Preferably, it is a kind of preferable substitute materials for wood the advantages that recoverable, is widely used, the density of PVC plastic is larger, process
In extrusion process cause wooden powder density realification, obtained wood plastic composite density is larger, usually 1.2-1.4g/cm
3, larger density to be restricted when it is decorated indoors.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of PVC wood plastic composite decorating board.
The present invention is achieved by the following technical solutions：
A kind of PVC wood plastic composite decorating board, is made up of following component by weight：Polyvinyl chloride resin 120, butyl rubber 1.4-
1.8th, modified polyacetal/ldpe copolymer 5-8, glass fibre 8-12, precipitated calcium carbonate 6-15, wood powder 40-60,
PVC auxiliary agents 1.2-1.8, PVC reinforcer 0.8-1.2, silane coupler 0.2-0.4；
The PVC auxiliary agents are made up of following component by weight：Azodicarbonamide 6, activation sericite in powder 2, sodium acid carbonate
5；
The PVC reinforcer presses 3 by polyacrylate, hydrotalcite：1 mass ratio mixes.
Further, the modified polyacetal/ldpe copolymer preparation method is：By polyformaldehyde, low-density
Polyethylene presses 2：5 mass ratios uniformly after mixing, are extruded on the twin screw extruder, are granulated, and polyformaldehyde/low density polyethylene (LDPE) is common
Polymers；Each section of temperature of extruder be 185 DEG C of an area, 185 DEG C of 2nd area, 190 DEG C of 3rd area, 210 DEG C of 4th area, five 200 DEG C of areas；By poly- first
After aldehyde/ldpe copolymer melting, it is added in high-speed mixer, it is common then adds polyformaldehyde/low density polyethylene (LDPE)
The ammonium persulfate of the fumaric acid of polymers quality 3.8% and its quality 0.22%, mixed at high speed 30min, mixing velocity are
2500r/min, then it is then added in double screw extruder and is granulated, obtains modified polyacetal/low density polyethylene (LDPE) copolymerization
Thing.
Further, the activation sericite in powder preparation method is：Sericite in powder is put into high-speed mixer, heated up
Mixing, when temperature reaches 112 DEG C, 40s is incubated, 2.6% phosphate that dosage is sericite in powder is then put into again, at activation
3.5min is managed, discharge is carried out at 118 DEG C, with 10 DEG C/s speed quickly cooling to room temperature, is produced.
Further, the wood powder is that paulownia wood powder presses 2 with corn stalk powder：5 mass ratios mix.
Further, the preparation method of the PVC wood plastic composite decorating board, comprises the following steps：
(1) wood powder is surface-treated
Wood powder is soaked into 30min in the succinic acid solution that mass fraction is 2.2%, soaking temperature is 40 DEG C, then filters, washes
Wash, then be dried to water content less than 10%, it is standby；
(2) fiberglass surfacing is handled
Glass fibre and titanate coupling agent are pressed 100：After the mixing of 1 mass ratio, it is added in high-speed mixer, is heated to 80
DEG C, 30min is mixed, is taken out standby；
(3) PVC wood plastic clad plate is molded
A is by polyvinyl chloride resin, butyl rubber, modified polyacetal/ldpe copolymer, glass fibre, precipitated calcium carbonate, wood
Powder, PVC auxiliary agents, PVC reinforcer, silane coupler are put into mix to temperature of charge in high-speed mixer by each weight to be reached
During to 105-115 DEG C, add PVC auxiliary agents and precipitated calcium carbonate, continue to mix to temperature of charge reach 118-125 DEG C when, by thing
Material is added in low speed mixer, continue to mix to temperature of charge reach 55-60 DEG C when, carry out discharge material；
In the material input double screw extruder that B discharges step A, tabular fused materials of the extrusion process into different-thickness；
The fused materials that C obtains step B, through stock mould cooling and shaping into sheet material, then by cutting, standard plate is obtained, i.e.,
Can.
The present invention has advantages below compared with prior art：Wood plastics composite decorative panel prepared by the present invention can be smaller compound
The density of material, production cost is reduced, while pass through the collaboration of PVC auxiliary agents and modified polyacetal/ldpe copolymer
Effect, the crack tip of wood plastic composite can be avoided, prevent crack extesion, improve the shock resistance of wood plastic composite
And toughness, that widens wood plastics composite decorative panel of the present invention uses field, improves market value, passes through PVC auxiliary agents and modified poly- first
The synergy of aldehyde/ldpe copolymer, wood plastics composite decorative panel impact property raising 35.2% is enabled to, it is apparent
Density reduces by 28.6%, and shock resistance maximum intensity is improved to 18.22kj/m2, and each composition is not in PVC auxiliary agents prepared by the present invention
It is aobvious with having with performances such as density, bending strength, surface bonding strength and the water sucting thickness expansions for comparing PVC wood plastic decorative panel
The influence of work, optimal proportioning is obtained by many experiments so that each performance of PVC decorative board is effectively improved.
