Thermoplastic composite material building template and preparation process thereof and special equipment

Abstract

The invention relates to a thermoplastic composite material building template that comprises 8mm-30mm long glass fiber added in the thermoplastic, and invents a preparation process of the building template as well as special equipment used for implementing the preparation process, thus ensuring that the 8mm-30mm long glass fiber in the thermoplastic composite material building template accounts for 5 percent-60 percent of the weight of the building template. In the building template provided by the invention, the 8mm-30mm long glass fiber accounts for 5 percent-60 percent of the weight of the template, which obviously improves the rigidity/mass ratio and resistance to creep, as well as the stretching, bending and impact properties of the template. Simultaneously, the adoption of thermoplastic leads the building template to be capable of being recovered and renewedly manufactured and processed in damage or in need of other shapes, thus being more environment-friendly and saving more materials. Finally, the addition of inorganic filler can also improve the wearing resistance of the surface of the building template as well as the reuse rate of the template, thus reducing the cost.

Description

technical field [0001] The invention relates to a thermoplastic composite building template. At the same time, the invention also relates to the preparation process of the composite building formwork and the special equipment used in the preparation process. Background technique [0002] At present, three types of building templates are commonly used in the construction field: 1. Wooden multi-layer plywood; 2. Steel formwork; 3. Bamboo board. In addition, there are a few various plastic templates. [0003] There are more or less problems in the actual use of the above-mentioned various templates. Such as poor wear resistance, low stiffness / mass ratio, poor creep resistance, poor fatigue resistance, easy corrosion, difficult demoulding, short service life, non-recyclable, high cost of use and many other disadvantages. [0004] In order to solve many problems existing in the traditional building formwork. Building formwork made of various composite materials has been devel...
