Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of waterborne, polycarbonate modified silicasol composite coating and its
Preparation method.
Background technology
The high speed development of science and technology, the raising of productivity allows the material life quality of the mankind to obtain very big lifting, while
Requirement of the people to material life and environment is also more and more high, and world community all begins to focus on environmental issue.Participate in world's ring
The countries and regions for protecting tissue just constantly increase.Environmental issue is the cardinal task of currently all country.Coatings industry is one
The special raw material-intensive industry of individual comparing, many organic coatings in the mill can be using some infringement human body and environment
Raw material, many harmful gases and waste water can be formed aborning, or even in a period of time very long after use, still can
Lasting release pernicious gas, not only the body to people is harmful, and pollution is also caused to environment, wastes resource.Twentieth century
Afterwards, global every country discloses Law on Environmental Protection successively, and these legal norms are discharged into waste water, waste gas and waste residue
Strict limitation is gone, raw materials of some infringement healths and environment are gradually given up in beginning.The development shape of coating industry
Formula is faced with very severe situation, and traditional solvent-borne coating dominance in decades is faced with greatly challenge,
And the environment-friendly type coating such as high solid coating, solventless coatings, powdery paints, water paint and photocureable coating has been subject to vast
The favor of scientific worker, countries in the world all take many manpowers with material resources to research and develop environmental protection coating material.Water paint belongs to
Environment-friendly materials, the harmful substance that it contains is very low, can be ignored, using very safe and easy to use, not by should
With the limitation of occasion, the paint film property of portioned product has reached the paint film property of solvent based coating, and demand is more and more,
The principal item of Coating Market is had become now.But by the end of current, water paint field remains many needs urgently
The problem that must be solved.Therefore the performance of water paint is improved constantly, expands the application field of water paint, accelerate water paint
Development is the important task that we must take on.
Water paint kind is very more, and its demand and solvent based coating are similar, using scope widely, comprising state
The all spectra that family builds, Ludox based waterborne coatings are most potential environmental protection coating materials at this stage.Based on silicon sol solution
Film forming matter, additional pigment, filler, coating additive is wanted to be referred to as through the water paint that high-speed stirred grinding is configured to after dispersed
It is Ludox based waterborne coatings, the performance such as its water resistance, abrasion resistance and anti-pollution is very strong.In the type coating film forming matter
With SiO2For unit is dispersed in water, H2SiO3It is its main molecules form, micelle particle is very small.When glue is analysed, SiO2
Activity it is very high, easily just the fine particle in coating can be bonded very, so it applies in coating maximum
Advantage is exactly do not have back dissolving, also good water resistance.Along with its raw material sources is abundant, cost also than less expensive, it
Itself there are various other premium properties, such as larger specific surface, the high degree of dispersion of adsorptivity solution higher, its
Also there is stain resistant, wear-resisting, with low cost, but when Ludox is used alone, film forming generally occurs and splits under normal temperature
The weak points such as trace, internal capillary, steadiness are poor, paint film bad mechanical property.Therefore Ludox can typically be changed
Property, with the film forming matter as coating, but existing modified silicasol water paint still suffers from following deficiency at present：The
First, poor water resistance；Secondth, filming performance is not good, and fragility is big；3rd, hardness is relatively low.Therefore to modified silicasol water paint
Research is significant.
