Embodiment 1

[0028] The present invention is a kind of industrialized continuous production method of thick and wide building formwork, which comprises the following steps in sequence:

[0029] S1. Mix the plastic material according to the weight of 60-82% waste plastic, 17.5-35% waste rubber and 0.6-12% additives, and first melt and blend the waste rubber and additives, and then Melt and blend it with waste plastics in two twin-screw extruders at a screw speed of 40~45 rpm to obtain molten plastic material. The barrel temperature of the twin-screw extruders is divided into six zones, one zone 120 ~125°C, zone 2 145~150°C, zone 3 165~170°C, zone 4 255~260°C, zone 5 270~275°C, zone 6 285~290°C, head temperature 285~290°C.

[0030] S2. The molten plastic material in each twin-screw extruder is extruded to the same plate extrusion die through different feed ports, and then enters the coat hanger flow channel of the plate extrusion die and merges. Under the action of pushing force, the molten...

Embodiment 2

[0038] The present invention is an industrialized continuous production method of thick and wide building formwork, the production steps of which are similar to those described in the examples, and the only difference from example 1 lies in step S3.

[0039] In this embodiment, in step S3, it is also necessary to embed the fiber net in the blank blank, and the specific steps are:

[0040] S3. The plastic material extruded from the plate extrusion die passes through the gap between a pair of patterned rollers to form a rough blank with texture on the surface, and moves along the direction of the traction device under the traction of the traction device; at the same time, The two groups of fiber webs pre-wrapped on the unwinding machine are unwound under the traction of the traction device, and move toward the traction device through the gap between the pattern rollers in a manner of adhering to the pattern rollers, so that The fiber net is embedded in the prototype blank to for...

Abstract

The invention relates to an industrialized continuous production method of a thick wide-width building template. The production method comprises the following steps of extruding a molten plastic material into a mold opening through a plurality of extruders, adjusting technological parameters of the two-screw extruders and the extrusion mold opening, further compacting a prototype plate with the elasticity by utilizing a calendaring device, and adjusting the thickness of the prototype plate to a needed value, so that the continuous production of the thick wide-width building template is realized. By utilizing the production method, the building template with the thickness of 1 to 8cm and the width of more than 1.2m can be produced.

Description

technical field [0001] The invention relates to the field of building formwork manufacturing, in particular to an industrialized continuous production method of thick and wide building formwork. Background technique [0002] The building templates used in building construction mainly include wooden, bamboo, steel, plastic building templates and composite building templates formed by compounding several of the above-mentioned building templates. Although steel building formwork is strong and has a high number of uses, it is expensive, easy to rust, heavy, and difficult to transport; bamboo and wooden building formwork are light in weight, wide in width, and have few seams, but their strength is relatively low, and they are not moisture-proof and waterproof. It is easy to mildew and rot, and consumes green resources. In contrast, plastic building formwork has the advantages of low cost, light weight, high reusability, stainless, non-stick cement, and waterproof. [0003] The...
