Problems solved by technology

[0002] Existing walkway slab materials (such as railway pedestrian maintenance roads, garden landscape plank roads, platforms, etc.) generally use materials such as cement and wood structures (such as plastic wood, etc.), which have the following defects and deficiencies: 1. The cement material The road slab has poor water permeability and poor impact resistance. If it is placed outdoors, it is easy to cause cracks and cracks due to various weather conditions.
In addition, due to the strong thermal expansion and contraction ratio of cement, it is troublesome to deal with cracks, the service life is low, and the maintenance cost is high; 2. The road board made of wooden structure material is easy to corrode, insects, flammable, poor fire resistance, and weather resistance Insufficient, poor insulation in wet weather conditions, etc.

specific Embodiment

[0034] High-temperature curing stretching process: under the action of traction, the continuous roving, felt, tape or cloth soaked in glue is heated, extruded, pultruded and solidified through the mold to continuously produce unlimited lengths. Polymer composite profiles.

[0035] 1. Raw materials and ingredient ratios for high temperature curing stretching process

[0036] (1) Reinforcement material

[0037] The reinforcing material of high temperature curing stretching process is mainly polymer fiber and its products, such as roving, glass fiber mat and aramid fiber, carbon fiber, ultra-high molecular weight polyethylene fiber and basalt fiber, etc.; the proportion is the weight percentage of the product About 45% to 60%;

[0038] (2) Resin matrix

[0039] In the high-temperature curing stretching process, unsaturated polyester resin, epoxy resin, vinyl resin, thermosetting methacrylic resin, modified phenolic resin, flame-retardant resin, polyurethane resin, etc. are sel...

Abstract

The invention relates to a macromolecular composite plate and a preparation method therefor. The composite plate is prepared by adopting a high-temperature curing and drawing process. The prepared macromolecular composite plate is sequentially provided with a surface felt reinforcing material layer I, a reinforcing sandwich layer and a surface felt reinforcing material layer II, wherein a resin matrix layer, a macromolecular fiber material layer, a resin matrix layer and a macromolecular fiber material layer are sequentially arranged between the surface felt reinforcing material layer I and the reinforcing sandwich layer, and a macromolecular fiber material layer, a resin matrix layer, a macromolecular fiber material layer and a resin matrix layer are sequentially arranged between the reinforcing sandwich layer and the surface felt reinforcing material layer II. The macromolecular composite plate is prepared through fiber-interwoven weaving and resin-pouring integral mold pressing and has maximum corrosion resistance; the overall structure load of the composite plate is more uniformly distributed, so that mounting and uniform stress of a supporting structure of the composite plate are facilitated; and the macromolecular composite plate has the comprehensive economic benefits of corrosion resistance, light weight, high strength, flame retardance, shock resistance, fatigue resistance and the like.
