Abstract
The invention relates to an anti-corrosion primer for iron and steel, in particular a polyurethane modified epoxy ester bituminous coating. The anti-corrosion primer for iron and steel is composed of a material A and a material B, wherein the material A is adopted as a curing agent and the material B is adopted as a paint film main body. Hydroxy telechelic polyester or polyether, and isocyanate are subjected to a reaction with a solvent for 2-3 hours at a temperature of 80-110 DEG C to prepare the material A. The material B comprises epoxy ester resin, coal tar pitch, talc powder, calcium carbonate, mica powder and functional antirust pigment. During use, the material A and the material B are mixed uniformly in a ratio of 1:2-3 to obtain an anti-corrosion primer for iron and steel, wherein the anti-corrosion primer for iron and steel has advantages of acid and alkali resistance, oil resistance, water resistance, industrial atmosphere resistance, strong adhesion and quick desiccation, and various performance indexes of the anti-corrosion primer reach or exceed a relevant national standard. More importantly, according to the present invention, high-build coating and low VOC emission of the anti-corrosion primer are realized, and purposes of environmental protection and cost saving are achieved.
Description
Technical field
The present invention relates to a kind of steel anti-corrosive base paint, specific field belongs to the chemical paint production technology.
Technical background
Nearly 7,000,000 tons of China's coating gross annual output amount, annual organic volatile (VOC) to airborne release just reaches more than 3,000,000 tons, directly atmospheric environment is polluted, and destroys environment for human survival, the infringement HUMAN HEALTH, and caused the huge wasting of resources.The economic model of this and current renewable Sustainable development is antipathetic, and countries in the world government has all carried out strict restriction to the VOC content in the coating.Therefore, powder coating, the molten material of water-based, solventless coatings, high solid coating have obtained fast development in recent years, at the iron structure system, because powder coating and solventless coatings execution conditions are relatively harsher, and water-borne coatings very easily causes the sudden strain of a muscle rust when construction, and its Corrosion Protection is generally all undesirable after the film forming, thereby has restricted their development in steel surface erosion shield field.
Summary of the invention
The objective of the invention is in order to reduce the VOC discharging of steel anti-corrosive base paint, improving the construction environment of coating in construction provides a kind of high polyurethane pitch coating that contains admittedly, hangs down murder by poisoning, excellent combination property.
The present invention adopts following technical scheme to realize: polyurethane modified epoxy ester bituminous composition, by forming as the A material of solidifying agent with as the B material of paint film main body, wherein the A material is made of the raw material of following weight ratio: hydroxyl telechelic polyester or polyethers 50-70%, solvent 10-50%, isocyanic ester 10-50%, evenly after 80-110 ℃ of reaction promptly obtained the A material in 2-3 hour, the B material is made of the raw material of following mass ratio: filler 0-50% such as epoxy ester pitch material 30-70%, function rust-stabilising pigment 10-50%, talcum powder, lime carbonate, mica powder with above material mixing.
A material of the present invention is 1 with the proportioning of B material: 2-3
Positively effect
The polyurethane modified epoxy ester bituminous composition performance that the present invention obtains meets JG/T224-2007 " construction steel structure protective system " requirement.
Compared with prior art; the present invention combines acid and alkali-resistance, wear resistance, the erosion resistance of sticking power, wear resistance, quick-drying, the epoxy ester of polyurethane material, the water tolerance of bituminous material; by introducing low volatilization isocyanate-monomer and appropriate solvent; realized the highly filled of coating products; thereby the thick filmization of application, low VOC discharging, low poisoning have been realized; reached the protection environment, the healthy purpose of protection workman.This coating products not only is widely used in the attached corrosion base paint of all kinds of ferrous materials, also is applicable to the corrosion protection coating of other metal products.And can be widely used in all kinds of above and below ground waterproofing work, have certain social benefit and economic benefit.
