Problems solved by technology

The putty is atomic ash, which has the following disadvantages: (1) The curing time is too fast, the operating time is about 10 minutes, and the construction performance is poor; (2) It is easy to absorb moisture, which is not conducive to drying, and has high requirements for construction conditions; (3) ) During the construction process, it is prone to sagging, resulting in thin top and bottom thick; (4) When curing, the putty is easy to shrink and crack; (5) After curing, the surface is relatively rough, and it is easy to produce trachoma and air bubbles; (7) Adhesion Poor anti-shock performance, easy to loosen and collapse under strong vibration or impact

Abstract

The invention discloses high-adhesion automobile putty which is prepared from the following components in parts by weight: 350-400 parts of high viscosity polyester resin, 10-20 parts of diisocyanate,50-100 parts of 20-30wt% of shell-lac ethanol solution, 5-10 parts of nano metal powder, 5-10 parts of octadecanethiol 50-80 parts of nano-kaolin, 10-20 parts of magnesium oxide, 20-30 parts of magnesium chloride, 10-20 parts of basalt fibers, 5-10 parts of sodium fluoride, 20-30 parts of styrene, 100-150 parts of talcum powder, 50-60 parts of titanium dioxide, 5-10 parts of cobalt octoate and 200-250 parts of cyclohexanone peroxide. The high-adhesion automobile putty disclosed by the invention is high in adhesive force, high in drying speed, easy in knife coating, excellent in construction performance, smooth, flat and crack-less in appearance after curing and easy to polish. The invention further provides a preparation method of the high-adhesion automobile putty. The preparation methodis simple in process steps and high in operability and does not have special requirement on equipment.

Description

[0001] This application is the application number: 2016101433964, the application date: March 14, 2016, the title of the invention: a divisional application of a high-adhesion automobile putty and its preparation method. technical field [0002] The invention relates to a putty, in particular to a high adhesion automobile putty and a preparation method thereof. Background technique [0003] When defects such as seams, welds, and pits and scratches caused by scratches appear on the surface of the car body, it needs to be filled with putty and carefully polished to form a smooth surface for the final surface spraying. [0004] At present, the commonly used putties include acid alcohol putty, epoxy putty and putty. The drying of acid alcohol putty is greatly affected by drying temperature and humidity, and its hardness is low, and its adhesion is poor, so it is gradually eliminated; epoxy putty uses a large amount of organic solvents to reduce viscosity, resulting in the phen...
