Antistatic plastic-wood composite board and preparation method thereof

Abstract

The invention relates to an antistatic plastic-wood composite board and a preparation method of the antistatic plastic-wood composite board. The preparation method comprises the steps of mixing wood flour, plastic particles, maleic anhydride grafted plastic particles, glyceryl monocaprate, dodecyl diethanolamine and industrial white oil at high speed, cooling and crushing to obtain plastic-wood composite grains; and then mixing the plastic-wood composite grains, copper powder, stearic amide, talcum and zinc stearate at high speed, and carrying out fusion blending and extrusion forming by adopting an extruder. The antistatic plastic-wood composite board is convenient to produce and manufacture, low in cost, low in consumption of plastic and wood, environment-friendly, high in modulus and rigidity, creep-resistant, and excellent in antistatic effect, can be repeatedly regenerated and does not generate warping deformation. The plastic-wood composite board can be used as outdoor desks and chairs, wooden stools, picnic tables, flower tanks, guardrails, indicators and other products to be widely applied parks, courts, municipal administration and other occasions like the traditional plastic-wood boards, and can also be used in chemical industry, petroleum and other special environments.

Description

technical field [0001] The invention relates to a plastic-wood composite material, in particular to an antistatic plastic-wood composite material plate and a preparation method thereof. Background technique Wood-plastic composite materials use thermoplastics, including polyethylene, polypropylene, polystyrene and their copolymers, as matrix materials, and waste natural fibers such as wood powder, rice husk, wheat straw, corn stalks, and peanut shells as reinforcing phases. , and then add a small amount of chemical additives and fillers, a composite material made through a certain processing technology. It combines the main advantages of thermoplastic polymers and wood, and has the advantages of anti-corrosion, moisture-proof, moth-proof, high dimensional stability, no cracking, no warping, etc. It can be widely used as outdoor flooring, swimming pool edging, flower boxes, tree pools, Fences, trash cans, sun visors, stools, chair strips, backrest strips, leisure tabletops,...

Problems solved by technology

But even so, there are some obvious deficiencies in the use of wood-plastic composite materials. For example, when used in petrochemical areas, it is often necessary for the board or its products to have certain anti-static properties to avoid static sparks. In severe cases, it may even explosion occurs
