Description
[technical field]
The present invention relates to paint, specifically, relate to a kind of low-surface treatment rusty rust inhibiting primer for hot galvanized steel.
[background technology]
Low surface treatment paint is primarily aimed at and can not reaching sandblast rank Sa2.5 fully, craft or power tool be can be coated in and St2 and other surface of St3 level and the surperficial on rust paint of high-pressure water jet rust cleaning are polished to, active substance in its dependence coating is with the rusty scale passivation and be converted into stable nontoxic filler, realizes low surface treatment; And use the resin of good penetrability that rusty scale is sealed, to reach protection effect.
Pot galvanize is that anticorrosion of steel structure adopts more a kind of anti-corrosion method, is for preventing that surface of steel plate from being corroded, prolong its work-ing life that be coated with layer of metal zinc at surface of steel plate, the steel sheet of this zinc coating is called galvanized sheet, i.e. pot galvanize.But after hot galvanized layer was corroded, when protecting, because the zinc laminar surface can be very low, a lot of coating were in its surperficial poor adhesive force again, and protection effect is subjected to very big influence.
Application number: 200810115543.2, denomination of invention is: the patent of invention of " steel material is embroidered rust-proofing primer and manufacture method with low surface-treated band " discloses: " A liquid is by 1 weight part bisphenol A type epoxy resin; 0.3 weight part dimethylbenzene; 0.3 weight part propyl carbinol; 0.1-0.3 weight part Weibull; 0.1-0.2 weight part process white; 0.1-0.3 weight part zinc phosphate, 0.1-0.2 weight part talcum powder, 0.1-0.3 weight part red iron oxide, 0.01-0.1 weight part dimethyl silicone oil, 0.01-0.1 weight part polyester modification poly phosphate compound, 0.01-0.002 weight parts of polyamide wax is formed; B liquid is made up of 1 weight parts of polyamide resin, 0.3-0.5 weight part dimethylbenzene, 0.1-0.4 weight part propyl carbinol ... "; Studies show that: benzene and benzene series thing can present the anesthetic action of nervus centralis organ systems after being sucked by people's health; The health hematopoiesis effect that can suppress the people is cut down red blood corpuscle, white corpuscle, thrombocyte, and regeneration stagnation deficiency of blood trouble rate increases; Also can cause women's menses unusual, the first person's character defective of fetus etc.
Therefore, the usage quantity of dimethylbenzene is too much in this patent of invention, makes that this priming paint all can be bigger to the harm of environment and HUMAN HEALTH generation after use and use, ignored environmental protection.
[summary of the invention]
