Formaldehydeless without benzene class thing coating and preparation method thereof
Technical field
The present invention relates to a kind of coating, especially relate to a kind of environment-friendly formaldehyde-free without benzene class thing coating and preparation method thereof.
Background technology
Along with the cognitive level of modern and growth in the living standard, more and more higher to the house ornamentation environmental requirement, existing decoration coating type is a lot, and be meeting the market requirement, coating material production producer is also improving constantly the research of environmental protection coating material, but existing environmental protection coating material can bring a lot of problems, makes its conformance with standard such as just the index of volatile matter having been reduced.Really zero VOC of the development trend of present coating industry, tasteless health paint.But be subject to the factors such as technology, almost do not have on the market the environmental protection coating material of real zero VOC, it contains some objectionable impurities, has seriously injured the healthy of people, has destroyed people's living environment.
Summary of the invention
The problem to be solved in the present invention provides a kind of environment-friendly formaldehyde-free without benzene class thing coating.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of formaldehydeless without benzene class thing coating, it is characterized in that: be that raw material by following weight percent is prepared from:
Described auxiliary agent comprises propylene glycol, defoamer and flow agent, and weight proportion is between each component: propylene glycol: defoamer: flow agent=5-7: 1-2: 0.5-1.
Described tangerine orange elite preparation method may further comprise the steps:
(1) the tangerine orange peel is clean with the clear water rinsing, by weight, get 1 part of the tangerine orange peel that cleans up, 4 parts of hardening liquids mix, and the tangerine orange peel all is immersed in the hardening liquid, soak 12-15 hour, make the sclerosis of tangerine orange peel;
(2) immersion is pulled the tangerine orange peel out after finishing from hardening liquid, with the roller squeezer squeezing, obtains the mixed solution of tangerine orange peel slag, tangerine orange oil and water;
(3) filter, except the orange peel removing slag, obtain the mixed solution of tangerine orange oil and water, the mixed solution of tangerine orange oil and water filters through 80~120 mesh filter screens, and the filtrate that obtains is centrifugal under the 15000-18000r/min rotating speed, and extracting centrifugal liquid obtains the tangerine orange oil;
(4) the tangerine orange oil of gained more than 5 days, is got filtrate 3 ℃-7 ℃ storages after the filtration, is tangerine orange elite.
Further, the hardening liquid in the described step (1) is comprised of the component of following weight proportion:
Water 99%-99.5%
Sodium Benzoate 0.05%-0.25%
Calcium Chloride Powder Anhydrous 0.25%-1.25%
Sodium bisulfite 0.03%-0.08%.
Described defoamer is the NXZ defoamer.
Described flow agent is the LK600 flow agent.
Another object of the present invention is to provide a kind of formaldehydeless preparation method without benzene class thing coating.
For solving the problems of the technologies described above, the technical solution used in the present invention may further comprise the steps:
(1) defoamer of the deionized water of formula ratio, titanium dioxide, Paris white, talcum powder, 2/3 propylene glycol and 2/3 is added in the dispersion tank stirs, obtain slip;
(2) slip is ground to the fineness of 30 μ m, and under the speed of 200r/min, stirs;
(3) part propylene glycol, defoamer and the flow agent of adding tangerine orange elite, wheat straw paper pulp, remainder mix to evenly, just obtain environment-friendly type aqueous coating.
Advantage and positively effect that the present invention has are: owing to adopting technique scheme, do not contain the objectionable impuritiess such as formaldehyde, benzene class thing, heavy metal, the quality of filming is ultra-fine greasy, plentiful, strong covering power, antibiotic, the fungicidal properties of natural excellence, but airtight execution do not contain poisonous unwanted volatile matter.
Embodiment
Embodiment 1:
A kind of formaldehydeless without benzene class thing coating, be prepared from by the raw material of following mass percent: tangerine orange elite 0.1%, wheat straw paper pulp 0.5%, titanium dioxide 18%, Paris white 24%, talcum powder 22%, deionized water 28%, propylene glycol 5.9%, defoamer 1%, flow agent 0.5%.
Wherein wheat straw paper pulp is by on the market public sale acquisition, for example Shanghai Kai Chang International Trading Company Ltd; Defoamer is the NXZ defoamer, by on the market public sale acquisition, for example Beijing Nuo Puke commerce and trade company limited; Flow agent is the LK600 flow agent, is obtained by public sale on the market, and for example imperial chemical science and technology Development Co., Ltd is risen in Tianjin.
Wherein, tangerine orange elite is that the tangerine orange peel is clean with the clear water rinsing, by weight, gets 1 part of the tangerine orange peel that cleans up, and 4 parts of hardening liquids mix.
Described hardening liquid is comprised of the component of following weight proportion: water 99.2%, Sodium Benzoate 0.2%, Calcium Chloride Powder Anhydrous 0.55%, sodium bisulfite 0.05%.
The tangerine orange peel all is immersed in the hardening liquid, soaked 13 hours, make the sclerosis of tangerine orange peel; After soaking end the tangerine orange peel is pulled out from hardening liquid, with the roller squeezer squeezing, obtained the mixed solution of tangerine orange peel slag, tangerine orange oil and water; Filter, except the orange peel removing slag, obtain the mixed solution of tangerine orange oil and water, the mixed solution of tangerine orange oil and water filters through 120 mesh filter screens, and the filtrate that obtains is centrifugal under the 16000r/min rotating speed, and extracting centrifugal liquid obtains the tangerine orange oil; The tangerine orange oil of gained is got filtrate 6 ℃ of storages 7 days after the filtration, be tangerine orange elite.
The preparation method of this environmental protection coating material may further comprise the steps:
1, NXZ defoamer, 180g titanium dioxide, 240g Paris white, the 220g talcum powder of the propylene glycol of deionized water 280g, 39g, 7g added in the dispersion tank stirs, obtain slip;
2, the slip after will disperseing is ground to the fineness of 30 μ m, and stirs under the speed of 200r/min;
3, add again part propylene glycol 20g, NXZ defoamer 3g, the LK600 flow agent 5g of tangerine orange elite 1g, wheat straw paper pulp 5g, remainder, mix to evenly, just obtain environment-friendly type aqueous coating.
Embodiment 2
