Abstract
The present invention provides spray modified epoxy phenolic coatings in a kind of food mental package comprising following components in percentage by weight：Modified epoxy fat 70 95%；Phenolic resin 5 28%；Auxiliary agent 0 2%.The present invention also provides a kind of preparation methods of spray modified epoxy phenolic coating in food mental package.The present invention can reduce fossil resources consumption and VOC emission amount and greenhouse gas emissions compared to the prior art, so as to reduce the pollution sources to social environment, respond the environmental protection policy of country.
Description
Technical field
The present invention relates to spray paint in a kind of food mental package, in particular to being sprayed in a kind of food mental package
With modified epoxy phenolic coating and preparation method thereof.
Background technology
As country is increasingly stringenter the improvement of environmental protection, from now on, iterative method Green Development, Speed-up Establishment green are needed
The structure of the law and policy guidance of production and consumption, establish and improve the economic system of green low-carbon cycle development.It leads in structure market
To green technological innovation system, develop Green Finance, grow energy conservation and environmental protection industry, clean manufacturing industry, clean energy resource industry.
Promote production of energy and consumption revolution, structure cleaning low-carbon, safe and efficient energy system.Resource is promoted to save and recycle comprehensively
It utilizes, implements national action of economizing on water, reduce energy consumption, material consumption, realize production system and living system circular linkage.
Canned food special-purpose metal package coating used at present is mainly based on epoxy resin solvent based coating
The coating of body, excellent water-resistance, alkali resistance, chemically-resistant anticorrosive property and good film resist processing are impossible complete
Full substitution.But its main feature is that due to using high molecular expoxy resin (general E-06 or E-03) metal packaging coating afterwards
Solid content can be in 35-38%, so that organic solvent accounting reaches 62-65% in coating, because of existing mental package
Industry is required for baking-curing at a temperature of 180-210 degree substantially, this final part organic solvent is in metal coating process
All by high-temp combustion environmental protection treatment after volatilization, and it will produce the discharge of a certain amount of VOC and the waste of resource inefficiencies.
In addition, using metal packaging coating made of macromolecule epoxy resin during applying print, due to solid content
Limitation causes in high coating thickness technological requirement must to use the secondary technique for applying print and secondary baking is even more could expire
Its coating thickness technological requirement of foot, more primary discharges for applying print and toasting a large amount of waste of energy and increase greenhouse gases.
Invention content
In consideration of it, the present invention provides spray modified epoxy phenolic coating and its preparation sides in a kind of food mental package
Method is reduced with reducing fossil resources consumption and VOC emission amount and greenhouse gas emissions to social environmental pollution source, response
The environmental protection policy of country.
Thus, on the one hand, the present invention provides spray modified epoxy phenolic coatings in a kind of food mental package comprising
