Abstract

The invention provides a piece of tarpaulin with high strength as well as a preparation method and an application thereof. The tarpaulin with high strength comprises a surface layer, a core layer and a bottom layer; the surface layer and the bottom layer are prepared from non-woven fabrics with resin coated on one side, and the core layer is prepared by a fiber enhanced thermoplastic resin prepreg. The preparation method of the tarpaulin with high strength comprises the following steps: two or more fiber enhanced thermoplastic resin prepreg tapes are laminated and laid on the other side of the non-woven fabrics with resin coated on one side where the resin material is not coated layer by layer in a 0 degree and 90 degrees alternated mode, the other non-woven fabric with resin coated on one side is laid on an uncombined surface of the fiber enhanced thermoplastic resin prepreg tape which is laid at last, so that the other side of the non-woven fabric with resin coated on one side where the resin material is not coated and the uncombined surface are attached, and after post processing, the tarpaulin with high strength is obtained. The tarpaulin with high strength not only has good strength, and has flame retardation, aging resistance, other performances, and long service life; in addition, the preparation method has simple process and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a high-strength tarpaulin and its production method and application. Background technique [0002] At present, the tarpaulins used on trucks in our country are based on polyester staple fiber woven fabrics, which are coated with plastic to make double-sided artificial leather, and then sewn. This kind of tarpaulin has disadvantages such as low strength, heavy weight, rough surface, narrow surface width, easy aging, short service life, poor flame retardancy, low softness, warp and weft breaking tension and elongation rate are not up to standard during use, making the tarpaulin The cloth is easily damaged during use, thereby reducing the service life and increasing the cost of use. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and the main purpose is to provide a high-strength tarpaulin with high strength, light weight, tea...
