Thermoplastic composite board and manufacturing method thereof

Abstract

The invention discloses a thermoplastic composite board and a manufacturing method thereof. The thermoplastic composite board has set lateral width, longitudinally and continuously extends, and is coiled into a roll or is cut into blocks. The thermoplastic composite board comprises an enhanced skeleton, wherein a thermoplastic material layer is covered out of the enhanced skeleton. The manufacturing method comprises the following steps: (1) leveling the surface bend of the continuously-conveyed enhanced skeleton, and carrying out unoiling and derusting processing; (2) heating the enhanced skeleton, coating conglutinant resin material, and forming a binding layer after the conglutinant resin material is solidified; (3) conveying the enhanced skeleton to a formed mould, extruding the thermoplastic material, and successively coating out of the binding layer to obtain the board; and (4) shaping the board to obtain the thermoplastic composite board. The thermoplastic composite board disclosed by the invention has equivalent strength and rigidity and equivalent buffer performance, and can achieve good safety protection effect. The manufacturing method has the advantages of high production efficiency, simple technology and low production cost.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a composite board and a manufacturing method thereof, in particular to a thermoplastic composite board and a manufacturing method thereof. Thermoplastic composite panels are suitable for large site enclosure or traffic enclosure, and are mainly used for the safety protection of livestock breeding, large residential areas, highways, large industrial bases and large entertainment venues. Background technique [0002] In large-scale field enclosure and traffic enclosure, it is necessary to use protective panels or guardrails, such as for livestock breeding in agriculture, large residential areas, highways, bridges, large industrial bases and large entertainment venues such as racetracks, racing tracks, etc. safety anti-collision facilities. [0003] Taking the traffic enclosure as an example, the road anti-collision barriers are mainly used, which are mainly used for the ...

AI Technical Summary

Problems solved by technology

In the guardrail scheme of the above-mentioned steel-plastic composite material, the method of molding and compounding cannot be continuously produced, resulting in low production efficiency; the process of extruding on the surface of the corrugated steel guardrail board is relatively complicated, which increases the cost

More importantly, there is a problem of compatibility between the two materials of plastic steel, resulting in low peel strength between plastic steel and plastic steel, which is easy to be separated during use and installation, so that the strength and toughness of the guardrail board are insufficient and cannot reach The use requirements are not easy to be damaged; and the shrinkage coefficients of plastic and steel materials are different in thermal expansion and cold contraction. After thermal expansion and cold contraction between plastic and steel, there will be relative slippage between the two materials, so that there will be gaps in the joint surface of the two, which will cause Moisture enters from the damaged part of the material surface along the gap of the joint surface to corrode the internal steel, reducing the service life of the guardrail and causing safety hazards

Moreover, the above-mentioned plastic-steel guardrails are all hard guardrails, or because the plastic-steel guardrails are easy to separate and cannot be rolled and bent, it is inconvenient to transport and store, and because the length of the guardrail board is limited, many accessories are required for installation, making the installation cumbersome
