Embodiment 1

[0069] A kind of PVC building formwork, its formula is as follows table 1.

[0070] A production method of PVC building formwork, comprising the following steps:

[0071] 1. Through the automatic batching system, the required materials are automatically measured according to a certain formula ratio, and then put into the thermal mixer for mixing. During the thermal mixing process, the moisture in the mixture is fully removed by thermal mixing, and the materials are in the thermal mixer. Mix for 400-500 seconds, discharge into the cold mixer after reaching the process temperature of 110°C, cold mix for 300-400 seconds, remove foreign matter at 45°C by Roots blower and vibrating screen, enter the storage tank, and homogenize for 24 hours.

[0072] 2. After the powder mixture enters the extruder from the hopper on the extrusion line, with the continuous movement forward and the temperature change during the extrusion process, the material slowly changes from solid to viscous flui...

Embodiment 2

[0074] A kind of plastic building formwork, its formula is as follows table 1.

[0075] A production method of a plastic building formwork, the steps are the same as in Example 1, and the parameters of the extruder are controlled in the following table 2.

[0076] Table 1:

Abstract

The invention provides a plastic building template and a producing method thereof. The plastic building template uses reclaimed materials, designs formula, and optimizes productive technology according to formula property, compared with the current technology, the prepared plastic building template through controlling ingredients formula and dosage ratio is of high static bending intensity, high bending of elasticity modulus, strong power of gripping screw, inflaming retarding, good water resistance, acid and alkali resistance, corrosion protection, can be recycled repeatedly, save energy and protect environment.

Description

technical field [0001] The invention belongs to the field of building formwork, and in particular relates to a plastic building formwork and a production method thereof. Background technique [0002] The building formwork is used to support and shape the concrete after it is poured. Building formwork is generally divided into wood formwork, plastic formwork, steel formwork, bamboo plywood, etc. according to the nature of the material. [0003] Plastic building formwork is another generation of new products after wood formwork, steel formwork, and bamboo plywood. It is a new type of environmentally friendly building material that replaces wood and steel with plastic and saves energy. It is recyclable, corrosion-resistant, It has the advantages of good mold release and repeated use. The product adopts the crust foaming process and has a high surface smoothness. After concrete pouring, it can meet the requirements of dry wall, and the wall surface does not need secondary plast...
