Description
Technical field
The present invention relates to paint field, and in particular to one kind prepares high performance outer wall paint using orthonormal design of experiments analysis
Method.
Background technology
Exterior coating, it is a kind of outer layer ornament materials for playing the effects such as attractive in appearance and protection brushed outside building.Now,
Exterior coating is widely used, due to its have in use abundant Color Expression effect and its decoration painting face
On can show flexible and changeablely it is various decoration styles and liked by broad masses.In addition, exterior coating also has
The advantages that easy construction, proportion are small, security performance is high and be attractive in appearance.Exterior coating is just gradual with the speed being exceedingly fast now
Substitute the exterior wall finish materials such as traditional mudstone brick and tile.However, exterior coating also encounters some problems when China promotes.By
There is the climatic environment situation of complexity in China, exterior coating occurs that some weather resistances are poor in use, adhesive force
It is low, it is easy to aging the problems such as.The presence of these problems can turn into the huge difficult problem for restricting China's exterior coating industry development.Exterior wall applies
The product quality of material is determined by the performance indications of the physical properties index of itself and resistance external environment condition.This its
In main factor be resistant to weatherability performance indications in external environmental factor, the index high degree Shangdi generation in fact
The table real use value of the coating.The aging of coating can cause the failure of properties of product, influence protection and U.S. of building
Effect is seen, it is not reached expected condition requirement.At present, having various exterior coatings every year, there is due to weather-proof
Poor performance and the phenomenon for causing coating aging.Therefore, the weather resistance for improving exterior coating is also increasingly taken seriously.
The research direction of exterior coating is mainly and studies to have high-weatherability, contaminated resistance good and protect color, prevent at present
Come off the environmentally friendly, exterior coating of hypotoxicity of good performance.Wherein, organosilicon-acrylate paint and esters of acrylic acid coating
Due to the hot topic even more studied at present with good weather resistance and a series of other excellent performances.Acrylic coating is one
Kind of water paint, compared with solvent based coating, water paint has the advantages that lower organic volatile object amount, pollution-free, is one
The coating of kind environmental protection.Water-borne acrylic coatings have the characteristics of adhesive force is strong, are not likely to produce when as exterior coating de-
Fall.Because water-based acrylic resin coating has the advantages of these aspects, therefore acrylic wall paint is studied now
There is good development prospect.
On social development road from now on, traditional exterior wall finish material will be step by step by some environmental protection, green, warp
The high-performance coating of Ji is substituted.From in the market, with from the point of view of future developing trend, acrylic compounds exterior coating will obtain
Very extensive application.In the case where current exterior coating faces existing problems, develop it is a kind of efficiently, cleaning,
The exterior coating of environmental protection is particularly important.
The content of the invention
The technical problems to be solved by the invention are：How to provide that a kind of adhesive force is strong, good endurance, ageing resistance are good
Water paint.
The technical solution adopted in the present invention is：A kind of preparation method of exterior coating, is carried out in accordance with the following steps
Step 1: according to weight fraction, the dispersant of 2-10 parts is added in the deionized water of 60-100 parts and is stirred, so
Added afterwards in stirring at low speed and sequentially add 5-7.5 titanium dioxide and the filler of 60-100 parts, high-speed stirred is to without caking, then
2-6.5 thickener is added, stir the mill base to be formed；
Step 2: according to weight fraction, by the antifreezing agent of 1.2-4.2 parts and the multifunctional assistant of 1.2-6.5 parts under stirring at low speed
Agent is added in 60-100 acrylic emulsions, is stirring evenly and then adding into the mill base of step 1 formation, then adds 2-6 defoaming
Agent, which stirs, obtains exterior coating.
As a kind of preferred embodiment：According to weight fraction, filler is by 10-20 calcined kaolin, the machine swelling of 15-25 parts
Soil, the silica flour of 15-25 parts, the nepheline composition of 20-30 parts, and the weight of silica flour and titanium dioxide ratio is 4:1.
As a kind of preferred embodiment：Defoamer is mineral oil defoaming agent, and dispersant is polycarboxylate sodium's anionic water
Property dispersant, thickener is association thickener, any in water-based thickener, and multifunctional assistant be organic amine auxiliary agent, anti-
Jelly agent is any of ethylene glycol, propane diols.
As a kind of preferred embodiment：Stirred using refiner, wherein：Stirring at low speed speed is 100 r/min~600r/
min；The stir speed (S.S.) of high-speed stirred is the r/min of 3000 r/min~4000.
The beneficial effects of the invention are as follows：The dispersant used in the present invention is the efficient color stuffing dispersant of polycarboxylate sodium,
There is splendid stably dispersing effect to conventional color stuffing such as titanium dioxide, kaolin etc., there is relatively low foam generation rate, it is manufactured
Coating system viscosity stabilization.The multifunctional assistant used in the present invention is the organic amine containing hydroxyl and amido, its be dissolved in water and
Dissolve each other than for 1:100, suitable for water-based emulsion, aqueous latex paint etc., the performance of thickener can be improved, reduces coating ammonia taste, can
Effective control ph, there are relatively wide pH bufferings, in-tank corrosion can be reduced and have fabulous cost performance.Exterior wall of the present invention applies
Adhesive force is strong between material and substrate, and weatherability is good, and ageing resistace is good, there is good workability, service life length.
