Description
Technical field
The invention belongs to interior wall coating field, and in particular to a kind of preparation method of multifunctional inner wall coating material.
Background technology
Architectural Paint in China accounts for the 40% of whole coatings industry, and interior wall coating typically constitutes from 70% left side of architectural decoration coating material
The right side, is one of primary pollution source of indoor VOC (VOC).With the serious and indoor disease of environmental pollution
Increase, requirement more and more higher of the mankind to living environment is all thirsted for possessing suitable life, a working environment.According to statistics, people
Time for having 70% or so in all one's life spend indoors.Therefore, quality breath manner of breathing of the health of people with IAQ
Close.People become more concerned with the capability and performance of interior wall coating and its influence to health.The decoration of interior wall coating is imitated first
Really (color, texture and flatness etc.) is paid close attention to by people；Secondly interior wall coating can produce larger shadow to indoor environment
Ring, it should have appropriate gas permeability and hygroscopicity, and complete airtight, nonhygroscopic film can cause metope to condense, unfavorable
In the improvement and the raising of comfortable for living of indoor environment；Finally increasingly by it is of concern be that can not contain in interior wall coating
There are poisonous and harmful substances, to reduce the damage caused to human body as far as possible.After use, metope is easily infected with spot to interior wall coating,
The scrubbing resistance ability of presently commercially available common interior wall coating is poor, therefore is badly in need of a kind of excellent interior wall coating of wash-resistant property.
The content of the invention
It is excellent and the preferable interior wall coating of moisture absorption and desorption property it is an object of the invention to provide a kind of wash-resistant property
Preparation method.
The present invention is achieved by the following technical solutions.
A kind of preparation method of multifunctional inner wall coating material, including following operating procedure：
（1）After starch volume fraction is handled for 30% hydrogen peroxide oxidation, oxidized starch is made standby；
（2）Sepiolite powder is broken to after 500-600 mesh, the POLYPROPYLENE GLYCOL that 0.1-0.3 times of its weight is weighed is added thereto, is then pressed
According to solid-to-liquid ratio 1kg:3-5L adds water thereto, slowly boils water, and keeps after fluidized state 5-10min, takes out filtering, obtains
To modified meerschaum；
（3）40-50L water is added into every kilogram of auxiliary agent, after being mixed evenly, pure-acrylic emulsion is added thereto, then to its
Middle addition oxidized starch, modified meerschaum, after being mixed evenly, are made the body of multifunctional inner wall coating material, wherein pure-acrylic emulsion
Product is 2-3 times of water volume.
Specifically, above-mentioned steps（1）The mass volume ratio of middle starch and hydrogen peroxide is 1kg:0.8-1.2L, specifically aoxidizes work
Skill is：Starch is added into hydrogen peroxide, the temperature of mixture is risen to 70 DEG C, after being incubated 1 hour, oxidized starch is made.
Specifically, above-mentioned auxiliary agent is made up of the component of following parts by weight：10 parts of polyethylene glycol 200, thickener TT-935
13 parts, 8 parts of defoamer BYK-024.
Specifically, above-mentioned oxidized starch, modified meerschaum, the mass ratio of pure-acrylic emulsion are 1:17-23:18-20.
Technical scheme more than, the beneficial effects of the invention are as follows：
The preparation method for the multifunctional inner wall coating material that the present invention is provided, safety and environmental protection is nontoxic, meets the items of interior wall coating
Basic demand, interior wall coating especially produced by the present invention, wash-resistant property is excellent, is infected with the spot on its surface, erasable
Go, and moisture absorption and desorption property is excellent, and when indoor water capacity is higher, coating can absorb water vapor in air；When interior is relatively wet
When spending relatively low, the vapor of coating storage is then released, so that human body is lived under suitable humidity.Wherein, the present invention exists
Oxidized starch is added in interior wall coating, every mechanical property of coating can be effectively lifted, and make it that coating surface is more smooth,
The almost presence of bubble-free, greatly improves the wash-resistant property of coating；In the present invention, by the way that sepiolite is modified,
So that sepiolite surface attachment has substantial amounts of hydroxyl functional group so that change of the sepiolite to moisture content in air is quicker
Sense, greatly improves interior wall coating to moisture absorption and desorption property.
