Problems solved by technology

[0003] The traditional putty powder often uses cement as the cement, which inevitably has defects such as shrinkage, cracking, peeling and peeling of the cement base material; and in recent years, people have added carboxymethyl cellulose, carboxy Methyl starch, pre-gelatinized starch, and carboxymethyl starch and pre-gelatinized starch have poor cohesion and mildew resistance. After use, the putty powder is prone to mildew in wet weather. The reason for the easy mildew is The existing paint contains nutrients suitable for the growth of mold. In humid weather, the mold spore powder floating in the air will adhere to the surface of the object and spread rapidly, which can cause human respiratory infection and directly endanger the physical and mental health of the human body. living environment

Abstract

The invention discloses putty powder for interior walls, relating to the field of coatings. The putty powder comprises the following components in parts by weight: 45-70 parts of modified talc powder, 15-30 parts of heavy calcium carbonate, 15-30 parts of sierozem powder, 1.5-2.5 parts of hydroxypropyl methyl cellulose, 10-15 parts of nano-zinc oxide, 2-5 parts of nano-silica, 2-3 parts of rubber powder and 0.5-1 part of pigments. Compared with the prior art, by adding nano-zinc oxide and nano-silica into the putty powder for the interior walls, the production of mycete can be inhibited, and a mildewing phenomenon can be prevented.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a putty powder for interior walls. Background technique [0002] Putty is located between the wall leveling mortar and the paint layer, and plays an auxiliary role in further leveling and forming decorative texture patterns. [0003] The traditional putty powder often uses cement as the cement, which inevitably has defects such as shrinkage, cracking, peeling and peeling of the cement base material; and in recent years, people have added carboxymethyl cellulose, carboxy Methyl starch, pre-gelatinized starch, and carboxymethyl starch and pre-gelatinized starch have poor cohesion and mildew resistance. After use, the putty powder is prone to mildew in wet weather. The reason for the easy mildew is The existing paint contains nutrients suitable for the growth of mold. In humid weather, the mold spore powder floating in the air will adhere to the surface of the object and spread ra...
