Abstract
The invention discloses a permeable water-retaining agent for floor tiles. The permeable water-retaining agent for the floor tiles is prepared by the following components according to the following mass ratio: 60-70 porous materials, 10-20 water-retaining component, 5-10 silicate concrete and 1-3 adhesive. The obtained permeable water-retaining agent for the floor tiles has the effects of filling and water-retaining, can not be hardened and has better water permeability and water-retaining property for a long time. The material can prevent foreign objects from blocking pores by being injected or doped in the floor tiles as a pore filler in advance, thereby maintaining the good properties of permeable concrete for a long time. In addition, as the filler forms a flexible structure in the pores, the permeable water-retaining agent can absorb the expansion pressure during the freezing of water, thereby being conductive to improving the frost resistance of the concrete.
Description
One, technical field
Invention relates to a kind of floor tile permeable water-retaining agent, belongs to civil engineering material technical field.
Two, background technology
In recent years, quickening along with Urbanization in China, the fraction of coverage of mating formation of urban ground improves year by year, data shows, even not considering the ground of square, residential quarters etc. mats formation, China only fraction of coverage of urban road has reached 10%～18%, and the megalopolis has surpassed 20% even 25%, and fraction of coverage also will further improve from now on.Owing to adopt at present usually bituminous concrete and cement concrete to carry out density mat formation (non-permeable pavement), blocked the water-retentivity of upwards evaporating and having reduced ground of rainwater, produced a series of problems that influence environment and social development to subterranean infiltration, surface water.For example, the destruction of the aggravation of the pollution of urban groundwater resource and the sedimentation on ground, tropical island effect and the deterioration of city hygrothermal environment, face of land ecotope, aggravation, the city noise of city waterlogging phenomenon ponding serious, non-water-permeable pavement are not only made troubles to the pedestrian, also are easy to bring out traffic accident.At these problems, begin both at home and abroad to adopt seepy material to be used for road pavement, wherein to mat formation be wherein a kind of principal mode to the concrete permeable floor tile, is extensive use of at home at present, its ecological effect and pavement performance are good.But, there is following problems: the one, the reduction of water-permeable behind the life-time service.Hole plug easily takes place in the porousness of existing face brick dankly behind the life-time service, thereby reduces the phenomenon of water-permeable, and this problem is perplexing investigator both at home and abroad, hampers applying of this ecological pavement material; The 2nd, do not possess sufficient moisture storage and stay function.Present water-permeable floor tile is mainly emphasized its water-permeable and air permeable, but it is not enough to stay function to pay close attention to the storage of moisture, and industry standard only requires its water-retentivity to reach 0.6g/cm
2, because the storage of its moisture stays ability less, summer, top course still was in drying regime easily for a long time, the cooling-down effect of evaporation heat absorption is relatively poor.
Three, summary of the invention
In order to solve the problems referred to above of floor tile, the invention provides a kind of floor tile permeable water-retaining agent of water-permeable and water-retentivity preferably that has.
A kind of floor tile permeable water-retaining agent, described floor tile permeable water-retaining agent is formulated by the component of following quality proportioning:
60-70 parts of porous materials
10-20 parts of water-retentivity components
5-10 parts of silicate series cements
1-3 parts of tackiness agent
The particle diameter of porous material should be not more than 0.6mm in the above-mentioned starting material, tap density should be not more than 200kg/m
3, water ratio should be not more than 5%; The water-retentivity component is an absorbent resin, and its granularity is that 150-200m, water-intake rate are not less than 400g/g; Cement is the silicate series cement, and its performance complies with the national standard requirements; Tackiness agent is selected the redispersible polymer rubber powder for use, and its tap density is 400-600kg/m
3, the pH value after the dispersion is that 6.0-9.0, minimum film-forming temperature are 0 ℃.
Among the present invention, the above-mentioned raw materials component feeds intake by the quality proportioning, inserts in the stirrer fully to stir back (such as stirring about 180 seconds) and pour in the plastic containers sealing and preserve.
Further, the optional self-expanding perlite powder of porous material of the present invention, expanded vermiculite powder or zeolite powder etc.
Described water-retentivity component is optional to connect school copolymer analog absorbent resin from polyacrylate(s), polyvinyl alcohol, acetate ethylene copolymer class, polyurethanes or starch, optimization polypropylene esters of gallic acid of the present invention or polyvinyl alcohol absorbent resin.
Described silicate series cement can be selected from silicate cement, ordinary Portland cement, Portland fly ash cement, Portland blast, portland-pozzolan cement etc.
Described tackiness agent can be selected from redispersible EVA rubber powder, redispersible acrylic rubber powder etc.
Beneficial effect of the present invention is embodied in: the floor tile that the present invention obtains can not harden again with the existing filling of permeable water-retaining agent, water retention, has water-permeable and water-retentivity preferably for a long time.This material can be used as the hole weighting agent by prior injection or mix floor tile and can prevent that exotic from stopping up hole, long term maintenance impregnability concrete superperformance.In addition,, can absorb the swelling pressure of water freezing, help the raising of concrete frost resistance because this weighting agent forms flexible configuration in hole.
