Description
Technical field
The present invention relates to building material field, and in particular to a kind of rice husk composite imitation solid wood board and preparation method thereof.
Background technology
Composite imitation solid wood board is one of a large amount of construction materials for using in modern society's fitment process, with diversity,
Economy, installs facility, and cost-effective, planarization is good, and low-carbon environment-friendly is easy to use, the advantages of comfortableness is good.
However, current composite imitation solid wood board is mostly using wood chip as primary raw material, because current extensive market needs
Derivation causes substantial amounts of wood chip demand, causes to consume substantial amounts of trees every year, and vegetation is caused greatly to destroy, and has run counter to and has worked as premise
The theory of the ecological, environmental protective advocated.Meanwhile, environment is caused secondary containing poisonous and harmful substances such as formaldehyde mostly in existing formula
Pollution.
The content of the invention
In view of this, it is an object of the invention to provide a kind of rice husk composite imitation solid wood board, the composite imitation solid wood board
With rice husk as primary raw material, it is to avoid the destruction caused to environment using wood chip, and the harmful substances such as formaldehyde are not contained.
To achieve the above object, the technical solution adopted by the present invention is as follows：
Rice husk composite imitation solid wood board, is made up of the component of following weight portion：The rice husk of 120-160 mesh is crushed to after drying
20-23 parts, be crushed to 240-270 mesh bentonite 20-25 parts, 0.7-1.2 parts of AC foaming agents, foaming control agent 1.5-1.8 parts,
Polyvinyl chloride resin 145-151 parts, stabilizer 4-7 parts, N, 0.4-0.6 parts of N'- ethylene bis stearamides, glycerin monostearate 0.2-
0.5 part, coupling agent 0.3-0.6 parts, haloflex 5-7 parts.
The rice husk is one layer of shell outside paddy.
The bentonite also known as bentonite, bentonite or amargosite, are the nonmetallic ores with montmorillonite as main mineral constituent
Produce, smectite structure presss from both sides one layer of alumina octahedral is constituted 2 by two silicon-oxy tetrahedrons：1 type crystal structure, due to montmorillonite
There is the work of some cations, such as Cu, Mg, Na, K, and these cations and montmorillonite structure cell in the layer structure that structure cell is formed
With very unstable, easily it is partially or completely exchanged by other cations, therefore with preferable ion exchangeable.Bentonite.
The AC foaming agents have stable performance, it is nonflammable, do not pollute, it is nonpoisonous and tasteless, to mould not burn into product not
The features such as dyeing, decomposition temperature can adjust, not influence solidification and shaping speed.
The foaming control agent has the effect that：Promote the plasticizing of polyvinyl chloride resin；The melt for improving PVC foam material is strong
Degree, prevents bubble from merging；Ensure that melt has good mobility.
The polyvinyl chloride resin is important organic synthesis material, and its product has good physical property and chemical property,
Polyvinyl chloride resin is polarity amorphism high polymer, there is stronger active force between molecule, is a kind of hard and crisp material.
The stabilizer refers to keep the stabilization such as high polymer plastics, rubber, synthetic fibers, prevents it from decomposing and aging examination
Agent.
The coupling agent is also called surface modifier, refers in plastics compounding, to improve synthetic resin and inorganic filler
Or a kind of plastic additive of the interface performance of reinforcing material.
Further, the bentonite by sodium bentonite and calcium-base bentonite according to 4:1 mass ratio composition.
Further, the foaming control agent is hydroxy-ethyl acrylate/copolymer-maleic anhydride.
Further, the degree of polymerization of the polyvinyl chloride resin is 650-700.
Further, the stabilizer is made up of castor oil acid calcium, zinc ricinate and epoxidized soybean oil.
Further, the stabilizer by castor oil acid calcium, zinc ricinate and epoxidized soybean oil according to 4:3:3 mass ratio
Composition.
It, by obtained a kind of chemical products after oxidation processes, is pale yellow under normal temperature that the epoxidized soybean oil is with soybean oil
Color viscous oil-like liquid, is a kind of widely used nontoxic polyvinyl chloride plasticizer and stabilizer：It is good with polyvinyl chloride resin compatibility,
Volatility is low, animal migration is small.With excellent heat endurance and photostability, water resistance and oil resistivity are also good, can assign product
Good mechanical strength, weatherability and electrical property, and it is non-toxic.
Further, the coupling agent is amino silane.
Preparation method the present invention also aims to protect the rice husk composite imitation solid wood board, it is concretely comprised the following steps：
A. by the polyvinyl chloride resin addition batch mixer of above-mentioned mass parts, 125-130 DEG C is heated to, adds above-mentioned mass parts
Haloflex, AC foaming agents, foaming control agent, stabilizer, ethylene bis stearamide and glycerin monostearate, then will be even
Connection agent is sprayed into batch mixer, stirs 16-20min；
B. by the rice husk of above-mentioned mass parts and bentonite addition batch mixer, 25-30min is stirred；
C. step B gained mixtures are stirred at room temperature 10-15min, pour into extruder hopper, existed by extruding machine
Die shaping at a temperature of 180-200 DEG C；
D. by shaping blank Vacuum shaping mould, then draw, then be placed in immersion in water at room temperature and shape for 50-60 seconds, vacuum
Dehumidifying, obtains final product the rice husk composite imitation solid wood board.
Further, polyvinyl chloride resin described in step A is uniformly to be divided into two parts to be divided into add twice, and the coupling agent is uniform
It is divided into three parts and is divided into three penetratings.
The beneficial effects of the present invention are：
The composite imitation solid wood board of the application is with rice husk as primary raw material, it is to avoid use that wood chip causes to environment is broken
It is bad, and do not contain the harmful substances such as formaldehyde.Obtained composite imitation solid wood board flawless, without bubbling, without bulge, without scar, nothing
Joint tongue, corner defect.Surface bonding intensity is high.
