Embodiment Construction

[0017] Production technology of the present invention is as follows:

[0018] (1) Collect plastic bags and similar wastes to be crushed evenly by special equipment, with a particle size of 10-30 mesh, and sawdust or plant straw powder or mixed with it indefinitely, with a particle size of 10-30 mesh, for later use;

[0019] (2) Inclusive treatment is carried out on the surface of sawdust or plant straw powder: add 0.3% of coupling agent, 0.2% of toughening agent, 4% of phase solvent, 1.5% of chlorinated paraffin, and 5% of mixing oil to wood powder by weight percentage , and then mixed in a low speed mixer for 5 minutes, set aside:

[0020] (3) Modification of recycled plastic PE crushed flakes: add 2% PE wax, 1.2% stearic acid, 0.8% stearic acid octyl, and 1% basic lead phosphite to the plastic flakes by weight percentage, and put them into high-speed Mix in a mixer for 5 minutes and set aside;

[0021] (4) Mixing treatment: put the above two raw materials into a large-scal...

Abstract

The present invention discloses a production process for a wood-plastic board and equipment thereof. The production process includes the following steps: (1). Plastic bags and similar waste are collected and crushed uniformly by a special equipment and then mixed non-quantitatively with saw dusts or plant straw powders with granularities from 10 to 30 mesh as a standby; (2). The surfaces of the saw powders or plant straw powders go through a containment treatment. (3). A recycled plastic PE broken piece is modified, (4) mixed, (5) plasticized in an extruder, (6) and formed by pressure. (7) The product is tested and dressed. To complete the process, the special equipments needed are (1) a wood flour drier and (2) a feeding screw of a large-scale extruder. The present product is mainly used for a construction template, a rural sanitary latrine, a detachable mobile simple building, a baffle plate and an enclosing wall in a construction site. The product which is nonpoisonous, unharmful, anti-aging, resistant to shock and source-saving has a strong toughness, a good physical and mechanical property, protects the natural ecology, reduces environmental pollution and makes waste profitable, thus possessing, good social benefits as well as significant economic benefits.

Description

Technical field [0001] The invention relates to a wood-plastic plate production process and equipment thereof, belonging to the technical field of new materials, especially building templates suitable for construction industry. Background technique [0002] The building templates used in my country's construction industry are generally steel molds, bamboo molds and wooden plywood. The former is relatively expensive, and it is easy to bend and deform when removing the mold. Limited by resources, poor strength, low turnover times, and bamboo molds are also limited by resources, most of China does not produce bamboo, inconvenient transportation, no corrosion resistance, no nails, and increased project costs; on the other hand, a large number of waste plastic packaging And the same type of garbage is seriously polluting our living environment. How to remove white pollution and protect forest resources for the benefit of future generations is indeed a problem that people are more a...
