The sand base brick of the invention has good contamination resistance reaching grade 0 as well as good skid resistance with a friction coefficient higher than 0.7, according to detection; besides, raw materials of the sand base brick of the invention are easily available, and a manufacture method is simple.
Description
Technical field
The sand base brick that the present invention relates to a kind of sand base tile composition and utilize said composition to process.
Background technology
At present, adopt ceramic tile or stone material ground tile paving ground such as grouan, marble mostly.But because the surface compact of ceramic tile or stone materials such as grouan, marble does not have anti-skid.If for the anti-skid that improves them uneven surface is made on its surface, not resistant to pollution problem will be occurred.And ceramic tile need consume a large amount of ore deposit soil resources, and the resource of stone materials such as grouan, marble also is limited.Although the sand base brick of being processed by silica sand and rigid resin sticker not only raw material is easy to get, but also has anti-skid, the contamination resistance of this sand base brick is poor.
Summary of the invention
The objective of the invention is to overcome various brick of the prior art and do not have the good anti-skid and the problem of contamination resistance simultaneously; A kind of sand base tile composition that can process the sand base brick that anti-skid is good, contamination resistance is excellent is provided, and the sand base brick of processing by said composition.
Contriver of the present invention discovers; After the reason of the sand base brick contamination resistance difference of being processed by silica sand and rigid resin sticker possibly be the rigid resin adhesive cures; Making has the burr that forms after the adhesive cures in the micropore of brick surface; This burr forms the pore that is prone to the absorption dirt, thereby causes contamination resistance poor.When contriver of the present invention also finds to use silica sand and flexible resin to make sand base brick; The sand base brick that obtains cleans easily; Brick surface micropore is stopped up, and, because of the surface irregularity of sand base brick; Make this sand base brick have good anti-skid, do not have the good anti-skid and the problem of contamination resistance simultaneously thereby solved various brick of the prior art.
The present invention provides a kind of sand base tile composition; This sand base tile composition contains the aggregate and first sticker; The aggregate and first sticker exist with independent component respectively; Perhaps the aggregate and first sticker exist with form of mixtures, and said aggregate is silica sand and/or the silica sand with polymer covering layer, and said first sticker contains flexible resin.
The present invention also provides a kind of sand base brick, and this sand base brick is that above-mentioned sand base tile composition is processed sand base brick prefab, and first adhesive cures that will be wherein obtains.
Sand base brick of the present invention has good contamination resistance, can reach 0 grade through detecting the contamination resistance grade.And this sand base brick also has good anti-skid, through detecting frictional coefficient all more than 0.7.This possibly be because the curing speed of flexible resin is slower, does not form burr and pore after making the brick surface micropore of sand base brick solidify, and micropore surface is smooth; Therefore there is not the problem of adsorbing dirt, thereby cleans easily, brick surface micropore is stopped up; And; Because of the surface irregularity of sand base brick, make this sand base brick have good anti-skid, do not have the good anti-skid and the problem of contamination resistance simultaneously thereby solved various brick of the prior art.In addition, the raw material of sand base brick of the present invention is easy to get, and method of manufacture is simple.
