Description
Technical field
The present invention relates to a kind of manufacture method of gypsum base function sheet material, belong to building material technical field.
Background technology
The gypsum sheet material of all size now commercially sold, covers paper by terra alba through the stirring that adds water or does not cover paper aftershaping and dry and form, be widely used as the dalles such as the partition in house decoration, furred ceiling.Because it is lightweight, easy construction, subsequent decorations its market simple application is more and more extensive, and annual requirement has reached more than 4,000,000,000 square meters; But plasterboard in use also exists number of drawbacks: one, waterproof and dampproof poor performance, causes it can not be used for kitchen guarding and decoration of exterior wall; Its two, low strength, causes being used for antitheft interval and load larrying member; They are three years old, toxic and harmful can not be removed, nowadays house is for adaptation slow setting, diminishing, pumping just use a large amount of additives in manufacture process, and when fitting up, some artificial stone-like materials, glued board, coating etc. are also containing some objectionable impuritiess, typical in common curatives formaldehyde etc.Along with the growth in the living standard of people, higher level is risen to the improvement of living conditions, people are synchronous with the various science and technology of society in the urgent need to the technology content of the material in room, typical in antibacterial, easy clean, formaldehyde adsorption, anion releasing, far infrared rays, thus the object reaching disease curing health, promote longevity.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of gypsum base function sheet material, there is antibacterial, easy clean, formaldehyde adsorption, anion releasing far infrared rays plaster-based board in order to produce more, meet the needs of people to environment-friendly building materials.
For realizing its object, the present inventor is in view of above-mentioned practical situation, the experience of inorganic functional material research is engaged in conjunction with two more than ten years, particularly in the control to functional, security, economy, weather resistance in industrialization process of various new technology, novel process, in gypsum base material, reach antibacterial, easy clean by modification first, the object of formaldehyde adsorption, anion releasing far infrared rays, thus complete technical scheme of the present invention.First this technical scheme makes functional material, again functional material and gypsum powder are carried out compound, its feature is: the manufacture method of described functional material: cross 1200 mesh sieves after comprising batching, grinding, sintering, again superfine pulverizing, wherein said batching is: assort following starting material by weight percentage: technical pure zirconium white 40% ~ 60%, titanium dioxide (anatase titanium dioxide) 10% ~ 20%, oxidation Cerium 20% ~ 30%, zinc oxide 10% ~ 20%; Described grinding, sintering, again superfine pulverizing are: by above-mentioned materials mixing, grinding, cross 400 mesh sieves, grog is sintered into subsequently in shuttle kiln, its temperature controls at 1150 DEG C ~ 1250 DEG C, firing time is within 8 hours, clinker cooling fully after grinding, cross 1200 mesh sieves, the functional material of antibacterial, easy clean, formaldehyde adsorption, anion releasing far infrared rays powder shape.
2, described functional materials and gypsum powder being carried out compound, is mixed with gypsum powder 90-99% by the functional material 1-10% made by weight percentage, then through stirring, homogenizing, old, shaping gypsum base functional panels.
3, described functional materials and gypsum powder are carried out compound, the PVA-1799 of functional materials powder 95-98% and 2% ~ 5% will made by weight percentage, after being fully uniformly mixed, make functional film through thermosol, then functional film and gypsum sheet material are combined with each other gypsum base function sheet material.
4, described functional materials and gypsum powder being carried out compound, is that the functional materials made is made colloid, then spray or be printed on gypsum board surface gypsum base function sheet material.
Compared with prior art, the present invention has following features and progress: owing to present invention employs by technical pure zirconium white 40% ~ 60%, titanium dioxide (anatase titanium dioxide) 10% ~ 20%, oxidation Cerium 20% ~ 30%, the functional material that zinc oxide 10% ~ 20 material is made, the method for tradition gypsum sheet material processed can be adopted to be participated in terra alba by described functional material and to produce have that antibacterial, easy clean, formaldehyde adsorption, anion releasing far infrared rays gypsum base is antibacterial, easily cleaning function sheet material; Also the functional material made first can be made film, then this is by the surface of film applying at existing plasterboard, becomes to have that antibacterial, easy clean, formaldehyde adsorption, anion releasing far infrared rays gypsum base is antibacterial, easily cleaning function sheet material; The functional material made first can also be made colloid, then this colloid is brushed to the surface of existing gypsum sheet material, become and have that antibacterial, easy clean, formaldehyde adsorption, anion releasing far infrared rays gypsum base is antibacterial, easily cleaning function sheet material.Therefore the method is simple, easy to use, it is low and can the advantage of antibacterial, easy clean, formaldehyde adsorption and anion releasing far infrared rays that the sheet material made has cost, can improve the living conditions of people, improve the standard of living of people, be conducive to the healthy of people and promote longevity.
Precaution: 1, the manufacture of gypsum powder, adopt the technology of universal mature, but need detect the heavy metal Hg of chemical gypsum (phosphogypsum, desulfurated plaster etc.), arsenic, cadmium, chromium, plumbous content, radiation element and fluorine when selecting gypsum raw materials and fuel, within making above-mentioned substance be strict controlled in national standard content, must not exceed standard.After functional powder or functional powder film and gypsum are combined with each other, also to detect, qualifiedly after testing just can become qualified product afterwards;
2, present method adds a burden agitator before traditional gypsum board line manufacturing process tank, usually gypsum powder 90% ~ 99%, function powder 1% ~ 10%, through batching, stirring, old, homogenizing, enter panel production line servo tank, produce by original production process and can produce gypsum base functional panels;
3, it should be pointed out that, when functional powder reaches 10%, its cost and effect also reach maximization, when functional powder reaches 1%, also substantially can meet the use of impermanent engineering, thus reach good cost performance;
4, another kind of method with plastic film and overlay film plasterboard streamline mixed production popular now, its difference is that one is utilize homemade functional membrane, and one is spraying function powder on the film or plate membrane junction face of common overlay film line.
Embodiment
Below in conjunction with embodiment, the present invention is further described:
