Abstract

The invention provides a high-solid-content white filling putty and a preparation method thereof. The filling putty comprises the components of, by weight: 20-50% of linseed oil, 1.0-2.5% of organic bentonite, 20-35% of heavy calcium, 10-20% of barium sulfate, and 10-30% of rutile titanium dioxide. The high-solid-content white filling putty provided by the invention is a functional product with an excellent environment-protection performance. No arene, ether or ether ester is added in the putty, such that the putty causes no damage to the health of the operator. The putty is not categorized as a hazardous chemical, and is safe and reliable in production, transportation, and application. The putty provided by the invention can be applied in a scraping smear process. The putty is characterized by low smell, high solid content, high filling property, and the like. The putty satisfies the requirements of HG / T3356-2003 on various nitrocellulose putty products.

Description

technical field [0001] The invention belongs to the field of fillers for coatings, in particular to a white filling putty with high solid content and a preparation method thereof. Background technique [0002] Putties are generally composed of binders, polymers, fillers and additives. The commonly used polymers in existing putties are aromatic hydrocarbons, alcohol ethers or ether esters to adjust viscosity. For example, trimethylbenzene is used to adjust the viscosity. After the putty is coated, it has a strong smell and causes environmental hazards with the volatilization of benzene solvents. [0003] With the improvement of material living standards, consumers have higher and higher requirements for coating products. According to relevant research reports, contemporary consumers have more comprehensive requirements for the functions of coatings. Coating products with excellent properties such as health, environmental protection, and deodorization are becoming more and mo...
