Abstract

The invention discloses a preparation method of good sanding performance putty. The putty is prepared by mixing and reacting a main agent with a curing agent according to a mass ratio of 100:2. According to the invention, components of the putty are optimized to obtain an optimum content ratio of the components, so a very excellent sanding effect, which is characterized in that the putty does not stick sand paper during sanding and the sanded putty is finished and smooth and has no honeycombs, is achieved. To counter the designed components, the method of the invention selects a procedure that the components are mixed step by step, and the components are added in a batch mode according to performances of the components, so the uniformity and the stability of performances of the prepared main agent are guaranteed.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for preparing atomic ash with good grinding performance. Background technique [0002] Atomic ash is mainly used for repairing and painting primers of various vehicles, machine tools, ships, instruments, instrument shells and furniture. At present, the production technology of atomic ash is basically mature, and whether the atomic ash is easy to polish after forming a film has become an important issue. It is an important index to evaluate the product quality of putty manufacturers. [0003] At present, in order to improve the grinding performance of putty after film formation, many manufacturers have adopted various methods: for example, reducing the viscosity of unsaturated polyester resin, while reducing the viscosity of the resin, the risk is high, and it is easy to reduce the activity of the resin. Even putty film formation and cracking; some add mono-acid or fumar...
