Abstract
The invention discloses a novel artificial lawn structure which sequentially comprises a lawn bottom cloth layer, a hot-melt type adhesive back-glue layer and a plastic reinforcement layer from top to bottom, wherein the lawn bottom cloth layer is formed by weaving grass on the bottom cloth layer. The invention also discloses a construction method of the novel artificial lawn structure. Compared with the conventional structure taking styrene-butadiene latex as back glue, the novel artificial lawn structure has the obvious advantages in the aspects on pull-out force, creep deformation resistance, oil resistance, wear resistance and service life.
Description
Technical field
The present invention relates to the chinampa field, be specifically related to a kind of novel artificial grassplot structure and building method thereof.
Background technology
Chinampa is that to take lifeless plastics chemical fibre be raw material, the Ecology lawn that adopts manual method to manufacture, it needs to consume the resources such as the essential fertilizer of growth, water as lawn unlike sky, maintenance is simple, and can meet round-the-clock high-intensity motion needs.Therefore, be subject to the restriction of ambient conditions or other factors, in many places of being inconvenient to lay genuine lawn, often lay with chinampa.
The grass silk of chinampa the earliest mostly is the spinning family suedes such as polypropylene, polyethylene and forms, and the base fabric material mostly is natural or synthetic Chinese ephedra or polypropylene material.The grass silk is by the braiding hole weaving on the base fabric surface layer on base fabric, and the connection that forms the pile place by apply one deck bonding adhesive on base fabric is reinforced.The normal bonding adhesive used mostly is carboxylic styrene butadiene latex, but itself smell greatly, the withdrawal force of not environmental protection, grass silk is also very limited, glue face be full of cracks problem easily appears again in the reinforcing face of formation.
The Chinese invention patent application that publication number is CN 102747665A discloses a kind of chinampa, by lawn base fabric, plastic feet with through the plastic expansive rivet that the lawn base fabric is positioned on plastic feet, form, do not use traditional styrene-butadiene latex in structure, solved the problem of thermosetting adhesive to the human injury.But its base fabric and plastic feet structure are only by limited plastic rivet mechanical connection, and grass silk withdrawal force is very limited; And between grass silk and base fabric, do not have bonding adhesive to be reinforced, grass 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 overcome the defect of above-mentioned prior art, a kind of novel artificial grassplot structure and building method thereof are provided, and the structure that this novel artificial grassplot structure and traditional styrene-butadiene latex are made gum is compared and is all being had a clear superiority in aspect withdrawal force, anti-creep, oil resistant, wear-resisting, application life.
For achieving the above object, the present invention adopts following technical scheme:
