Natural plant gum waterproof putty

Abstract

The invention discloses natural plant gum waterproof putty which is prepared from the following raw materials in percentage by mass: 0.05-0.15% of hydroxypropyl methyl cellulose, 0.15-0.25% of latex powder, 0.15-0.25% of special putty gum powder, 0.05-0.1% of multifunctional gum powder, 0.3-0.5% of natural starch, 0.01-0.05% of a mildew preventive, 30-50% of ash-calcium-powder, 3-8% of talcum powder, 30-40% of coarse whiting powder and 15-25% of water. Hydroxypropyl methyl cellulose is taken as a framework, and natural starch is taken as a main adhesive, so that the use strength of putty is improved, and at the same time, no harmful gas can be volatilized; after being coated on a wall, the putty is not peeled off, swelled or dropped off, so that the natural plant gum waterproof putty has the advantages of excellent adhesion strength, scrubbing resistance, alkali resistance, crack resistance and the like; the natural plant gum waterproof putty is low in raw material price and applicable to industrial-scale production.

Problems solved by technology

At present, some manufacturers use low prices to participate in market competition, and obtain profits through low-quality putty powder (reducing the amount of rubber powder added or using rubber powder with extremely poor bonding strength), which has led to vicious competition in putty powder. The price of putty powder has been falling all the way. On the other hand, low-quality putty powder affects the construction quality, which makes the putty powder in the whole market more and more suspicious and resisted.

At the same time, the traditional putty powder not only needs to be prepared on site, but also has the problems of poor strength, resistance to scrubbing, water resistance, and mildew, which brings great inconvenience to construction
