Polyolefin plastics fibrillation raw material production set special for wood plastic composite material

Abstract

Provided is a polyolefin plastics fibrillation raw material production set special for a wood plastic composite material. A special feed mixer with an automatic feeding, accurate metering and separation system, a plastic extruder with a filtering system, a plastic extruder with a spinning die, a stretcher with a water cooling air purifying system and a special cutting air screen machine form a complete set. The raw material production set can be used for recovering polyolefin plastics or new polyolefin plastics and producing high-quality polyolefin plastic raw materials with a diameter of 0.2-0.4mm, with a length of 2-4mm, comprising functional auxiliary materials of aging resistant agents, pigments and the like required by wood plastic composites, special for fibrillation wood plastic composites and meeting the wood plastic composite processing technology characteristics in an efficient d energy saving way. The mixing technology during the wood plastic composite production process is simplified, the production material cost is lowered, the production device wearing is reduced, the automation degree is raised, the product quality is raised, and the secondary pollution is reduced.

Description

Technical field [0001] The invention relates to a special polyolefin plastic thinning raw material production unit for wood-plastic composite materials. Background technique [0002] Wood-plastic composite material is a new type of material mainly made of plant fiber and waste plastic. As a new, environmentally friendly, low-carbon new material with typical circular economy characteristics, it is in a period of vigorous development in China. Due to the extensive use of plant fiber raw materials such as crop straw and agricultural and forestry miscellaneous materials, the entire industry enjoys the reputation of "afforestation in places without mountains and rivers". As a new material that has just been developed in the past 7-8 years, its production process needs to be improved urgently. The quality of raw materials based on polyolefin waste plastics has become a bottleneck that restricts the further improvement of the final product quality. At present, the polyolefin plas...

Problems solved by technology

[0003] The granules of polyolefin plastic raw materials for wood-plastic composite materials currently used in China are still obtained by the traditional plastic granulation processing technology, and there is no special equipment to provide quality improvement and process improvement for wood-plastic composite materials that meet the processing characteristics of wood-plastic composite materials. High-quality polyolefin plastic raw material
