A multifunctional wood-plastic board fence

Abstract

The invention discloses a multifunctional wood-plastic plate fence. The fence comprises stand columns, the bottoms of the stand columns are fixed to concrete prefabricated parts through bolts, a plurality of fixing parts are embedded in the surfaces of the stand columns, frames are fixedly installed at one sides of the fixing parts, and a plurality of fence plates are fixedly installed on the frames and sequentially connected in a joggled manner; and the frames and the fence plates are wood-plastic composite plates, and the wood-plastic composite plates comprise the following raw materials inparts by weight: 45-65 parts of polypropylene resin, 20-35 parts of ABS resin, 30-50 parts of crop straw, 15-20 parts of graphite, 10-15 parts of TiO2, 3-5 parts of a silane coupling agent and 5-10 parts of a compatilizer. The multifunctional wood-plastic plate fence is large in angle range and suitable for different places, the adopted wood-plastic composite plates are excellent in mechanical property and higher in impact strength and tensile strength, and meanwhile the wood-plastic composite plates have better flame retardance, waterproofness and aging resistance and is higher in weather resistance due to addition of the graphite and the TiO2.

Description

technical field [0001] The invention relates to the field of wood-plastic boards, in particular to a multifunctional wood-plastic board fence. Background technique [0002] Wood-plastic composite board is a kind of wood (wood cellulose, plant cellulose) as the basic material, thermoplastic polymer material (plastic) and processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection new decorative material has both the performance and characteristics of wood and plastic, and is a new composite material that can replace wood and plastic. Wood-plastic composite materials have developed rapidly due to their excellent performance in just a few decades. In recent years, some waste fibers such as straw, straw, corn stalks and other waste fibers have been used to prepare wood-plastic composite materials.

AI Technical Summary

Problems solved by technology

[0003] Fences are generally used as space separators, and can be used for courtyard guardrails in residential buildings, new isolation fences for urban traffic, green area guardrails, etc. The most primitive fence structure is a fence made of bricks, stones and cement, but due to The fence not only occupies a large area and wastes land area, but also lacks transparency, poor aesthetics, inconvenient use, and cannot be dismantled and rebuilt in different places; another kind of fence is often used for temporary space isolation, mainly made of wood and wood Made of screws, the disadvantage is that it wastes wood, it is easy to rot and burn when used in the open air, the service life is limited, and most of them cannot be reused

[0004] Using wood-plastic board instead of cement or wood as a fence can effectively avoid the above problems, but due to the poor adhesion between the fiber component and the polymer component interface of the wood-plastic board, the mechanical properties of ordinary wood-plastic materials are poor, and at the same time The aging resistance of fiber components is poor, and wood-plastic panels are prone to aging and discoloration under outdoor light conditions
