Description
Technical field
The invention belongs to coating industry technical field, relate to a kind of water paint, particularly relate to a kind of wear-resisting aqueous and be coated with
Material and preparation method thereof.
Background technology
Coating, at the entitled paint of Chinese tradition, refer to coat body surface can form thin film under certain conditions and
Play protection, a class I liquid I of decoration or other specific functions (insulation, antirust, mildew-resistant, heat-resisting etc.) or solid material.Because of early stage
Coating is mostly with vegetable oil as primary raw material, therefore also referred to as paint.Synthetic resin instead of vegetable oil now, therefore is referred to as being coated with
Material.Coating belongs to organic chemical industry's macromolecular material, and the film formed belongs to macromolecular compound type.Current according to the modern times
The classification of chemical products, coating belongs to fine chemical product.Modern coating the most progressively becomes a polyfunctional engineering of class
Material, is an important industry in chemical industry.
At present, the coating industry of China is the most ripe, and market is close to saturated, in addition in the overall situation of green economy globalization
Under, people become more concerned with economy the most flourishing after, environment is by great destruction.Along with new " environmental law " promulgates, country is " green
Environmental protection, beautiful China " etc. environmental protection advocate the most no longer to stay on slogan, but implement to perform, implement to promote energetically green
The development of color science and technology industry.Traditional coating is one of important sources of air major pollutants VOC, by the aqueous of environmental protection
Paint replacement paint is the most imperative.Compare traditional paint, and water paint is the one of environment-friendly type paint, and it saves oil
Coal resources, and free from environmental pollution, it is to guide consumption to realize energy-saving and emission-reduction.2015, China's Coating Market sales volume 15,000,000
About Dun, the industrial paint accounting by 70% converts, and paint consumption then reaches ten million ton, not only wastes 5,000,000 tons of energy, crucial
It is to cause 5,000,000 tons of toxic and harmful discharges to air.Paint consumes the energy and pollutes environment, and it is big row in the common people consume
Its road, runs in the opposite direction with national energy consumption revolution requirement and guide.Along with the enhancing of people's environmental consciousness, water paint will
Being widely used, research and development water paint has the biggest economic benefit and social benefit.Existing water paint can
To apply the application in industries such as pharmacy, food, hospital, weaving, chemical industry, electronics.Water paint from raw material sources to produce and
The Life cycle used, the most beneficially sound development of environment.It is the most in process of production by volatile organic solvent
Substitute, and when using, coating tool can wash by water, and decreases the consumption of cleaning solvent.The production of organic solvent needs to disappear
Consumption fossil feedstock, is a major challenge to resource in the present stage of resource scarcity, and the appearance of water paint solves this and asks
Topic.Meanwhile, the reduction of solvent, greatly reduce the discharge of VOC during producing and using, for improving week
Limit atmospheric environment has made positive contribution.
Country curbs environmental pollution severely, and national environmental consciousness promotes, consuming behavior changes, the sealing wax coating of energy-conserving and environment-protective
Industry is just welcoming unprecedented opportunity to develop, and market presents " blowout formula " Requirement.Efforts To Develop basic research, reduces
The difficulty of construction of water paint, improve serviceability, be water paint expansive approach field, extensive popularization and application when business
Anxious.Meanwhile, strengthen policy guides, promotional technique, transformation concept, the elimination public the prejudice of water paint and misgivings etc.
The attention of related work, also will play the effect of promotion to the application development of water paint.As Green Product, aqueous is coated with
Material necessarily obtains the accreditation of people and is widely used.Before the market demand huge in the face of water paint and ever-increasing application
Scape, strengthens research and development capabilities, and updates and promote the properties of product of water paint, accelerates product quality upgrading, develops in skill
The water paint more showing powerful competitive advantage in art, on cost, in performance has the meaning of reality and wide market
Space.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of wear-resisting water paint and
Preparation method, this coating products excellent performance, there are good anti-wear performance, and energy-conserving and environment-protective, possess preferable economic benefit
