Description
Technical field
The present invention relates to a kind of floor tile, especially relate to a kind of through flyash RPP/poly macromolecule one inorganic composite materials floor tile and preparation method thereof.
Background technology
At present; Most of outdoor ground tile all adopts the concrete floor tile; Though its application is wide, easy to use, have that quality is heavy, impact resistance is not good, be prone to weak points such as warpage or breakage when bearing big pressure, and its discarded back recycling property is poor; Its maximum problem is the regeneration of can't degrading, thereby causes the waste of environment damage and resource.
Because the polymer composite floor tile has following characteristics:
1. light weight transports and mats formation conveniently;
2. long service life is prone to the cleaning maintenance, can bear load-carrying vehicle and moderate finite deformation;
3. anti-skidding safety, the polymer composite floor tile can freely design on brick face decorative pattern, material proportioning, and the surface has certain roughness, and friction factor can reach anti-skidding standard, and feel is comfortable;
4. can recycle again after the polymer composite paving brick breakage, help environmental protection and sustainable development of resource;
5. the polymer composite floor tile adopts personalized design, and moulding can be divided into common shaped brick and special form brick, and shape is various, the various patterns of one-tenth capable of being combined, and receive people's attention day by day, become a kind of widely used novel pavement material gradually.
In recent years, though plastic floor tile has obtained significant progress, the only suitable indoor decoration usefulness of major part, and mechanical property is not enough, intensity is not high, price is expensive partially etc., can't be applied to outdoor.This is that friction factor is unstable because simple polymer matrix composites resistance to elevated temperatures is poor, and the heat fading phenomenon is serious, wears no resistance, and has limited its range of application to a certain extent.Through in polymer matrix composites, adding different fillers, can obviously improve its tribological property and engineering properties, can make it be applied to the outdoor ground tile field.Industrial residue flyash has the potential quality as friction material constituents, is a kind of reasonable powder of filling out, and the coal ash main chemical compositions is SiO

3Deng, have good stability, inexpensive, sound insulation, advantage such as wear-resisting.Flyash has similar character with the filler kieselguhr of macromolecular material with bauxite, can be used as the filler of macromolecular material.
The advantage of flyash filled polyolefin composite material is:
1) main component of flyash is silica (SiO
2) glass microsphere that forms, add and be prone to man-hour be distributed in the resin and be evenly distributed, can avoid irregularly shaped or stress that wedge angle caused is concentrated.The processing fluidity that also makes it that " ball effect " takes place in the machining stress field simultaneously and show filled high polymer composite material is far above calcium carbonate, French chalk filled high polymer composite material;
2) contain about 24% the glass microballoon of having an appointment in the flyash, it is low that polyolefin strengthens the back oil absorbency through flyash, and viscosity decline helps the coating of resin to other fillers, auxiliary agent;
3) flyash can reduce the coefficient of thermal expansion reduction and the shrinkage factor of composite polyolefine material, can improve the dimensional stability of goods, and can effectively improve the crocking resistance of goods.
4) flyash is the discarded object of power plant, and cost is lower, and the reinforcing agent use as macromolecular material can reduce environment pollution, has also realized the recycling of flyash, meets the development model of recycling economy.
In view of the having a extensive future of composite polymer-inorganic matter material floor tile, many researchers are to utilizing vistanex and prepare the polymer composite floor tile and flyash being studied as reinforcing material.
Liu Tong (Liu Tong; The research of modified coal ash filled polyethylene [J]. Guizhou University of Technology's journal (natural science edition); 2008,37 (2)) mechanical property of composite material behind the modified coal ash filled polyethylene has been discussed, has been introduced the influence of different coupling agents and the optimum addition of flyash.
Horse advance (horse advances, the research and development of superfined flyash filled polypropylene [J]. Chinese polymer composite, 2001,15 (7)) inquired into flyash to MODIFICATION OF POLYPROPYLENE.
Wang Zhanhong and Hou Guihua (Wang Zhanhong and Hou Guihua; Flyash strengthens polymer matrix composites mechanical property and Study on Tribological Properties [J]. lubricated and sealing; 2009; 34 (4)) inquired into the polymer matrix composites that adopt hot press molding method to prepare fly ash, and mechanical property, section microstructure and the tribological property of this composite material have been studied.
Gu Dechao (Chinese patent, CN1546558A, polymer environment protection type ship-and-galley tile technology and prescription) provides a kind of method of utilizing industrial manufacture of polyolefins polymer composite floor tile.Above-mentioned research report does not relate to utilizes flyash RPP/composite polyethylene material to prepare polymer composite material interlocking type ground tile.
