Method for producing thermoplastic composite material and double steel-belt continuous press

Abstract

The invention provides a method for producing a thermoplastic composite material and a double steel-belt continuous press. The double steel-belt continuous press mainly comprises a set of paper and board feed system D, a set of preheating and prepressurizing system C which is arranged on driven rollers at an inlet of the press, a group of driving rollers, a group of driven rollers, and steel belts which are wound on the driving rollers and the driven rollers, wherein the inner part of the press is divided into a heating section A and a cooling section B. Raw materials (core boards and paper) of a product enter the preheating and prepressurizing system C through the paper and board feed system and are combined between the two driven rollers through heating and pressurization, enter the heating section for constant-temperature setting along with the traction of the steel belts, and are cooled and molded through the cooling section to produce finished sheets and strips. The defects of the conventional production machinery for composite boards are overcome; the press has a simple structure and reliable performance, and is relatively low in cost; the finished sheets and strips are pressed by a production process that the internal gluing is not required and the raw materials are combined after being molten; and products in corresponding sizes are processed according to requirements.

Description

[0001] technical field [0002] The invention provides a method for producing thermoplastic composite materials, and also provides a double-steel-belt continuous press for realizing the method, belonging to the technical field of composite plate production machinery. Background technique [0003] At present, most of the composite panel production lines produce production equipment with aluminum-plastic, foam, and metal surface sandwiches as products. The structural combination is mainly divided into heating and cooling sections, and steel strips wrapped symmetrically up and down on the driving roller and driven roller. , as the steel belt runs, the product passes through the heating and cooling sections in sequence, thereby producing a finished plate (a sheet rather than a strip). The main disadvantages of this equipment are: 1. The raw materials for equipment production are sheets or bulk materials (also known as broken materials, which need to be glued and then formed into...
