Description
Technical field
The invention is related to paint field, and in particular to a kind of water-based acrylic acid top-coat.
Background technique
Water-base resin category macromolecule subject frontier, foreign countries begin one's study the 1970s, since water-base resin has
There is environmental-friendly, safety be easy to get, be easy for construction, the advantages such as broad covered area, portioned product gradually industrializes at present.Water-base resin
It is to replace organic solvent as the new type resin system of decentralized medium using water, macromolecule resin is dispersed in water, can arbitrarily deploy
It is suitble to the viscosity of processing and forms metastable state liquid, then forms resin bond material after water volatilization in system.Water-base resin is ground
Study carefully the filmogen that emphasis is acquisition excellent physical properties after water volatilization, accomplishes " water-base resin water is insoluble ", overcome aqueous medium band
High surface tension, the high specific heat capacity etc. come are unfavorable for the factor of coating processing.
Water paint can reduce the pollution to environment, many in building, automobile, woodenware, ink, household electrical appliances, fabric etc.
Field application.Currently, utilization rate of advanced country's Environmental Protective Water-paint average service rate up to 80%, 2010 year China has reached
25% and increased with average annual 7% or so speed.It is applied entirely with water paint in the external wall of building coating field, West Europe
Dress, the utilization rate of Singapore are greater than 85%, and beauty, day etc., country was then up to 70~90%: in automotive field, water paint not only exists
It is widely adopted in terms of automotive OEM (genuine paint) coating, and fast-developing in terms of positive car refinishing paint.Currently, the U.S. pair
The exploitation of water paint is more than 50%, and China also attaches great importance to the exploitation of the water paint of low environmental load type.Currently, aqueous
Coating ratio shared in China's paint field is also smaller, mainly there is the reason of the following aspects: first, China is aqueous
The research and development starting of coating is later compared to external, and industrial coating field is very high to the performance requirement of film.Second, due to
Develop difficulty it is larger, current water paint preparation process cost is big, low efficiency, thus the water paint of existing market mainstream its
Price is relatively high, thus fails to be widely used.Third, since water paint development is not yet mature, for secure context
Consider, most enterprises and individuals, which are reluctant to accept the risk, replaces old solvent based coating using Novel water-based paint.With it is molten
Dosage form coating is compared, and water paint research and development difficulty is larger, and preparation process cost is big, and aspect of performance is also not necessarily applied better than solvent type
Material.General water paint slow drying speed, toughness is low, hardness, water-fast, wearability are not good enough.
