Description
Technical field
The invention belongs to technical field of polymer materials, particularly relate to a kind of wood moulding PS composite material.
Background technique
For timber as a kind of natural, reproducible resource and Study on Environment Compatible Materials have extensive developing background, gather
Styrene (PS) is a kind of new material of most practical potentiality, it can overcome caused by strength of wood is low, variability is big etc.
Using limitation, and low elastic modulus that can overcome organic material etc. uses disadvantage.
But at present due to technology and timber this body structure, comprehensive utilization ratio is not high.Use toluene diisocyanate
Acid esters (TDI) is reacted respectively with wood powder and nanometer titanium dioxide molybdenum by TDI, is prepared for MoO2/ wood powder material, then PS is carried out
It is modified, a kind of novel wood moulding PS material is made, pertinent literature is simultaneously not found in report.
Summary of the invention
The object of the present invention is to provide a kind of wood moulding PS composite materials, to improve the physical property of PS composite material.
The present invention is achieved by the following technical solutions:
A kind of wood moulding PS composite material, is made of the component of following parts by weight:
The preparation method of the modified wood powder, comprising the following steps:
1) wood powder, toluene di-isocyanate(TDI), dibutyl tin dilaurate and nanometer titanium dioxide molybdenum are weighed；
2) by step it is poly- 1) in each raw material mix after in 80-100 DEG C of oil bath heating reaction 6-10h, product filter；
3) after product filters, the filter cake of acquisition is after acetone extraction, 80-100 DEG C of dry 24- in a vacuum drying oven
36h both obtains modified wood powder.
The wood powder, the toluene di-isocyanate(TDI), the dibutyl tin dilaurate and the nanometer titanium dioxide molybdenum
Mass ratio is 200-320: 3-7: 2-4: 20-30.
The antioxidant is three (2,4- di-t-butyl) phenyl-phosphites, four [β-(3,5- di-tert-butyl-hydroxy phenyl)
Propionic acid] pentaerythritol ester or 1,3,5- trimethyls -2,4, one of 6- (3,5- di-t-butyl -4- hydroxyphenylmethyl) benzene or more
Kind.
The lubricant is the combination of one or both of calcium stearate or stearic acid sodium.
The preparation method of wood moulding PS composite material described in any of the above embodiments, comprising the following steps:
1) 70 parts -90 parts of PS, 1 part -3 parts of HDPE, 20 parts -40 parts of modified wood powder, 0.1 part -0.5 part anti-are weighed
Oxygen agent and 0.4 part -0.8 part of mix lubricant simultaneously stir evenly, and obtain mixture；
2) by mixture extruding pelletization obtained in step 1) to get arrive wood moulding PS composite material.
Preferably, the step 2) specifically: mixture obtained in step 1) is put into the material of double screw extruder
Extruding pelletization in bucket, wherein the double screw extruder includes six humidity provinces sequentially arranged, and the temperature of the first humidity province is
160 DEG C~180 DEG C, the temperature in second temperature area is 180 DEG C~220 DEG C, and the temperature of third humidity province is 180 DEG C~220 DEG C, the
The temperature of four humidity provinces is 180 DEG C~220 DEG C, and the temperature of the 5th humidity province is 180 DEG C~220 DEG C, the temperature of the 6th humidity province
Be 180 DEG C~220 DEG C, the head temperature of the double screw extruder is 180 DEG C~220 DEG C, screw speed be 120r/min~
300r/min。
The beneficial effects of the present invention are:
TDI can not only be reacted with the hydroxyl in wood powder, and can also be carried out with the hydroxyl on nanometer titanium dioxide molybdenum surface
Reaction, such both ends TDI are separately connected fir powder and nanometer titanium dioxide molybdenum, have obtained MoO2/ wood powder material.
For the hydrophily for reducing wood powder after using TDI to be modified wood powder, wood powder and polymer interface are improved
Compatibility, and the dispersibility of wood powder can be improved；And when the use of modified wood powder being filler, on the one hand due to wood powder nano surface
MoO2Large specific surface area, its presence increases wood powder and the contact area of PS, so that the active force between wood powder and PS increases
Add.Nanometer MoO2It is able to enter during mixing in PS matrix, these MoO2Particle becomes stress concentration point, by outer
A large amount of crazing can be generated when portion's active force and absorbs external energy, so that PS composite materials property improves.
