Description

A kind of wood is moulded composite fire-proof sheet material
Technical field
The present invention relates generally to a kind of composite material, relates in particular to a kind of wood and moulds composite fire-proof sheet material.
Background technology
Wood plastic composite includes plastics and fiber, therefore, has the similar processing characteristics of same timber, can saw, can follow closely, can dig, and use carpenter's utensil to complete, and nail-holding ability is obviously better than other synthetic materials. Mechanical performance is better than wood materials. Nail-holding ability is generally 3 times of timber, is 5 times of particieboard.
Wood plastic composite includes plastics, thereby has good elastic modelling quantity. In addition, due to including fiber and through fully mixing with plastics, thereby there is the resistance to compression suitable with hardwood, the physical and mechanical properties such as counter-bending, and its durability is obviously better than normal wood material. Case hardness is high, is generally 2 of timber---and 5 times.
Wood-plastic material and products thereof, can anti-strong acid-base, water-fast, corrosion-resistant compared with timber, and does not breed bacterium, is difficult for being damaged by worms, long fungi. Long service life, can reach more than 50 years.
By auxiliary agent, the changes such as plastics polymerization, foaming can occur, solidify, modification, thus change the characteristic such as density, intensity of Wood-plastic material, can also reach anti-aging, antistatic, the particular/special requirement such as fire-retardant.
There is ultraviolet stability, coloring is good. Its great advantage turns waste into wealth exactly, and can 100% reclaiming produce.
Can decompose, can not cause " white pollution ", be real Green Product.
Raw material sources are extensive, and the plastic raw materials of producing wood plastic composite is mainly high density polyethylene (HDPE) or polypropylene, and wood fibre can be wood powder, cavings or wood-fibred, also need in addition a small amount of additive and other processing aids. Can also be as required, make arbitrary shape and size.
Summary of the invention
The object of the invention is just to provide a kind of wood and moulds composite fire-proof sheet material.
The present invention is achieved by the following technical solutions:
A kind of wood is moulded composite fire-proof sheet material, and it is made up of the raw material of following weight parts:
Styrene resin beads 30-40, acrylic resin particle 30-40, wood fibre 60-70, vinyl acetate 2-3, graphite 6-7, magnesium hydroxide 2-4, VTES 1-2,1-ethyl-2-phenylindone 1-2, modification plasticizer 3-4;
Described modification plasticizer is made up of the raw material of following weight parts:
Waste oil 30-40, phthalic acid ester 20-30, castor oil 5-6, jojoba oil 2-3, gamma-aminopropyl-triethoxy-silane 1-2, nano silicon nitride aluminium powder 0.2-0.3, terpene resin 1-2, di-t-butyl peroxide 0.1-0.2, isooctyl acid 0.1-0.2;
Above-mentioned terpene resin is heated to 80-100 DEG C, insulation 10-15 minute, reduction temperature is 50-60 DEG C, add gamma-aminopropyl-triethoxy-silane, dispersed with stirring 3-5 minute, add successively phthalic acid ester, waste oil, castor oil, jojoba oil, after interpolation, rising temperature is 90-100 DEG C, fully stirs, add nano silicon nitride aluminium powder, isooctyl acid, continuing rising temperature is 105-110 DEG C, drips di-t-butyl peroxide, stirring reaction 1-2 hour, be cooled to normal temperature, obtain described modification plasticizer.
Wood is moulded a preparation method for composite fire-proof sheet material, comprises the following steps:
Above-mentioned wood fibre is mixed with vinyl acetate, preheating 10-16 minute at 40-50 DEG C, rising temperature is 60-70 DEG C, adds VTES, 500-600 rev/min of dispersed with stirring 3-5 minute, be cooled to normal temperature, add the each raw material of residue, fully mix, extrude by double screw extruder melt blending, moulding, obtains described wood and moulds composite fire-proof sheet material.
Advantage of the present invention is:
Wood plastic composite surface gloss of the present invention is good, and mechanical property is superior, resistance to compression, and bend resistance performance is strong, and preparation technology is simple, and fire protecting performance is strong, is specially adapted to hot and humid area, safety durable, long service life.
