Description
Technical field
The invention belongs to the research and development technology field of water paint, and in particular to a kind of raising alkyd resin water paint durability
Method.
Background technology
Compared with traditional coating, water paint replaces organic solvent with water, has the advantages of nontoxic, environmentally friendly, with
The pressure of environmental protection policy, the continuous lifting of consumer's environmental consciousness, provinces and cities especially in all parts of the country have put into effect VOC emission limitation mark
Standard, encouragement use non-solvent coating, and the development to environmental protection coating materials such as water paints brings opportunity.Although traditional coating still accounts for
According to the larger market share, but water paint is pollution-free industry, is the direction for painting class future development.The development of water paint and
The shared market share has been undisputable fact increasing year by year, and has the trend of speed-raising.Some enterprises have appreciated that
The wide market potential of water paint, research and develop, march one after another, expanding water paint market.
Alkyd resin water paint is to use relatively broad a kind of coating, although water paint superior biography on environmental-protecting performance
System paint, but in physical property, the presence construction of water paint product is difficult, not water-fast, easily takes off poor, difference of hardness of skin, richness etc.
Defect.Paint is tolerant due to having the characteristics that strong hardness, paint film richness height, construction, when being still many people's decorations
Preferred coating.Only the defects of physical property is resolved, or even beyond tradition paint, consumer just can more actively select
Use water paint.Only consumer is catered on environmental-protecting performance, consumer can not be met on construction technology, decorative effect,
The market of water paint is difficult still to open.This needs water paint manufacturing enterprise to do technological innovation in water paint performance.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of side for improving alkyd resin water paint durability
Method, the pliability and lower temperature resistance of alkyd resin water paint can be adjusted, prevents coating from occurring during storage and use
The problems such as corruption comes off.
The present invention is achieved by the following technical solutions:
A kind of method for improving alkyd resin water paint durability, method comprise the following steps:
