamide, 30-50 parts of soft soap, 20-40 parts of liquid paraffin and 9.5-49.8 parts of water. The additive is prepared by the following method: (1) dissolving polyacrylamide in water, placing the solution in a high-speed disperse mixer and stirring at the rotating speed of 800-1,000 r/min for 15 min; and (2) adding soft soap and liquid paraffin, and continuously stirring for 20 min. The additive has advantages of reasonable formula and simple preparation. Cost of the additive is only 1/3 of cost of a powdery additive. With a small addition amount of the additive, smoothness, coating property and sag resistance of wall leveling materials such as putty cream or building glue, etc. can be greatly improved. In addition, strength after hardening is raised, and construction efficiency and wall strength are better enhanced.

Description

technical field [0001] The invention relates to an auxiliary agent, in particular to an auxiliary agent for building construction, and more particularly to an additive which helps to improve the construction performance of leveling materials for internal and external walls of buildings. Background technique [0002] In the field of indoor and outdoor decoration, a variety of wall leveling materials are applied, such as putty, putty paste and construction glue, etc., which are indispensable leveling materials in architectural decoration projects. Construction performance is an important factor in judging wall leveling materials. The construction performance of such materials directly affects the feel of the product, the construction efficiency of workers and the speed of construction. Aiming at the existing problems of existing wall leveling materials such as too heavy construction feel, very laborious application, slow construction speed and easy sagging, the applicant of th...
