Embodiment 1

[0072] A PVC wood-plastic building formwork, the formula of which is shown in Table 1 below.

[0073] A production method of PVC wood-plastic building formwork, comprising the following steps:

[0074] 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.

[0075] 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 cha...

Embodiment 2

[0077] A PVC wood-plastic building formwork, the formula of which is shown in Table 1 below.

[0078] A production method of PVC wood-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.

Abstract

The invention provides a wood and plastic building template and a production method thereof. Reclaimed materials are used for designing a formula, and a production process is optimized according to formula raw material properties. Compared with the prior art, the production method is characterized in that the formula and the dosage proportion of raw materials are controlled to prepare the wood plastic building template, and the wood plastic building template has the advantages of high static bending intensity, high bending elastic modulus, high screw holding strength, flame retardance, good water resistance, acid and alkali resistance, corrosion prevention, energy saving and environment protection, and can be repeatedly recycled.

Description

technical field [0001] The invention belongs to the field of building formwork, and in particular relates to a wood-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] Wood-plastic building formwork is another new generation of 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 and corrosion-resistant. , Good mold release, multiple use, etc. The product adopts crust foaming technology, with high surface smoothness. After concrete pouring, it can meet the requirements of dry wall, and the wall surface does not need secondary plastering treatme...
