Description

A kind of conch meal wall covering and its production and use
Technical field
The present invention relates to a kind of coating and its production and use, relate more specifically to a kind of conch meal wall covering and its production and use, belong to technical field of coatings.
Background technology
Coating, be a kind of body surface that can be coated in order to protect or the functional chemical industry preparation of decorating objects, it usually forms the thin film of secure adhesion with coated article, and shows diversified defencive function.
Wall covering is known by paint field, existing wall covering function singleness, is particularly easily subject to oil pollution.Existing wall covering, the coating owing to being formed does not have enough mechanical strengths and wearability, after being subject to long-time impact and mechanism, can quickly wear and tear, or even peel off and lose the protective effect to base material.Along with the prolongation of the time of use, the loss of organic silicone oil, viscosity will not be gradually lowered, and therefore cannot there is not viscously the problem that persistency is not enough.Therefore, it remains desirable to metope can improve further in application and performance, especially in thin film-forming method, film-forming temperature, hardness, wearability, not viscous persistency.
Conch meal is that it can be applicable in various chemical products such as coating, has certain absorption and sterilizing function by the shell of various shells passes through the powder processed.Therefore, for the comprehensive utilization of conch meal, not only can consuming substantial amounts of shell on the one hand, thus protecting environment, can turn waste into wealth on the other hand, it is achieved its deep processing and utilization.Therefore, for using the research of the various chemical productss of conch meal, become the focus and emphasis problem of a research at present, and achieve many achievements.Such as, up to the present, it have been reported that several functions coating especially comprises the coating of conch meal in prior art.But, the conch meal of nano modification is used for not gluing wall covering but without open report by prior art.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, in order to prepare conch meal wall covering, this is conducted in-depth research by the present inventor, having paid substantial amounts of creative work and after further investigation is explored, thus completing the present invention.In order to realize the purpose of the present invention, intend adopting the following technical scheme that
One aspect of the present invention relates to a kind of conch meal wall covering, it is characterised in that described conch meal wall covering contains the nano-material modified conch meal of 50-60% percentage by weight.
In a preferred embodiment of the present invention, described nano-material modified conch meal is made up of the nano aluminium oxide of 5-10% percentage by weight, the nano silicon of 5-10% and the conch meal of surplus.
In another preferred embodiment of the present invention, described nano-material modified conch meal is prepared by method and prepares:
(1) being calcined 60-80 minute at 750-850 DEG C by clean oyster shell, be then naturally cooling to room temperature, after calcining, shell is pulverized, is ground, and crosses 200-300 mesh sieve, obtains conch meal, be separately added into nano aluminium oxide and nano silicon oxide, mix homogeneously;
(2) gradient calcining and quenching it are sequentially carried out, concrete operations are: carry out calcining 10-15 minute at 380-420 DEG C, then it is warmed up to 480-520 DEG C with the heating rate of 8-12 DEG C/min, and insulation is calcined 20-25 minute at such a temperature, it is placed in the ethanol water of 15-25% volumetric concentration while hot and lowers the temperature quenches;Filtering after quenching, filtering residue is warmed up to 680-720 DEG C with the heating rate of 3-7 DEG C/min, and insulation is calcined 30-40 minute at such a temperature;Calcining naturally cools to room temperature after terminating, and is again pulverized by conch meal, grinds, crosses 200-300 mesh sieve, obtain nano-material modified conch meal.
In a preferred embodiment of the present invention, described conch meal wall covering is possibly together with the fluoric silane of the alkoxide of 8-12% percentage by weight, the pigment of 5-10% percentage by weight, the water of 20-30% percentage by weight and 3-5% percentage by weight;Preferably, described conch meal wall covering does not contain other component.
In a preferred embodiment of the present invention, described alkoxide is selected from metal alkoxide or nonmetal alkoxide;As preferably, described alkoxide is selected from one or more in tetrabutyl titanate, silester, aluminum isopropylate..
In a preferred embodiment of the present invention, described pigment is black selected from titanium dioxide, carbon black, graphite, high titanium ash, titanium yellow, cobalt titanate green, ferrimanganic, in cobalt blue, copper-chrome black one or several:
In a preferred embodiment of the present invention, described fluoric silane is selected from one or both in ten difluoro heptyl propyl trimethoxy silicanes, 13 fluoro octyl triethoxysilanes.
In a preferred embodiment of the present invention, the hardness of described conch meal wall covering is more than or equal to 9H.
In a preferred embodiment of the present invention, the wearability number of times of described conch meal wall covering is more than 8600 times.
The preparation method that another aspect of the present invention further relates to above-mentioned conch meal wall covering, it is characterised in that comprise the steps: that titanium dioxide and all nano-material modified conch meal and 13 fluoro octyl triethoxysilanes by 50% disperse dispersion 1 in dispersion machine;It is heated to 35-45 DEG C in the titanium dioxide of other 50%, whole tetrabutyl titanate and deionized water and stirring situation, Heat preservation 10-20 minute, resulting dispersion 2, dispersion 1 and 2 is mixed, stirring, 400 orders obtain wall covering after filtering.
The invention still further relates to the using method of above-mentioned coating, by wall covering spraying on the metope adopting putty to process, toast under infrared lamp.
Modified by various ingredients and material of coating of the present invention, and specific components selection collocation and specific preparation method, formula is simple, synergistic function is played between each component, and then make that obtained coating has good not viscous persistency, hardness is high, anti-wear performance is good, there is good application potential and industrial production value widely.
Detailed description of the invention
If not specified, that technological means used in embodiment is well known to those skilled in the art conventional means.
Embodiment 1:
Method of testing in detection method:
1* (heat resistance): cated film will be sprayed after 180 DEG C of baking 2h, put in the Ovenized electric furnace of potential difference meter verification, temperature is raised by 5 DEG C/min, starting timing with furnace temperature to requirement of experiment temperature, sample, after continuous high temperature, takes out, it is cooled to room temperature (25 DEG C), coating surface situation is observed, as without be full of cracks, obscission, namely illustrated that coating heat resistance can be good with magnifier.
2* (not viscosity test): spraying cated film, heating, to 90 DEG C, directly places a raw egg peeled off on its surface;Being always maintained at heating, until the complete fry cooked of egg, promote egg gently with wooden scoop, as egg peels off naturally, non-sticky property is excellent;Slightly adhering to (adhered area is less than 30%), non-sticky property is general;Adhering to serious (adhered area is more than 60%), even can not peel off, non-sticky property is for poor.
3* (resistance to high wet performance): just spray cated film after 180 DEG C of baking 2h, be cooled to room temperature, then test piece be positioned in the distilled water of 100 DEG C, heat and destroy to paint film, occur such as phenomenons such as foaming, loss of gloss, variable color, be full of cracks.
