The manufacture craft of anti-skid permeable road mat, is characterized in that step is as follows:
Make bottom: after the rubber grain of monocomponent polyurethane glue and particle diameter 2-5mm is prepared in proportion, putting into mixer stirring mixes both, then pour prefabricated mould into interior and with rake, mixture laying is flat, use again roller compaction, along with the volatilization of glue and rubber grain is dissolving cured is exposed at surface layer and slowly presents relatively concavo-convex hair side outward;
Spraying surface: after treating bottom sclerosis, by the surface layer fine grained compound preparing in proportion and stir, the coarse surface layer with spray gun at bottom surface ejection 1-3mm.
Surface layer has sprayed afterwards, has hardened before at its surface spraying fluorescent material.
The invention has the beneficial effects as follows: road of the present invention pad comprises bottom and surface layer, wherein bottom is by 2～5 millimeters of cementing forming of rubber grain, therefore in structure, there is dispersed micro-pore, surface layer adopts thin rubbery granule spraying to form crude antislip colour layer, there is good water-permeable and air permeable, and good antiskid, wear-resisting, sound-absorbing, the performance such as weather-proof, than the road surface of existing concrete, pitch or ground tile paving, greatly improve the skid resistance under sleety weather condition, eliminated the potential safety hazards such as the easy cunning of ponding; That product has is durable, the performance of acid-alkali-corrosive-resisting, long service life, and coarse elastic surface sound-absorbing and be difficult for airborne dust; Main material is that waste old is processed into, and raw material sources are wide, cost is low, has effectively alleviated and has processed the problem of environmental pollution that waste old produces; Can be according to different communication function needs, the block of making colour or distinguishing with pattern sign, has beautified urban road when having strengthened road diverter function; Also can be on surface layer sprayed with fluorescent powder, when The night screen has hung down, pad upper fluorescent material in road sends faint light, brings vision indication and aesthetic feeling to enjoy to the superincumbent people of walking, also to having increased color the night in city.
The specific embodiment
Embodiment 1: the present embodiment anti-skid permeable road mat comprises black bottom, and be sprayed at the colorful surface layer of this bottom surface, in this example, surface thickness is 1mm; Described surface layer can be according to different communication function needs, the block of making colour or distinguishing with pattern sign, beautifying city road in the time of strengthening road diverter function.
Wherein bottom by the waste black rubber grain of particle diameter 2-5mm and monocomponent polyurethane glue, stirred after cementing forming, thickness can be made the various thickness such as 1cm～5cm on request, and rubber grain and glue weight ratio are 6～7:1.
Cementing forming after surface layer is stirred by following component, the deal of every square metre of product is as follows: particle diameter is 40～80 object rubber powder: 0.07kg, particle diameter is the rubber grain of 0.5～2 millimeter: 0.4kg, color (makes up the deficiency of toner color divergence after dissolving, strengthen the effect of color): 0.08kg, monocomponent polyurethane glue: 0.3kg, fire retardant: 0.03kg.Wherein fire retardant can be that silicon rubber flame-retardant agent, polyurethane flame retardant etc. contain Phosphorus inorganic compound, can also adopt the fire-retardant mode that participates in nonflammable material in colorful surface layer, for example, participate in ceramic powder, quartz sand etc.
Described monocomponent polyurethane glue comprises following raw material, to make this glue 100kg, each raw material consumption is as follows: promoter: 8～21kg, antioxidant: 0.5～1kg, ultra-violet absorber: 0.2～1kg, vulcanizing agent: 0.8～2.5kg, processing aid: 8～62kg, filler: 2.5～19kg, pigment: 0～10kg.
Wherein said promoter is a kind of or any several mixture in zinc oxide, magnesia, Vulcanization accelerator TMTD, captax, accelerant CZ, promoter ZDC, altax, TMTS; Described antioxidant is antioxidant 1010; Described ultra-violet absorber is UV-9 or UV531; Described vulcanizing agent is sulphur; Described processing aid is a kind of or any several mixture in stearic acid, neck dibatyl phithalate, paraffin; Described filler is a kind of or any several mixture in potter's clay, calcium carbonate, white carbon, talcum powder, titanium dioxide; Described pigment is a kind of or any several mixture in iron oxide, iron oxide yellow, the husky Huang of the Chinese.
Described monocomponent polyurethane glue also can be directly at market purchasing finished product, as: the monocomponent polyurethane glue that Hangzhou precious power goods and materials regeneration Co., Ltd produces etc.
In in the pad manufacturing process of described road, also can participate in fluorescent material, when The night screen has hung down, road pad above fluorescent material sends faint light, brings vision indication and aesthetic feeling to enjoy to the superincumbent people of walking, also to having increased color the night in city.
The manufacture craft of the present embodiment is as follows: first make bottom, by design drawing, make mould, after the rubber grain of monocomponent polyurethane glue and particle diameter 2-5mm is prepared in proportion, putting into mixer stirring mixes both in 5 minutes, then pour prefabricated mould into interior and with rake, mixture laying is flat, by small-sized cylinder, be depressed into certain packing, along with the volatilization of glue is exposed at surface layer and slowly presents relatively concavo-convex hair side with rubber grain is dissolving cured outward; Then spraying surface, after treating bottom sclerosis, by the surface layer fine grained compound preparing in proportion and stir, uses high-pressure spray gun at the thick coarse surface layer of bottom surface ejection 1mm.The spraying process time is unsuitable oversize, and in this example, with spraying area zero lap, every 5-6 time second sprays 1 meter of long distance and is advisable; Notice that mix must be evenly simultaneously, guarantee not occur that particle and glue are from rare, and control well and spray out matsurface effect; Finally spray fluorescent material, after surface layer has sprayed, before sclerosis, in its surface spraying fluorescent material (for existing products in markets), can spray by the various lines that design and pattern mode, also can spray comprehensively, form the road pad of an integral fluorescence effect.
In above-mentioned steps, in bottom and surface layer raw material, can add the drier control setting and harden time according to varying environment demand.
On-the-spot laying process: adjust ubbase drain and put slope → ground layer dabbing and clear up → spread glue → road, interface pad and lay assembled.
With reference to the former design draining in road surface thinking, consider road pad and roadbed bonding firmly, utilize small-sized milling machine plane on the ground of intending laying road pad to mill out flocked layer, and rinse the rubbish such as floating grey of cleaning flocked layer, after base cleaning, brush interface glue; The vinyl high strength structure glue that this routine median surface glue can select waterproof binding agent (one-component glue) or architectural bar planting to use; After brushing interface glue, lay prefabricated color road pad, be connected good seam encapsulating everywhere, finally handle being connected of surrounding and drainage system well.Whole work progress is quick and convenient, the duration is short, cost is low.
The requirement of pursuing personalized and urban life landscaping along with people is more and more higher, and the use of color road pad will be a kind of new approaches of future development.
The present invention also can be used for the decoration fields such as the subsidiary sound absorption function of material surface layer of decorative panel.
