As it can be seen from table 1 the enhancing styryl composition material of the present invention is as sandwich layer, there is the intensity of excellence, rigidity
Etc. mechanical property, and density is relatively low, only about the half of aluminum alloy materials.
The preparation of enhancing profile shapes:
Use single screw extrusion machine extrusion enhancing styryl composition material as sandwich layer, then stick wood grain in core layer surface
Paper obtains strengthening profile shapes, and results of property is as shown in table 2:
Wherein, described single screw extrusion machine head temperature is 175-195 DEG C, and fuselage one district temperature is 160-165 DEG C, fuselage two district
Temperature is 160-175 DEG C, and fuselage three district temperature is 175-185 DEG C, and fuselage four district temperature is 175-185 DEG C, and screw speed is 18-
22rpm。
Table 2 strengthens each component proportion and the results of property (weight portion) of profile shapes
As can be seen from Table 2, the present invention utilizes woodgrained paper as cortex, and its glossiness reaches more than 90 °, the gloss of relatively aluminium alloy
Degree (about 70 °) is significantly improved, it is possible to provide excellent appearance, high rigidity reinforced styryl composition material is as core
Layer, the serviceabilities such as it can provide the intensity required for bound edge material, rigidity, the two compound enhancing prepared is special-shaped in addition
The thermal conductivity of material is the thermal conductivity (about 200 W/mK) of 0.20-0.30 W/mK, substantially less than aluminium alloy, therefore, the present invention's
Reinforcing profile has lower thermal conductivity, and at insulation, appearance aspect more has advantage.Abnormal shape prepared by the present invention
Material can replace aluminum alloy edge-wrapped material, has preferable application prospect at desk, cabinet, wardrobe bound edge etc..
