Problems solved by technology
[0003] However, due to commonly used thermoplastics such as polypropylene, polyethylene, polyurethane, polystyrene and polyvinyl chloride, there are common deficiencies such as poor rigidity, low bearing capacity, and poor bending pressure.
Its mechanical, physical and chemical properties are far from meeting the requirements of plates used in automobiles and other transportation vehicles, military engineering, etc., thus restricting the lightweight development of automobiles and other transportation industries

Abstract
The invention discloses a non-natural continuous filament fabric reinforced low-density pre-foamed plastic sheet, which comprises a first thermoplastic polypropylene plastic and thermoplastic low-density polyethylene plastic blended modified pre-foamed plastic layer (1), a non-natural continuous filament fabric layer (2) and a second thermoplastic polypropylene plastic and thermoplastic low-density polyethylene plastic blended modified pre-foamed plastic layer (3), wherein the three layers are co-extruded to form the low-density pre-foamed plastic sheet. The low-density pre-foamed plastic sheet has the characteristics of good mechanical and physical properties, light weight, low cost and the like and is recyclable. Products compounded by a plurality of layers of the low-density pre-foamed plastic sheet can be used as an automotive roof, a wind scooper and the like.
Description
technical field [0001] The invention relates to a non-natural continuous filament fabric reinforced low-density pre-foamed plastic sheet, in particular to a reinforced plastic sheet for preparing a reinforced composite plastic sheet by multi-layer thermoplastic compounding. It belongs to composite material technology. Background technique [0002] At present, high-strength nylon, PC, polyoxymethylene, polysulfone, polyether and other products, glass fiber reinforced plastic products and various plastic alloy engineering products and their plates have been used in various industries such as electronics, machinery, construction, automobiles and other transportation vehicles. It is widely used in the field of industrial and daily necessities, and has achieved outstanding achievements. [0003] However, due to common thermoplastics such as polypropylene, polyethylene, polyurethane, polystyrene, and polyvinyl chloride, there are common deficiencies such as poor rigidity, low bea...
