Background technology
Along with the development of modern architecture industry, particularly along with the remarkable improvement of people's quality of life, to the requirement also corresponding raising of construction material, with regard to the roofing tile as building roofing material, not only desired strength is high, lightweight, ideal flatness, weatherability (antifreeze, waterproof) are good and flameproof effect excellent, and sight property is also comparatively paid close attention to, so-called sight is as good looking appearance and rich color etc.
Known roofing tile mainly contains clay shingle, cement tile and glazed tiles etc., and the production technology of this roofing tile is mostly by wet method (i.e. wetpressing) preparation.With regard to clay shingle, its preparation technology is followed successively by; To the artificial pugging of clay, make by hand, natural drying and earth kiln burn till, the shortcoming of existence is: system watt labour intensity is large, efficiency and yield poorly, intensity difference and easily broken, sight property difference and weatherability shortcoming (easily infiltration, weathering); With regard to cement tile, raw material is cement and yellow ground and according to adding auxiliary agent, preparation technology is by mould molding, and the shortcoming of existence is: heavy, production efficiency is low, it is poor easily to gather trifle in the world and easy-weathering and sight property; With regard to glazed tiles, because it belongs to Handicraft decorative watt category, thus not only material combination is complicated, and manufacture craft is cumbersome, need about 72h consuming time from biscuit to finished product, can by the production technology of CN1042894A(glazed tiles and compounding method thereof to this) and the preparation method of a CN1143058A(new type glass tile) confirm.
The technical information about roofing tile and preparation method thereof can be seen in disclosed Chinese patent literature: as: application for a patent for invention publication number CN1657474A recommends to be had " sintering free construction tile and manufacturing process thereof ", this raw material (by weight) selected by patent application scheme is: cement 100 parts, flyash 30-35 part, slag 150-200 part, and this watt is essentially aforesaid cement tile category; And for example: CN1388083A provides " environment-protecting color baking-free tile and manufacture method thereof ", raw material (by weight) is: cement 25 parts, sand 25 parts, 2.5 parts, calcium carbonate, 2.5 parts, barium sulfate, brightener 0.7 part, quick dry agent 0.5 part, pigment 12.5 parts, promoter 0.5 part, antifreezing agent 0.3 part, releasing agent 0.5 part and 30 parts, water, and this patent application scheme belongs to cement tile category equally; For another example: CN1097183A discloses " a kind of building ceramic watt and production technology ", raw material (by quality %) is: gold ore tailing 70-80%, clay 12-25% and flint clay powder 0-8%, cause trouble to storage and transport due to heaviness for this watt, in addition due to needs twice firing, thus large, the complex process of energy consumption and yielding poorly in preparation process; Also have " a kind of manufacture method of colour glaze-imitating brick " as: CN100404470C introduces, the concrete raw material that this patent formula introduction is selected and proportioning thereof, emphasis teach by be 0.2-0.5MPa by means of spray gun with pressure by acrylic ester type encaustic tile coating, spray gun atomization angle 30-50 ° and spray gun spray on potter's clay unbaked tile from the state of potter's clay unbaked tile 15-50 ㎝.
