Description
Technical field
The invention belongs to wood-plastic door sheet technical fields.More particularly, to a kind of flame-retardant wood-plastic door-plate and preparation method thereof.
Background technology
With the development of society, composite material is widely used in industry-by-industry field.Wherein, Wood-plastic material is compound
One kind of material.Since wood moulding has both two kinds of characteristics of texture of plastics and timber so that it becomes a kind of function admirable and very
Durable outdoor building materials；The Wood member that not only alternative harbour, harbour etc. use, but also made respectively available for substituting timber
Kind packing material, pallet, warehouse pallet etc. are too numerous to enumerate, and purposes is extremely wide.Wood plastic boards, combine plant fiber and plastics are high
The plurality of advantages of molecular material can largely substitute timber, can effectively alleviate the lance that China's Forest Resources are poor, wood supply is in short supply
Shield is a kind of low-carbon of great development prospect, green, is recycled renewable ecological wood-plastic material.
In the prior art, interior door is inflammable when fire occurs and releases a large amount of smog, endangers the life security of people；And
And interior door is also easy to deform in use, formaldehyde and phenomena such as heavy metals exceeding standard, endangers people's health.With
The enhancing of people's environmental consciousness, in order to meet people's demand, a kind of environmental protection flame retardant presses down wood-plastic door in smoke-box and comes into being.
Invention content
In order to solve the above technical problems, first of the present invention is designed to provide a kind of flame-retardant wood-plastic door-plate.
Second object of the present invention is the provision of a kind of preparation method of flame-retardant wood-plastic door-plate.
In order to achieve the above objectives, the present invention uses following technical scheme：
A kind of flame-retardant wood-plastic door-plate, which is characterized in that include the raw material of following parts by weight：Thermoplastic material 50-100

1h is filtered and is washed, and adds in White Mineral Oil, olive oil and glycerin monostearate after vacuum drying, and in 70-78 DEG C, 800-
1000r/min stirs 5h, is washed after filtering dry to get processing aid；
2) fire retardant and lubricant are sent into batch mixer to be mixed and stirred for being heated to 60-80 DEG C, it is first mixed that reaction was completed
Close object；
3) thermoplastic material, plant fiber powder, plasticising conditioning agent, stabilizer, processing aid and foaming agent are sent into
Batch mixer simultaneously is mixed and stirred for being heated to 100-135 DEG C with first mixture, reaction was completed moisture content is 0.5% the
Two mixtures；Barrel is put into after second mixture is cooled to 40-60 DEG C；
4) the second mixture after cooling is put into extruder and is heated to 145-200 DEG C, then squeezed out；The extrusion
145-195 DEG C of machine barrel zone temperature, 155-210 DEG C of mold temperature, engine speed 10-20r/min, feeding rotating speed 10-18r/min；
5) squeeze out after be molded through mold, cooling and shaping, traction, cutting, obtain product.
Further, the rotating speed of the batch mixer is 1400-1600r/min.
Further, step 2) can also carry out according to the following steps：
Thermoplastic material, plant fiber powder, plasticising conditioning agent, stabilizer, foaming agent and modified flame-retardant agent are sent into
Batch mixer simultaneously is mixed and stirred for being heated to 100-130 DEG C with first mixture, reaction was completed moisture content is 0.5% the
Two mixtures；Barrel is put into after second mixture is cooled to 40-70 DEG C.
Further, fire retardant and lubricant are sent into batch mixer and are mixed and stirred for being heated to 60-80 DEG C by the present invention；This be by
In under the conditions of 60-70 DEG C lubricant be in molten condition, lubricant can equably be wrapped in the surface of fire retardant；And then it improves
The dispersibility of fire retardant is conducive to merging for fire retardant and thermoplastic material in later stage mixed process, improves wood-plastic door sheet
Anti-flammability.
Further, the present invention is 15-18min from the time for starting to be fed to needed for final obtained product.
Further, the present invention by thermoplastic material, plant fiber powder, plasticising conditioning agent, stabilizer, processing aid and
Foaming agent is sent into batch mixer and is mixed and stirred for being heated to 100-135 DEG C with first mixture, and reaction was completed obtains moisture content
For 0.5% the second mixture；On the one hand, the second mixture can dissolve completely under the conditions of 100-135 DEG C；Be conducive to second
Fusion reaction occurs for thermoplastic material and other mixtures in mixture, so as to be conducive to wood-plastic door sheet toughness and flame retardant property
It improves；On the other hand, the moisture that can be removed in the second mixture is stirred at such a temperature, makes the control of its moisture in ＜ 0.5%；
So as to improve the intensity of wood-plastic door sheet.
Beneficial effects of the present invention are as follows：
1st, it compared with wood-plastic door sheet in the prior art, is added in the formula of flame-retardant wood-plastic door-plate of the present invention inorganic fire-retarded
Agent, to human body without any harm, flame retardant rating can reach B1 grades, and meeting country will to public place and the fire-retardant of house decoration
It asks.
2nd, not only water absorption rate is low for flame-retardant wood-plastic door-plate of the present invention, indeformable；And in terms of toughness, intensity, nail-holding ability
Higher than national standard, product later stage various processing requirements are disclosure satisfy that.
3rd, flame-retardant wood-plastic door-plate prepared by method using the present invention, it is not only simple for process, but also with stalk, forestry " three
Surplus object " is raw material, and using new formula system, the continuous production period is long, and synthesis is at low cost.The flame-retardant wood-plastic door-plate of the present invention is not

8. a kind of preparation method of the flame-retardant wood-plastic door-plate as described in claim 1 to 7 is any, which is characterized in that including walking as follows
Suddenly：
1) nano zine oxide, nano aluminium oxide and nano silicon dioxide are added in into ultrasonic disperse 10-15min in ethanol in proper amount, so
After add tannic acid, triethanolamine and aluminate coupling agent, and 0.5-1h is stirred with the rotating speed of 200-400r/min, filtering is simultaneously
Washing adds in White Mineral Oil, olive oil and glycerin monostearate, and in 70-78 DEG C, 800-1000r/min is stirred after vacuum drying
5h is mixed, is washed after filtering dry to get processing aid；
2) fire retardant and lubricant are sent into batch mixer to be mixed and stirred for being heated to 60-80 DEG C, reaction was completed obtains the first mixture；
3) thermoplastic material, plant fiber powder, plasticising conditioning agent, stabilizer, processing aid and foaming agent are sent into batch mixing
Machine is simultaneously heated to 100-135 DEG C with first mixture mixing, and reaction was completed obtains the second mixing that moisture content is 0.5%
Object；Barrel is put into after second mixture is cooled to 40-60 DEG C；
4) the second mixture after cooling is put into extruder and is heated to 145-200 DEG C, then squeezed out；The extruder machine
145-195 DEG C of temperature of cylinder, 155-210 DEG C of mold temperature, engine speed 10-20r/min, feeding rotating speed 10-18r/min；
5) squeeze out after be molded through mold, cooling and shaping, traction, cutting, obtain product.
