Background technology
Domestic early than introducing chinampa the end of the eighties, until the middle and later periods nineties just obtain large-area popularization.It becomes the mode standard that school athletic ground is built together with plastic cement race track, instead of a large amount of athletic ground of originally planting natural lawn.Although due to aspects such as sports safety, place characteristic and public cognitives, the range of application of chinampa is restricted to a certain extent, along with the development of science and technology, the technology of manufacturing of chinampa constantly obtains innovation and improves.
Exercise performance is compared with natural lawn, the usual hardness in place that chinampa is built is much bigger, the friction factor of chemical fibre is also usually less than the blade of turfgrass, just shows as to cause that ball speed is too fast, rebound rate is too high in football, thus increases sportsman to the control difficulty of ball.
The natural lawn of the impact of impact on air regime of environment is made up of green plants, this physiological metabolism process absorbing carbon dioxide of photosynthesis can be passed through, release oxygen, and can the toxic gas such as sulfur dioxide absorption, hydrogen fluoride, ammonia, chlorine, play the effect purified air.There is obvious retardation on natural lawn to dust, and determination data shows, when scraping three moderate breezes, dust concentration aerial in bare area is 13 times of overhead, lawn.Research shows, the carbon dioxide that a people breathes out can all absorb by the lawn of 25 square metres, is converted into oxygen, meets oxygen required in human body respiration process.Chinampa is the non-living matter be made up of the polymer such as polyethylene, polypropylene, can not carry out the metabolic activity of green plants, does not also just have the effect of carbon and oxygen balance in Gas regulation.Normal containing chlorine element impurity in the artificial lawn fiber of low technological level, can decompose under high temperature, strong sunshine condition and discharge chlorine, infringement air quality.
Utility model content
Technical problem to be solved in the utility model is, overcome the shortcoming of prior art, a kind of submissive rhombus monofilament chinampa is provided, the utility model product grass silk is soft, good toughness, elasticity is good, and careless silk plugs firmly, not easily loose or dislocation, effectively can reduce the generation of the athletic injury such as skin tears and foot's bruise.
In order to solve above technical problem, the utility model provides a kind of submissive rhombus monofilament chinampa, comprise the rhombus grass silk that cross section is rhombus, rhombus grass silk plugs in basal layer, basal layer comprises rubber layer, felt layers is provided with below rubber layer, PU bed course is connected below felt layers, the soffit coating gum layer of PU bed course, on the soffit of PU bed course, be provided with pit with the threading position corresponding section of rhombus grass silk, the root place, lower end of rhombus grass silk is provided with anticreep tight loop, and anticreep tight loop is arranged at pit.
The technical scheme that the utility model limits further is:
Aforementioned felt layers is bituminous felt or chemical fibre felt.
Aforementioned anticreep tight loop is rubber ring.
The utility model product is provided with anticreep tight loop at the root place, lower end of rhombus grass silk, and anticreep tight loop is arranged at pit, cluster rhombus grass silk is plugged firmly in basal layer, when not affecting the planeness of lawn entirety, the phenomenon loosen after avoiding lawn Long-Time Service, come off, reduce maintenance cost, increase the service life.
Further,
The utility model also provides a kind of preparation method of submissive rhombus monofilament chinampa, and the preparation method of gum layer comprises following concrete steps:
(1) take raw material according to proportioning, raw material comprises following component according to the mass fraction: natural rubber 62-68 part, hydroxyl butadiene-styrene latex 22-28 part, tackifying resin 48-54 part, triethyl group hexyl phosphoric acid 2-6 part, guar gum 5-7 part, polyacrylate resin 11-13 part;
(2) above-mentioned raw materials is joined reactor, set temperature is 198-212 DEG C, stirs 75-90min, then antioxidant 4-7 part, age resister 3-4 part is added, extend oil 12-18 part, magnesia 7-9 part, zinc oxide 1-3 part, control temperature is 168-176 DEG C, stirs 110-125min;
(3) blend glue stuff is cooled to 150-160 DEG C, blowing, adopts 80-90 object filter screen to filter during blowing, then cool packing, warehouse-in.
The beneficial effects of the utility model are:
The utility model product is provided with anticreep tight loop at the root place, lower end of rhombus grass silk, and anticreep tight loop is arranged at pit, cluster rhombus grass silk is plugged firmly in basal layer, when not affecting the planeness of lawn entirety, the phenomenon loosen after avoiding lawn Long-Time Service, come off, reduce maintenance cost, increase the service life.
The chinampa structure of the utility model design is simple, reasonable in design, cheap for manufacturing cost, and careless silk is soft, good toughness, elasticity is good, grass silk plugs firmly, not easily loose or dislocation, simultaneously, after laying, planeness is better, can fully avoid the field conditions that causes because of the factor such as weather, maintenance bad, thus impact match, and effectively can reduce the generation of the athletic injury such as skin tears and foot's bruise.
embodiment 1
The present embodiment provides a kind of submissive rhombus monofilament chinampa, structure as shown in Figure 1, comprise the rhombus grass silk 1 that cross section is rhombus, rhombus grass silk 1 plugs in basal layer, basal layer comprises rubber layer 2, felt layers 3 is provided with below rubber layer 2, PU bed course 4 is connected below felt layers 3, the soffit coating gum layer 6 of PU bed course 4, on the soffit of PU bed course 4, be provided with pit with the threading position corresponding section of rhombus grass silk 1, the root place, lower end of rhombus grass silk 1 is provided with anticreep tight loop 5, and anticreep tight loop 5 is arranged at pit.
Aforementioned felt layers 3 is bituminous felt; Anticreep tight loop 5 is rubber ring.
The present embodiment product is provided with anticreep tight loop at the root place, lower end of rhombus grass silk, and anticreep tight loop is arranged at pit, cluster rhombus grass silk is plugged firmly in basal layer, when not affecting the planeness of lawn entirety, the phenomenon loosen after avoiding lawn Long-Time Service, come off, reduce maintenance cost, increase the service life.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection domain.
