Embodiment Construction
[0006] A method for preparing and using a water-curable putty product, characterized in that: the preparation method of the putty product includes the following steps: taking 30-35 parts by weight of an unsaturated polyester resin modified with dicyclopentadiene as the main base material, the structural formula of the resin is Among them, R stands for dihydric alcohol. The water-cooled slag taken from the ironmaking process of steel mills and ferroalloy plants is calcined at 1300-1400°C in a muffle furnace, cooled and ground to 300-400 mesh, and then added with 3-5wt.% Calcium sulfate hemihydrate forms a total of 14.5-25 parts by weight of auxiliary base material. After the main base material and auxiliary base material are fully dispersed in a high-speed disperser at 1500-1800L / min, the auxiliary initiator is gradually added in order 4—5.3 parts by weight, 4—5.5 parts by weight of pore sealing agent, 3—4 parts by weight of adhesion enhancer, 1—1.88 parts by weight of stabili...

The invention discloses a preparation method and a using method of a water curing putty product. The preparation method comprises the following steps: 30-35 parts by weight of unsaturated base resin modified by dicyclopentadiene is taken as a main base material, the main base material, 14.5-25 parts by weight of auxiliary base material prepared from calcined products of water-cooling dregs from a steel mill and an iron mill and calcium sulfate hemihydrates are put into a high-speed dispersion machine and dispersed uniformly, then a certain amount of auxiliary initiator, air hole sealant, stabilizing agent, dispersing agent, filling agent and the like are sequentially added, and after a uniform paste body is formed, the uniform paste body is put into a colloid mill to be milled to obtain a product with the needed fineness. The using method of the putty product comprises the steps of taking 100 parts by weight of paste putty product, adding 10-15 parts by weight of tap water, well water or river water with the pH value of 7-8 into the putty product and then stirring uniformly. The water curing putty product has the advantage of completely meeting related standards, and has outstanding environmental protection performance, safety and economy.
Description
technical field [0001] The invention relates to a preparation method of a water-cured putty product. Background technique [0002] The surface of products in manufacturing industries such as locomotives, automobiles, and motors needs to be decorated, and putty must be embedded in the decorative coating. At present, the commonly used putty in China includes putty putty and epoxy modified putty. Ester putty, polyester putty from PPG company, unsaturated polyester putty from Nippon Paint Co., Ltd., etc., have the common characteristics of fast drying at room temperature, strong adhesion and good construction performance. But the curing agent that they are used is initiator all is organic peroxide. This traditional curing agent emits an unpleasant smell, which is harmful to the health of the operator, and is inflammable and explosive. It is easy to deteriorate during production and transportation and has potential safety hazards. It really needs to be improved. Contents of th...
