Abstract
The invention discloses putty glue which is prepared by mixing and compounding PVA (polyvinyl alcohol), CMC (carboxy methyl cellulose) and PAM (polyacrylamide), and the putty glue is prepared from the following substances in parts by mass: 2.7-3.0 parts of PVA; 0.3 to 0.55 percent of CMC (Carboxymethyl 0.025 to 0.1 part of 3 million PAM (Polyacrylamide); 0.3 to 0.5 part of 8 million PAM (Polyacrylamide); 0.03 to 0.05 part of PAM (Polyacrylamide) of 16,000,000; 0.01 part of a retarder; 0.2 to 0.3 part of preservative; 0 to 0.01 part of a defoaming agent; and 96.5 to 95.5 parts of water. Compared with the prior art, the invention has the following advantages: the production process is simple, the use of formaldehyde in acetal glue is changed, the problems of difficult temperature rise and temperature control in acrylamide polymerization and poor polymerization stability are solved, the production energy is saved, and the invention also provides the preparation method which is simple and easy to implement, and is easy for mass production and popularization.
Description
technical field [0001] The invention relates to the field of building materials, in particular to a putty glue and a preparation method thereof, which changes the use of formaldehyde in acetal glue and changes the environmental protection and safety of acrylamide glue production. Background technique [0002] Putty glue is composed of PVA, sodium carboxymethyl cellulose, polyacrylamide and external additives, etc. After being stirred with talc powder, gypsum, or a mixture of talc powder and white cement, it has good plasticity and batch scraping properties. It is an excellent building material for leveling and scraping walls with the advantages of high strength, high strength, and labor-saving construction. It is an ideal material for scraping walls in large supermarkets, shopping malls, parking lots, factory workshops, warehouses, and interior decoration. It is the first choice for wall construction in modern buildings. Mainstream materials, formaldehyde-free, broad market ...
