Abstract

The present invention provides a kind of CPVC of high temperature resistant type (chliorinated polyvinyl chloride) Wood plastic composite, is prepared by following components in percentage by weight:30%CPVC resins, 8 resins of 20%PVCSG, 20% bamboo and woods fiber powder, 10% light active calcium carbonate inorganic filler, 10% modifying agent, 5% processing aid, the above components dispensing is uniformly mixed using high-speed mixer, 1 2h of incorporation time, then double screw extruder squeezes mixed dispensing, cooling and shaping is carried out using the mating mold of double screw extruder, after being handled using dragger, the composite material plank of different length specification is cut into using board cutting machine, it is good that the present invention has targetedly introduced this high temperature resistances of CPVC, the engineering plastics that Ageing-resistant corrosion-resistant is had excellent performance, prepare the CPVC Wood plastic composites of high temperature resistant type, the use deformation temperature of product is made to improve 10 DEG C or more on the basis of routinely modeling wood.

Description

A kind of CPVC Wood plastic composites of high temperature resistant type
Technical field
The invention belongs to composite material plank technical field more particularly to a kind of CPVC of high temperature resistant type (chlorinated polyvinyl chloride second Alkene) Wood plastic composite.
Background technology
The already present Wood plastic composite in existing market, relatively low 70~80 DEG C of high temperature resistant type temperature can not meet outdoor sudden and violent It shines and uses, bow warping often occur, deform, shrink the problems such as serious, influence product normal use.
Therefore, the CPVC Wood plastic composites for inventing a kind of high temperature resistant type are very necessary.
Invention content
For above-mentioned technical problem, the present invention provides a kind of CPV Wood plastic composites of high temperature resistant type, existing to solve Wood plastic composite open air is exposed to the sun use, bow warping often occurs, is deformed, is shunk the problem of serious.
A kind of CPVC Wood plastic composites of high temperature resistant type, are prepared by following components in percentage by weight:30% CPVC resins, 20%PVCSG-8 resins, 20% bamboo and woods fiber powder, 10% light active calcium carbonate inorganic filler, 10% is modified The above components dispensing is uniformly mixed, incorporation time 1-2h, then twin-screw by agent, 5% processing aid using high-speed mixer Extruder squeezes mixed dispensing, and cooling and shaping is carried out using the mating mold of double screw extruder, using dragger into After row processing, the composite material plank of different length specification is cut into using board cutting machine.
Preferably, the double screw extruder head temperature is 176 DEG C.
Preferably, the water temperature of the mold cooling and shaping is 18 DEG C.
Preferably, the double screw extruder extrusion temperature is 165-178 DEG C
Compared with prior art, the present invention has the advantages that:Patent of the present invention mainly for having occurred on the market Wood plastic composite existing for this low defect of high temperature resistant type temperature, targetedly introduced CPVC (chliorinated polyvinyl chloride) This high temperature resistance is good, the engineering plastics that Ageing-resistant corrosion-resistant is had excellent performance, and the CPVC modeling wood for preparing high temperature resistant type is compound Material makes the use deformation temperature of product improve 10 DEG C or more on the basis of routinely modeling wood.
Description of the drawings
Fig. 1 is present invention process flow chart.
Specific embodiment
The present invention is described further below in conjunction with attached drawing:
Embodiment:
As shown in Figure 1, the present invention provides a kind of CPVC Wood plastic composites of high temperature resistant type, by following weight percent The component of ratio is prepared:30%CPVC resins, 20%PVCSG-8 resins, 20% bamboo and woods fiber powder, 10% lightweight active carbonic acid The above components dispensing is uniformly mixed by calcium inorganic filler, 10% modifying agent, 5% processing aid using high-speed mixer, mixing Time 1-2h, then double screw extruder mixed dispensing is squeezed, carried out using the mating mold of double screw extruder cold But it shapes, after being handled using dragger, the composite material plank of different length specification is cut into using board cutting machine.Institute It is 176 DEG C to state double screw extruder head temperature, and the water temperature of the mold cooling and shaping is 18 DEG C, and the double screw extruder squeezes It is 165-178 DEG C to go out temperature, and patent of the present invention is mainly for high temperature resistant type existing for the Wood plastic composite occurred on the market This low defect of temperature, it is good targetedly to have introduced this high temperature resistances of CPVC, the engineering that Ageing-resistant corrosion-resistant is had excellent performance Plastics prepare the CPVC Wood plastic composites of high temperature resistant type, make the use deformation temperature of product on the basis of routinely modeling wood Improve 10 DEG C or more.
Using technical solutions according to the invention or those skilled in the art under the inspiration of technical solution of the present invention, Similar technical solution is designed, and reaches above-mentioned technique effect, is to fall into protection scope of the present invention.
