Description

A kind of surface treatment method of Dali stone ceramic tile
Technical field
The present invention relates to a kind of surface treatment methods of Dali stone ceramic tile.
Background technology
Chinese real estate in recent years develops on an unprecedented scale, and the building wall, floor ceramic tile market tightened around house property association need Ask huge.As Chinese pottery production technology and technology are grown rapidly, ceramic tile market personalized product protrudes, and product development starts Tend to high-end.Ceramic tile enterprise of China is aiming at high-end market, emphasize to adjust the product mix and is improving the same of added value of product now When, the overall interests of industry are also taken into account, product technology content is improved by effort, increases autonomous innovation.
Indoors in ornament materials for kitchen, bathroom and balcony ground generally using with corrosion-resistant, waterproof, antifouling Ceramic tile since kitchen, bathroom and balcony ground are often in wet and slippery state, commonly uses the big anti-skidding porcelain of skin-friction force Brick.Ship-and-galley tile is a kind of ceramic floor brick, and there are fold striped or sags and crests in front, with increase floor tile face and human body sole or The frictional force of sole prevents from skidding and fall down, and the Antiskid ceramic tile of the prior art is mostly convex equipped with variety of shapes in ceramic tile surface Item is to increase frictional force, however the setting of raised line causes the greasy dirt on ceramic tile to be difficult to clean, and easily grows bacterium.It is in addition, existing Some Antiskid ceramic tiles no longer use cord tissue, but spray fine particle in ceramic tile surface and ceramic tile surface is made to have frosted Effect, but such product can break up the pattern of printed layer in sprayed particle, therefore such product can only change the face of ceramic tile Color and without decorative pattern, product tinctorial pattern is single.
Dali stone ceramic tile refers to there is natural marble texture true to nature, color, penetrating and texture a kind of tile product, Superior function with natural marble decorative effect true to nature and ceramic tile.It is compared to other ceramic tile categories, Dali stone ceramic tile It must assure that again while superior practical performance is chased on the decorative effects such as texture, color, penetrating, texture and feel completely Reach the vivid effect of natural marble, so other ceramic tile categories will be significantly larger than by promoting the difficulty of the practicality energy.
Invention content
In view of the shortcomings of the prior art, the object of the present invention is to provide a kind of surface treatment method of Dali stone ceramic tile, both Anti-skidding, the antifouling comprehensive performance of Dali stone ceramic tile can be improved, and does not influence its surface decoration effect.
To achieve the above object, the technical solution adopted in the present invention is:A kind of surface treatment method of Dali stone ceramic tile, Include the following steps:
(1) by polished and edging, treated that Dali stone ceramic tile is filled waxing processing;
(2) anti-skidding processing is carried out to the marble ceramic tile surface after filling waxing in step (1);
(3) the Dali stone ceramic tile of anti-skidding processing in step (2) is carried out soft throw to wax.
Preferably, filling filler used is Ludox in the step (1).It, will be described big using the Ludox The micropore on the surface of reason stone ceramic tile is filled processing.
Preferably, the technological parameter of waxing processing includes bistrique quantity, abrasive material material and waxing pressure in the step (1) Power, the bistrique quantity 6-10, abrasive material material are rigid abrasive material or middle rigid abrasive material, and the waxing pressure is 12-20MPa. Preferably, the bistrique quantity 7-10, the waxing pressure is 15-19MPa.
Preferably, brick face temperature is 60 DEG C~90 DEG C in the step (1).Preferably, brick face temperature in the step (1) It is 66 DEG C~85 DEG C.
Preferably, anti-skidding processing is that antilubricant is coated on marble ceramic tile surface in the step (2), is dried again later Dry, the antilubricant is the corrosive agent for ceramic tile surface.
Preferably, soft throwing waxing is after anti-fouling agent is uniformly coated on anti-skidding processing using abrasive material in the step (3) Marble ceramic tile surface, formed and the inorganic stain-proofing layer of transparent nano of discontinuous shallow pits be distributed with.
Preferably, the soft throwing waxing condition:Using wax-polishing machine, wax-polishing machine selects 3-6 group bistriques, and abrasive material is soft mill Material, waxing pressure are 7-9MPa.Preferably, wax-polishing machine selects 3-5 group bistriques.
Preferably, the Dali stone ceramic tile is the polished glazed tile that surface is porcelain or the polished glazed tile that surface is enamel.
The present invention provides a kind of Dali stone ceramic tiles obtained using surface treatment method described above.
The surface treatment method of Dali stone ceramic tile disclosed by the invention comes first by adjusting waxing parameter and brick face temperature Then the stability of the raising anti-skidding processing of Dali stone ceramic tile promotes the skid resistance of Dali stone ceramic tile by soft throwing waxing technique and prevents Dirt.Existing waxing production line need to be only slightly improved and adjust corresponding processing parameter, it is possible to significantly improve marble Anti-skidding, the antifouling comprehensive performance of ceramic tile promotes product competitiveness.
Compared with prior art, the beneficial effects of the present invention are:Surface treatment method of the present invention is simple, can continuously make Industry, only need to be slightly improved existing production line can industrialization;This method is seldom to the production cost increases, can but significantly improve Dali Anti-skidding, the antifouling comprehensive performance of stone ceramic tile;The original property indices of ceramic tile are not influenced, such as texture, color and luster, penetrating, texture; It is environmental friendly, environment is not influenced, does not damage the health of worker.
