Cold sol powder of inner wall putty

Abstract

The invention discloses cold sol powder of inner wall putty. The cold sol powder comprises the following components in percentage by weight: 80 to 85 percent of plant modified polymer gel powder, 8 to 12 percent of re-dispersible latex powder and 5 to 10 percent of carboxymethyl corn powder. The cold sol powder of the inner wall putty mainly substitutes polyvinyl alcohol glue solution and various additives, and plays a role of adhesive, additive and the like; and field blended and water blended products are prepared according to the sequential adding order of calcium carbonate and water. The cold sol powder of the inner wall putty can be prepared into a dry powder putty adhesive product, and only needs to be mixed with the water and the calcium carbonate in field construction; and the cold sol powder also can be used as a production raw material of a putty powder factory and directly used without adding other auxiliary agents. Therefore, the cold sol powder of the inner wall putty has the characteristics of simple process, no formaldehyde pollution, low cost, good construction performance and high bonding strength, and is easy to blend.

Description

technical field [0001] The invention relates to a putty rubber powder, in particular to a cold sol putty powder for interior walls. Background technique [0002] Putty is a decoration material for repairing and leveling the wall to achieve a smooth and delicate effect. It is mainly composed of filler (calcium carbonate), binder (glue or powder), solvent (water or other solvents) and additives (auxiliary). At present, the putty materials used for decoration mainly include on-site mixed type (such as polyvinyl alcohol urea-formaldehyde glue + calcium carbonate powder + cooked rubber powder, etc.), finished water and type (putty powder + water), etc. [0003] Among them, the on-site mixing type needs to add polyvinyl alcohol + water and add polyacrylamide, formaldehyde, urea, etc. to boil at high temperature to make glue (some manufacturers specially make glue products for sale), and then use glue and calcium carbonate, etc. The materials are mixed into paste putty constructio...

Problems solved by technology

The defect of commonly used tapioca starch is that although it has a bonding effect, if the amount added is large, it will affect the construction performance of the putty powder, and it is not easy to scrape. If the amount added is small, the bonding strength (adhesion) will be low and cannot meet the requirements. It is beneficial for compounding; corn starch has little effect on the bonding strength. The putty powder made of these two materials either has a short service life, is easy to be hollowed out, or has poor construction performance, etc.
