Abstract
A high performance unsaturated polyester putty for automobile. The invention relates to an elastic putty, which is prepared from unsaturated polyester putty and an initiating agent according to the proportion of 50:1. The unsaturated polyester putty is mainly composed of, by weight, 34-38 parts of unsaturated polyester resin, 4-7 parts of styrene, 0.7-1.8 parts of a promoter, 0.8-1.5 parts of an anti-settling agent, 1-2 parts of a thixotropic agent, 5-7 parts of titanium dioxide and 49-54 parts of talc powder, wherein an initiator is a 10% cyclohexanone peroxide paste. The elastic putty provided by the invention has good dryness and long operable time in the painting process, and has very strong adhesion and flexibility when coated on the surface of the automobile; and the putty does not shed or crack when strong external shock is applied on automobile.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of automobile-used high-performance Unsaturated polyester putty.
Background technology
Atomized ash is a kind of pointing material, and formal name used at school is polyester putty, is mainly used in filleting before application of metal, non-metal material surface, fills and leads up, in the hope of smooth, smooth outward appearance.Atomized ash is take unsaturated polyester as main body, is that with the difference of existing other synthetic resins putty it can regulate curing speed with solidifying agent, and can fast setting.At present, the application market of atomized ash maximum is mainly automobile making and overhaul industry, along with the development of domestic automobile industry, and the competition between industry, visual appearance is more noticeable, also more and more higher to the requirement of atomized ash quality.
But, the atomized ash of selling on market, the shortcomings such as ubiquity hardness is large, rigidity is strong, lack snappiness or snappiness poor, once there is larger contraction in the position of the atomized ash of application, or while being subject to larger external impacts, can not there is not obscission by force because of snappiness and sticking power, greatly affect the visual appearance of automobile.And dryness can not effectively be mated with operability, the operating time that dryness is good is short, and the operating time dryness of length is poor.
