This non-woven fabrics sheet through increasing wear-resistant material, waterproof material, insulation material and refractory material, has improved the life and the practicality of non-woven fabrics greatly, but extensive being applied to a plurality of fields.
Description
Technical Field
The utility model belongs to the technical field of the non-woven fabrics, concretely relates to non-woven fabrics sheet.
Background
The non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity or irritation, rich color, low price, recycling and the like. For example, the polypropylene (pp material) granules are mostly adopted as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying a line and hot-pressing coiling.
The non-woven fabric has the defects that the surface of the non-woven fabric is easily scratched in the using process along with the continuous expansion of the application field, the practicability and the attractiveness are influenced, and the non-woven fabric is also easily damaged in a high-temperature or humid environment for a long time to influence the service life of the non-woven fabric.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a non-woven fabrics sheet to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the non-woven fabric sheet comprises a non-woven fabric layer, wherein a waterproof layer is arranged on the upper surface of the non-woven fabric layer, a wear-resistant layer is arranged on the upper surface of the waterproof layer, a heat preservation layer is arranged on the lower surface of the non-woven fabric layer, and a fire-resistant layer is arranged on the lower surface of the heat preservation layer.
Preferably, the waterproof layer is made of polyethylene PE material.
Preferably, the heat-insulating layer is a high-efficiency heat-insulating material prepared by coating special interface mortar outside an inorganic fiber core material and a high-gas-barrier composite film through a vacuumizing packaging technology
Preferably, the refractory layer is made of a fiberglass material.
The utility model discloses a technological effect and advantage: this non-woven fabrics sheet has avoided the non-woven fabrics to be lacerated through increasing the wearing layer respectively at non-woven fabrics layer upper surface and lower surface, influences the problem of in-service use, and the setting of waterproof layer, heat preservation, flame retardant coating has improved the non-woven fabrics and has exposed the life in humidity, high temperature environment for a long time greatly moreover, has improved the practicality and the application of non-woven fabrics.
