The invention discloses a kind of novel artificial grassplot structure, it comprises lawn bottom cloth layer, hot-melt adhesive gum layer, plastic consolidation layer from top to bottom successively, and described lawn bottom cloth layer is knitting grass silk on bottom cloth layer; The invention also discloses the building method of above-mentioned novel artificial grassplot structure.All have a clear superiority in withdrawal force, resistance to creep, oil resistant, wear-resisting, application life compared with the structure that novel artificial grassplot structure of the present invention and traditional styrene-butadiene latex make gum.
Description
Technical field
The present invention relates to chinampa field, be specifically related to a kind of novel artificial grassplot structure and building method thereof.
Background technology
Chinampa is for raw material with lifeless plastics chemical fibre, adopt the Ecology lawn that manual method manufactures, it needs to consume the required resource such as fertilizer, water of growth unlike sky as lawn, and maintenance is simple, and can meet the motion needs of round-the-clock high strength.Therefore, be subject to the restriction of ambient conditions or other factors, be inconvenient to the place of laying genuine lawn many, often lay with chinampa.
The careless silk of chinampa mostly the earliest is the spinning such as polypropylene, polyethylene race suede and forms, backing material mostly be natural or synthesis Chinese ephedra or polypropylene material.Grass silk is by the braiding hole weaving on base fabric surface layer on base fabric, and the connection forming pile place by applying one deck bonding adhesive on base fabric is reinforced.The bonding adhesive of normal use mostly is carboxylic styrene butadiene latex, but itself smell greatly, not environmentally, the withdrawal force of careless silk is also very limited, and be full of cracks problem in glue face easily appears again in the reinforcing face of formation.
Publication number is that the Chinese invention patent application of CN 102747665A discloses a kind of chinampa, be made up of lawn base fabric, plastic feet and the plastic expansive rivet that is positioned on plastic feet through lawn base fabric, do not use traditional styrene-butadiene latex in structure, solve the problem of thermosetting adhesive to human injury.But its base fabric and plastic feet structure are by means of only limited plastic rivet mechanical connection, and careless silk withdrawal force is very limited; And not having bonding adhesive to reinforce between careless silk and base fabric, careless silk withdrawal force is very limited, and the application life of chinampa is low.
Summary of the invention
The object of the invention is to the defect overcoming above-mentioned prior art, a kind of novel artificial grassplot structure and building method thereof are provided, all have a clear superiority in withdrawal force, resistance to creep, oil resistant, wear-resisting, application life compared with the structure that this novel artificial grassplot structure and traditional styrene-butadiene latex make gum.
For achieving the above object, the present invention adopts following technical scheme:
A kind of novel artificial grassplot structure, it comprises lawn bottom cloth layer, hot-melt adhesive gum layer, plastic consolidation layer from top to bottom successively, and described lawn bottom cloth layer is knitting grass silk on bottom cloth layer.
Hot-melt adhesive has a lot of advantage compared with traditional solvent-borne bonding adhesive.First, not containing solvent, nonpoisonous and tasteless, meet environmental requirement; Secondly, peel strength is high, and adhesion stress is strong, with the obvious advantage for the withdrawal force of grass silk during chinampa; Again, hot-melt adhesive and chinampa grass wire material performance is similar, and after construction, the persistence of adhesive surface is good, and there will not be come unstuck, the problem of glue face be full of cracks; Last hot melt adhesive can Reusability, and as there is local process defect after chinampa paving glue, the mode by reheat correction of the defect is repaired, easy and simple to handle, practical.
In order to improve the ambient adaptability of chinampa, reducing the cost that hot-melt adhesive uses in chinampa, below artificial turf back glue-line, designing one deck plastic consolidation layer.Plastic consolidation layer can high, very strong PE, PP material of property or pliability is good, elasticity is high EVA the material of selection intensity.
The melt index of described hot-melt adhesive is issued to more than 120g/10min in 120 DEG C/2.16Kg condition, hot-melt adhesive is enable to penetrate into braiding place by the braiding hole on bottom cloth layer, good wellability, caking property is all had to the careless silk such as polyethylene, polypropylene, enhance the adhesion between careless silk and base fabric, improve careless silk withdrawal force.
