A kind of water paint and preparation method thereof
Technical field
The present invention relates to paint fields more particularly to a kind of water paint and preparation method thereof.
Background technique
It as the saying goes " three points of coating seven give work ", coating products performance has extremely important shadow for the application property of coating
It rings.In the work progress of coating, due to the difference of form of construction work, it is larger to will lead to final coating performance difference.Therefore, it is producing
When product are constructed, often there are many limitations to want construction environment, water quality requirement, the requirement of construction personnel's profession, skill requirement etc.
It asks, in the case where not being able to satisfy water paint above-mentioned requirements, the property of expected effect and film is not achieved in the coating after construction
Energy level results in product failure, schedule delays in this way and spends a large amount of rework cost.Therefore, existing commercially available coating
The bad practical problem of generally existing workability.
As water paint application property individual demand is constantly expected in market, water paint type in continually developing,
Its construction method is also not necessarily limited to water paint concerned countries, and to standard, (" synthetic resin emulsion interior wall applies such as GB/T9756-2009
Material ", GB/T9755-2001 " exterior wall coating material of synthetic resin emulsion ") in brushing mode.And the application property and product of water paint
Viscosity, storage period, shear viscosity, pH value and construction personnel, the factors such as construction environment have a relationship, and above-mentioned each factor it
Between there are reciprocation and effect it is significant.
In addition, water paint currently on the market generallys use hydroxyethyl cellulose as system thickener, dissolved
Requirement of the journey to pH value is stringent, and generating a large amount of mushroom vulnerable to the pollution of water quality in production process causes final products rotten.
Therefore, a kind of water paint that application property is splendid how is developed, can satisfy the individual character construction demand of DIY,
It is not limited when constructing by various factors, and the film performance after construction is excellent, is this field scientific research personnel skill urgently to be resolved
Art problem.
Summary of the invention
Technical problem solved by the invention is to overcome existing water paint by application property condition that (such as product is glued
Spend, be watered the factors such as ratio, pH value and construction personnel, construction environment) limitation, the bad defect of workability provides one
Kind water paint and preparation method thereof.Water paint of the invention not only assigns the decoration and defencive function of coating, meets country
Requirement to the related harmful substance standard of water paint, and its form of construction work is not limited to water paint concerned countries to standard

Effect example
To the water paint of Examples 1 to 3, commercially available water paint H1000, water paint BC-200 and comparative example
1 water paint carries out every experiment of performance and environmental protection index, and concrete outcome is shown in Table 5 and table 6.
Each product performance index of table 5
6 environmental protection index of table
As seen from Table 5, the performance of water paint of the invention is stablized, long time without deposit phenomenon, service performance
Good, drying time is fast, and alkali resistance, brushing resistance, stain resistance and temperature-change resistance are good, and artificial weathering ageing resistance is good, and excellent
The water paint made from commercially available water paint H1000, water paint BC-200 and comparative example 1.In addition, to embodiment
It is found in the detection of 1~3 water paint, in the case where pH is 5~10 test condition, the viscosity of each water paint is unaffected,
When pH is less than 4 and greater than 11, viscosity has slight variation.In the range of pH is 3~11, viscosity maxima and minimum value phase
Difference is less than 10%.Based on this, water paint of the invention wants the not stringent soda acid processing of construction substrate in construction
It asks.
As seen from Table 6, the VOC content of water paint of the invention is far below conventional water paint, and trip is not detected
It is a kind of environment-friendly water-based paint for meeting current generation demand, indices from formaldehyde, benzene, toluene and heavy metal substance
It is superior to water paint made from commercially available water paint H1000, water paint BC-200 and comparative example 1.
To the water paint of Examples 1 to 3, commercially available water paint H1000, water paint BC-200 and comparative example
1 water paint it is different using temperature and being watered carry out under ratio viscosity, pH value variation and can construction method test,
It the results are shown in Table 7.Wherein, storage viscosity is tested according to the method in GB/T9269-2009, but temperature when test is practical
Temperature.Wherein, working viscosity is tested according to the method in GB/T9269-2009, but temperature when test is actual temperature,
And revolving speed is 400r/min when testing.
The viscosity of 7 water paint of table, pH value, can workability test result
As seen from Table 7, commercially available water paint H1000, water paint BC-200 and comparative example 1 are then with using temperature
It spends, be watered the variation of ratio and the variation of viscosity and pH value occurs, identical product cannot be real simultaneously after causing condition to change
Brushing, roller coating, spraying, knife-coat application mode are applied, is not able to satisfy the individual character construction demand of DIY.
The viscosity of water paint of the invention with being watered ratio, had almost no change using temperature, and can be used brushing,
The modes such as roller coating, spraying, blade coating are constructed, and pH value not with the ratio that is watered, temperature variation and change, can satisfy
The individual character construction demand of DIY, overcoming commercially available water paint, (viscosity of such as product, storage period, shearing are viscous to application property condition
Degree, pH value and construction personnel, construction environment) limitation.
