Abstract

The invention discloses a preparation method of an environment-friendly high-performance composite material door plate. The preparation method comprises the following steps: 1) coating two sides of asandwich material with epoxy glue; 2) laying a thermoplastic damping material on the two sides of the sandwich material; 3) carrying out continuous fiber prepreg on the surfaces of the thermoplastic damping material to obtain a multilayer laminated body; and 4) placing the multilayer laminated body into a mould, then placing the laminated body in a press machine after the mould is closed, and carrying out lamination for 1-3 hours at a temperature of 100-150 DEG C. The obtained environment-friendly composite material door plate has the advantages of light weight, high strength, excellent soundinsulation performance, excellent bulletproof performance, and no release of formaldehyde. The mass of the door plate is greatly reduced through foam in the sandwich material, and the gaps in the foamhave a good sound insulation function. The thermoplastic damping material polyvinyl butyral (PVB) and ethylene-vinyl acetate (EVA) have excellent damping performance, and have anti-smashing and bullet-proof characteristics, so that the safety of the door plate is greatly improved. The formaldehyde-type adhesive is not needed in a production process, and no formaldehyde is released in a use process of a product, so that the preparation method is safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of decoration materials, in particular to a method for preparing an environment-friendly high-performance composite material door panel. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, people pay more and more attention to the environmental protection and safety of decoration materials. Door panels are widely used in homes, offices, shopping malls, trains, ships and other places. Because people have an affinity for wood, wooden boards are often used. In order to achieve aesthetics and anti-corrosion purposes, wooden boards often need to be painted on the surface in actual use. Wooden boards have some shortcomings, such as easy shrinkage and cracking. Water is easy to deform, easy to mold when wet, easy to burn when exposed to fire, etc. In addition, formaldehyde-based adhesives are generally used in the production process. ...
