Step 4：The mian paint of step 2 is mixed with the curing agent of step 3 by 5: 1 weight than stirring, target product is obtained.
The present invention principle be：Oyster shell whiting will be propagated artificially with natural shell by being made after high-temperature calcination, crushing.
Its constituent is the calcified material such as calcium carbonate, calcium oxide, calcium hydroxide, this as cellular, with absorption, decompose (formaldehyde,
Benzene, TVOC, ammonia) effect and adjusting air humidity, odor eliminating function.The compound of calcium is used for taste removal in life
Agent, therefore the smell that can be distributed to indoor smoke, infant, patient, pet, mould of oyster shell whiting and indoor miscellaneous taste all have
There is the effective effect of dispelling, the carbon monoxide and dust Capacity especially distributed indoors to cigarette has suction-operated.Shell
Its composition 100% of powder is calcium, therefore with good antistatic performance.The oyster shell whiting fired simultaneously is to including Escherichia coli, sand
Various bacteria including door Salmonella, yellow glucose fungus etc. has extremely strong antibacterial and a bactericidal action, and with anti-corrosion, mould proof
Function；By litsea citrate oil, caryophyllus oil, cinnamon oil, propionic acid, sorbic acid, fumaric acid, natamycin, allicin, sodium Diacetate, sweet
The mould inhibitor that is mixed to get by both certainty ratios of dew glycan, each component and oyster shell whiting Synergistic so that final floor paint it is mould proof,
Antibacterial effect strengthens, and then ensures that the bottom surface that the later-stage utilization gravity flow self-leveling floor paint is spread is not gone mouldy and breed bacteria, seeks
Make one it is with fresh air and prevent ground mildew or bacteria breed contribute to the indoor environment of live and work.
It was found from foregoing description, the beneficial effects of the present invention are：(1) mian paint in gravity flow self-leveling floor paint of the invention and
Curing agent is free of hazardous solvent, more environmentally-friendly；(2) gravity flow self-leveling floor paint of the invention uses oyster shell whiting for main stuffing, shellfish
Shell powder gas permeability and good water permeability, with the function of adsorbing and discharge air humidity, with good moisture effect, there is texture；
The function (more environmentally-friendly) of reduction formaldehyde in air and pernicious gas content can be adsorbed simultaneously, it is anti-with carbon dioxide in air
The effect for also showing Synergistic between the hard coat of calcium compound, each component unexpectedly should be generated, makes its comprehensive
It can improve；Meanwhile, there is certain anti-corrosion function containing chitin in oyster shell whiting；(3) the original painting of gravity flow self-leveling floor paint is not being changed
Adorn under conditions of technique, using the mildew-proof function of oyster shell whiting, then by increasing mould proof composition, each component Synergistic in mian paint
To further ensure that the ground spread using the gravity flow self-leveling floor paint is not gone mouldy in the future, not breed bacteria；(4) it is of the invention
Preparation method, mould proof component is encapsulated in porous-starch shell, has both effectively prevented product processing from, because dealing with improperly, causing
The volatilization of mould proof material, the problem of mould proof, antibacterial efficacy is reduced, reduce again because mould proof component is unstable and with other compositions phase interaction
With the problem of, the evaporation rate that can slow down mould proof material effectively extends antimildew and antibacterial using ground obtained by the gravity flow self-leveling floor paint
Time；(5) preparation method of the invention, step is simple, and condition is easily-controllable, and replicability is strong.
Further, the oyster shell whiting is modified Nano oyster shell whiting, and the modified Nano oyster shell whiting is made by following steps：
Step a：Shell is cleaned with clear water, dried, the 0.5~1mm thick micro mist of shell is then crushed to；
Step b：The thick micro mist of step a shell is placed in progress calcining expanding treatment in high temperature resistance furnace, using four-part form
Gradient is calcined, and concrete operations are：It is initially positioned at 300 DEG C and carries out 20~40min of calcining；Again with 5~10 DEG C/min heating rate
600 DEG C are warming up to, 30~45min of calcining is carried out in 600 DEG C；Then 900 DEG C are warming up to 5~10 DEG C/min heating rate,
30~60min of calcining is carried out in 900 DEG C；1200 DEG C finally are warming up to 5~10 DEG C/min heating rate, in 1200 DEG C of progress
45~60min is calcined, calcining naturally cools to less than 28 DEG C after terminating, must calcine expanded thick micro mist；
Step c：The expanded rear thick micro mist of step b calcining is subjected to nanometer pulverization processing using nano grinder, changed
Property nanometer oyster shell whiting.
Seen from the above description, high by the above-mentioned shell powder fineness manufactured meticulously, whiteness is good, there is good covering power,
Quality is light, and brushing surface is big, and porous fibrous, adhesion is strong.
Further, the shell is the one or more in mussel shell, scallop shell, oyster shell, cycle of sixty years shell and Corbicula fluminea shell.
Seen from the above description, above-mentioned shell source is wider, and amount is more, can effectively reduce oyster shell whiting cost.
