SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a self-adhesion EVA to solve above-mentioned problem.
The technical scheme of the utility model is realized like this: the utility model provides a self-adhesion EVA, includes protective layer, first EVA layer, enhancement layer, second EVA layer, isolation layer, adhesion layer and the release layer that from top to bottom sets gradually, first EVA layer and second EVA layer structure are the same, the enhancement layer includes a plurality of first net layers and second net layer, and is a plurality of first net layer and second net layer are crisscross mutual stack setting in proper order, the adhesion is fixed between first net layer and the second net layer, first net layer includes the first weft that the first warp and the level of vertical setting set up, the second net layer includes the second warp that is 45 degrees contained angles with vertical direction and the second weft that is mutually perpendicular with the second warp.
By adopting the technical scheme, the reinforcing layer can effectively improve the support of the EVA layer, so that the EVA layer is not easy to deform when being subjected to pressure, and the service life is effectively prolonged; the reinforced layer is effectively improved by the first grid layer and the second grid layer to bear the pressure or tension in multiple directions, so that the reinforced layer is not easy to deform and the service life is effectively prolonged.
The utility model discloses further set up to: the protective layer is non-woven fabric.
Through adopting above-mentioned technical scheme, the non-woven fabrics can be effectual protects first EVA layer, has reduced the wearing and tearing on first EVA layer, increase of service life.
The utility model discloses further set up to: the reinforcing layer is made of glass fiber mesh cloth.
By adopting the technical scheme, the glass fiber mesh cloth has good alkali resistance, flexibility and high tensile resistance in the warp and weft directions, so that the supporting effect of the glass fiber mesh cloth on the EVA layer is better.
The utility model discloses further set up to: the isolation layer is vinyl acetate resin.
By adopting the technical scheme, the vinyl acetate resin has higher elongation rate, so that the material can meet the situation of larger change of a base layer, and the use of the material is more flexible.
The utility model discloses further set up to: the release layer is release paper.
Through adopting above-mentioned technical scheme, tear from the adhesion layer and can paste the adhesion layer on the position of needs from type paper, use convenience very.
