Abstract

The invention discloses a YRMC three-dimensional composite sheet, comprising a top film, a mixed material coating and a bottom film sequentially arranged from top to bottom, wherein a glass fiber mesh cloth is arranged inside the mixed coating layer, and the The mixed coating layer is composed of 35% unsaturated polyester resin, 0.5% CaO, 2% MgO, 0.2% zinc stearate, 0.8% low shrinkage additive, 0.1% polymerization inhibitor, 0.4% initiator, 1% crosslinking The resin glass fiber mixture is composed of 60% glass fiber chopped strands, and the resin glass fiber mixture is a sheet-shaped three-dimensional composite formed by interlacing and interweaving with glass fiber mesh cloth by extrusion. The invention can make the pressed product have stronger compression resistance, tensile strength and other excellent mechanical properties. The operation is simple and easy to control.

Description

technical field [0001] The invention relates to the technical field of composite sheets, in particular to a YRMC three-dimensional composite sheet and a production method thereof. Background technique [0002] Compression molding (also known as compression molding or compression molding) is the operation of first putting powdery, granular or fibrous plastics into the mold cavity at the molding temperature, and then closing the mold and pressing it to form and solidify. Compression molding can be used with thermoset plastics, thermoplastics and rubber materials. Composite resin has many advantages. Because of its light weight, strong plasticity, short production time, environmental protection, corrosion resistance, recyclability, and long service life, composite resin sheets are often used as molding materials. [0003] However, the existing composite resin sheets are poor in compressive and tensile properties, resulting in poor mechanical properties of molded products, whic...
