Method for producing high-strength composite plastic template

Abstract

The invention relates to a method for producing a high-strength composite plastic template which comprises an upper and a lower composite layers and a core layer. The method for producing the high-strength composite plastic template comprises the following steps: loading the core layer raw material into a high-speed mixer to be mixed, feeding the mixed material into a twin-screw extruder by a feeder, extruding the extruded material into a core layer extruder, feeding the raw materials of the composites layers to a plastic extruder, extruding the extruded core layer raw material, the upper and lower composite layer raw materials into a mould, clamping the two or more layers of glass mats (fiber cloth, fiber mesh cloth and aluminum plates) into the raw material by the mould, cooling and cutting the template into the finished product by using embossing or forming equipment. The invention ensures that the plastic template can be formed into various patterned flat plates and specially-shaped templates in one time, overcomes the defects of wasting resources, manpower and material when secondary processing the steel template and the wooden template, saves the resources and reduces the cost. The plastic template can be provided with any shape and pattern according to the need to make the building be in stronger stereoscopic impression. Because the olefin plastic is inorganic material which is difficult to bond with any material, the surface of the made wall is smooth and even and is easy to demould, but the surface of the wall is difficult to bond with other materials during the building decoration. The surface of the plastic template can be provided with smaller patterns to form a pitted surface for use in the building so that the adhesion force of the surface of the wall and the decorative material can be greatly improved when the surface of the wall is decorated. Compared with the similar product, the composite structure product has higher rigidity and toughness.

Description

technical field [0001] The invention relates to a method for manufacturing a high-strength composite foamed plastic template used in the construction field. Background technique [0002] At present, the building templates used in various construction fields are mainly steel material templates and wooden material templates. Although steel formwork has been widely used in past projects, the processing technology is difficult to shape, the cost is high, the weight is heavy, and the waste of materials is serious. The wooden formwork is a formwork made of wood. Although it is light in weight, it cannot be made into a special shape and is easy to break. After a few times of use, it will be glued and layered and cannot be used, resulting in a large waste of wood and greatly increasing the construction cost. hazards to the environment and humans. Contents of the invention [0003] Based on the above problems, the purpose of the present invention is to use waste plastic waste (al...
