Problems solved by technology

[0003] However, the conventional performance of the putty produced by the existing technology is stable, and the dust falling off in the later stage will cause serious air pollution. The trace chemical substances harmful to the body inside the putty cannot be controlled, and they are released in the air for a long time, which is increasingly unable to meet people's needs for special spaces.

Abstract

The invention discloses environmental-friendly edible grade functional interior wall powder putty and putty cream and a preparation method thereof. The preparation method comprises the following steps: weighing 20-30 parts of food grade rubber powder, 160-200 parts of food grade ground limestone, 800-1000 parts of edible talcum powder, 25-30 parts of edible bentonite, 1.5-2 parts of edible polyacrylamide, 3-6 parts of edible carboxymethylcellulose and 0.5-1 part of a food grade preservative, uniformly mixing, stirring for 10-15 minutes, and discharging to obtain putty powder; adding needed deionized water into the putty powder, thereby obtaining the putty cream. Compared with the prior art, the invention aims to produce the edible functional special putty, and the product is environmental-friendly, convenient and non-toxic, and can be applied to interior wall decoration of biological research rooms, foodstuff factories, infant activity rooms and special people, leveling decoration of special surfaces of packages, furniture and toys and the like; the adhesive property of the wall and later putty film-forming strength are improved, and the impact resistance and cracking resistance are simultaneously improved compared with those of the conventional putty.

Description

technical field [0001] The invention relates to the field of functional putty coating used in special environments in building interiors, in particular to an environment-friendly edible grade functional interior wall putty powder and putty paste and a preparation method thereof. Background technique [0002] Building interior wall putty is a kind of ready-mixed dry powder made of talc powder as filler, cement or lime calcium, 808, 801 glue as cementing material, mixed with some modification additives, stirred by the manufacturer, and mixed. (putty powder) or wet mix (putty paste). It is mainly used for whitening decoration on the inner wall of buildings, and has the advantages of convenient construction and good durability. The putties on the market are mainly cement-based, gray calcium-based dry powder putty powder and 808, 801 putty paste, and the above putty is widely used in conventional building interior wall decoration; but with the development of today's technology, ...
