Description
Technical field
The present invention relates to a kind of polymer composites to belong to building materials more particularly to a kind of flame-retardant wood-plastic composite board
Field.
Background technique
With rise in oil price, the price of plastic raw materials is also constantly soaring, and plastic industry is all opening up new raw material
Source, including compound plastic board.Wood-plastic composite panel is a kind of composite wood being combined by wood powder and resin matrix
Material, the scale for being able to achieve wood powder utilize.Utilization of the plastic plate in construction industry gradually increases, plastic material product beauty,
Durable, heat preservation, good airproof performance, are favored by people.But wood-fibred is filled into manufactured wood-plastic composite panel in plastics, because
Wood powder water imbibition is strong, and plastics have hydrophobicity, so wood powder and matrix resin poor compatibility, interface cohesive force is small, is melting
Thermoplastic in dispersion effect it is poor, thus poor fluidity, extrusion molding is difficult.And wood powder and plastics easy firing, application
It needs to have wood plastic composite fire-retardant requirement when the fields such as interior decoration, furniture, to reduce the risk of fire.It is existing
Technology is mostly by way of adding fire retardant come fire-retardant, so that the mechanical property of product is greatly reduced, and flame retardant effect
Gradually weaken over time.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of flame-retardant wood-plastic composite board composition, is had using itself
The Corvic of preferable flame retardant effect improves the flame retardant property of material by addition powdered rubber and flame-retardant plasticizer, and
And the presence of powder chlorinated rubber, it is not only cooperateed with flame-retardant plasticizer and improves flame retardant property, but also the precipitation for reducing plasticizer can be played
Performance, to ensure that the intensity and toughness of composite board.
The present invention is achieved through the following technical solutions technical goal, a kind of flame-retardant wood-plastic composite board composition, with weight
Number meter, is made of following component: 100 parts of polyvinyl chloride (PVC), 15-35 parts of wood powder, 5-10 parts of activated Calcium carbonate, calcium zinc are multiple
Close stabilizer 5-8 part, 20-30 parts of flame-retardant plasticizer, 6-8 parts of powder chlorinated rubber, 5-8 parts of ACM-M impact modifier, it is compound resist
1.5~3.5 parts of oxygen agent, 3~5 parts of compounded lubricant.
The polyvinyl chloride is the ethylene process resin that the degree of polymerization is 800-1000.
The wood powder is bamboo powder, is handled using titanate coupling agent, concrete processing procedure is, by titanate coupling agent wine
Essence dilution, alcohol and coupling agent ratio are 5:1, first dry bamboo powder, smash, be then placed in high mixer, stir at low speed, from top
The mixed liquor of alcohol and coupling agent is added in portion's liquid adding hole, mixes 5-10 minutes, alcohol is allowed sufficiently to volatilize.
The aluminate coupling agent and the weight ratio of bamboo powder are 0.5-1.5:100.
The preferred ACM-101 of ACM-M impact modifier.
The flame-retardant plasticizer is tetrabromophthalic anhydride ester, and trade mark BroFlam54-R, amber color liquid is a kind of environment-friendly high-efficiency
Flame-retardant plasticizer has preferable plasticization effect.
The powder chlorinated rubber is product of the synthetic rubber after chlorination modified, and white powder, molecular weight is preferably
5000-10000,60-65% containing chlorine.The chlorinated rubber of lower molecular weight not only can be used as toughener use, but also can pass through chlorination
Other plasticizer are closely linked with Corvic, play the purpose for preventing plasticizer by the effect of rubber,
To improve the flexility of composition.
The lubricant is polyethylene wax, paraffin, three kinds of calcium stearate compound uses, proportions 1:1:1.
The composite antioxidant is the mixture of antioxidant 1010 and DLTP, and the two ratio is 1:1.
The preparation method of flame-retardant wood-plastic composite board composition of the present invention, in turn includes the following steps:
(1) by polyvinyl chloride, activated Calcium carbonate, calcium-zinc composite stabilizing agent, powder chlorinated rubber, flame-retardant plasticizer, compound antioxygen
Agent, compounded lubricant, ACM-M impact modifier weigh in proportion, are added in high-speed mixer, and mixed at high speed 5-10 minutes,
100-110 DEG C of whipping temp, it is put into cooling in low-speed mixer, wood powder is added at this time, continuess to mix 5-8 minutes, releases material；
(2) material mixed is granulated, 150-180 DEG C of prilling temperature, pelletizing in double screw extruder, is packed up to this hair
Bright composition.
Specific embodiment
Present invention is further described in detail combined with specific embodiments below.
Tetrabromophthalic anhydride ester described in embodiment, trade mark BroFlam54-R, amber color liquid, the powder chlorinated rubber are
