Abstract
The invention discloses a production method of a glue for filling the casting silts, and belongs to the field of metal casting processing. The glue is composed of the following components in percentage by weight: 33 to 35% of glycidyl ether epoxy resin, 20 to 22% of epoxy propane butyl ether, 6% of liquid polysulfide rubber, 6% of liquid silicon resin, 3% of epoxy curing agent, 19% of iron powder, 8% of ceramic powder, and 3% of asbestos fiber. The components mentioned above are taken as the raw materials, a chemical reactor and a mixing tank are taken as the production equipment, and a proper temperature and a proper reaction time are controlled so as to produce the glue for filling the casting slits. The production method has the advantages of application of general equipment, simple production technology, and no discharge of wastes or pollutants. The glue is mainly used to repair the iron/steel casting defects, can also be used to repair the defects and slits in metal castings such as aluminum castings, magnesium castings, and the like, and also has a good repairing effect on holes in castings, sand holes, scratches, and oversize.

Summary of the invention
The problem to be solved in the present invention is to provide the production method of a kind of foundry goods gap padding gum, this foundry goods gap padding gum with the glycidyl ether type epoxy resin of liquid state for main raw material, with chemical reaction kettle and blending tank for conversion unit, and be equipped with suitable temperature and the reaction times produces foundry goods gap padding gum, the raw material producing this foundry goods gap padding gum use has: glycidyl ether type epoxy resin 33%-35%, epoxy propane butyl ether 20%-22%, liquid polysulphide rubber 6%, liquid silicone resin 6%, epoxy hardener 3%, iron powder 19%, porcelain powder 8%, fibrous magnesium silicate 3%.
The present invention can be achieved through the following technical solutions:
A production method for foundry goods gap padding gum, its feature is made up of following steps:
(1) the liquid glycidyl ether type epoxy resin of formula ratio is sent into chemical reaction kettle, start stirrer, rotating speed is 25 revs/min, temperature is elevated to 50-60 DEG C, add the epoxy propane butyl ether of formula ratio while stirring slowly, stir the liquid polysulphide rubber, the liquid silicone resin that add formula ratio after 0.3 hour, then stirring reaction stops after 0.6 hour stirring.
(2) material in chemical reaction kettle is sent into blending tank, start to stir after being cooled to normal temperature, rotating speed is 15 revs/min, adds the iron powder of formula ratio, porcelain powder, fibrous magnesium silicate successively, stir the epoxy hardener adding formula ratio after 0.2 hour, after stirring, stop stirring obtaining finished product.
(3) using method of foundry goods gap padding gum is: be injected into after solidifying in foundry goods gap.
Temperature of reaction in chemical reaction kettle described in step (1) is 55 DEG C.
The invention has the beneficial effects as follows: the production method providing a kind of foundry goods gap padding gum, this production method uses general-purpose equipment, simple, the pollution-free waste discharge of production technique, product is mainly except filling up for Iron And Steel Casting defect, also can be used for the repairing of the defect of metallic member such as cast aluminium, casting magnesium and crackle, to the reparation of blow hole, sand holes, scuffing, dimension overproof, also there is good effect.
