Description

A kind of water-based stoving paint
Technical field
The present invention relates to a kind of material, more particularly to a kind of water-based stoving paint.
Background technology
Coil coating application Coil Coating Products have become abroad very big industry, and the development of domestic Coil Coating Products in recent years is extremely fast Speed.At present, coil coating technology mainly develops to extra long life, product function and environmentally friendly direction, and promotes coloured silk The technological progress of color coated steel sheet and the continuous expansion of application.
The base material of coil coating has cold-rolled steel sheet, hot-dip galvanizing sheet steel, plated steel sheet, allumen plate and aluminium sheet etc., thick Degree is between 0.1~0.5mm.
In past more than ten years, China colored steel industry from scratch, actual utilization of capacity wretched insufficiency, colored steel industry face Face low-end market excessive competition, and high-end market needs the difficult situation of a large amount of imports.The country is also in coloured painted coat steel plate should During constantly being expanded with field, generally, the demand in market is still vigorous.Coloured painted coat steel plate for building is applied in international color Accounting weight is 60%~70% on laminate market, and China accounts for more than 90%, it can be seen that though application is in extension, building is still It is main users.Production capacity total amount has been higher than desired consumption demand, and high-grade color steel is increasingly by Chinese building material market pro-gaze, family The demand of electricity color steel imparts new function, such as antimicrobial surface increasing year by year.Household electrical appliances are very big with plate market, Refrigerator, air-conditioning, washing machine, refrigerator etc. take very big market, and domestic color steel will capture this market and also need down some work Husband, but market is huge.
Existing coil coating can be divided into three major types:(1) priming paint:Priming paint is divided into polyester-ammonia according to film-forming resin difference Base paint, polyester-polyurethane priming paint, epoxy-amino group priming paint, epoxy-polyurethane priming paint, (2) finish paint:Using oil-free polyester tree Fat.Crosslinking curing uses Amino resin.(3) back paint:Use at the back side of coiled steel plate, can apply or not prime, because This requirement has good adhesive force, though combination property requires, not as good as finish paint height, to adopt with finish paint identical resin manufacture as more It is good.
Despite many advantages, such as increasingly automated, efficiency high, steady quality, organic in coating waves coil painting After baking, Jing collects burning to stimulating food (VOC), and heat utilization ratio reaches more than 97%, is a kind of coating process of environment-friendly type.But It is, because solvent based liquid coating need to consume substantial amounts of organic solvent, as people are to oneself healthy living and the cognition of work Improve, therefore it is one of developing direction of environment-friendly type coil coating to reduce VOC even Diamond Search.
The content of the invention
The invention provides a kind of water-based stoving paint, this kind of product meets country the requirement of good property to Product environment, meets Enterprise's production needs, and can effectively substitute solvent based coating, it is adaptable to various places.
For achieving the above object, the present invention provides following technical scheme:
. a kind of water-based stoving paint, including water-soluble resin 200-300;Water 300-350;Amino resins 50-100;Pigment 150- 200;Styrene 20-40;Wetting agent 0.5-1;Defoamer 1-2;Dispersant 0.2-1.0;Propylene glycol monomethyl ether 5-10;Propylene-glycol ethyl ether 5-10;Levelling agent 1-3.
Further, the molecular weight of the water-soluble resin is in 8000-10000.
Further, the amino resins is half Amino resin, 325 amino resins, Amino resin, butyl ether Change one or more mixing in amino resins.
Further, the pigment is in rutile type titanium white, anatase thpe white powder, organobentonite, ultra-fine barium sulfate One or more mixing.
Further, the wetting agent is alkylphenol-polyethenoxy alcohol.
Further, the dispersant is one or more mixing in sodium salt dispersant, ammonium salt dispersant.
Further, the propylene glycol monomethyl ether is technical grade.
Further, the propylene-glycol ethyl ether is technical grade.
Further, the levelling agent is polyurethane-type levelling agent, acrylic type levelling agent, fluorine carbon levelling agent, organosilicon stream One or more mixing in flat agent.
The present invention has following advantages and characteristic;
It is nontoxic to the person after film curing moisture evaporation using water as dispersant, using water as cleaning agent, can Think that enterprise reduces cleaning cost, substitute organic solvent, and then more reduce organic solvent usage amount.This kind of product is also without weight Metal, is more favorable for health of human body, and its paint film reaches solvent in the indexs such as gloss, shock resistance, solvent resistant, weatherability, hardness Type coating property.In storage, as dispersant, do not fire and do not possess chemism due to using water, stable storing safely may be used Lean on.
