Problems solved by technology

[0003] When the PVC material prepared by the existing preparation method is combined with the metal material, due to the material difference between the plastic material and the metal material, that is, at different temperatures, the expansion and contraction rates are different. Relatively speaking, the deformation rate of the metal Very small, while ordinary PVC has a large deformation rate, which may cause separation between the two materials at different temperatures; and the interfacial surface tension between the two materials is also different, causing problems that are difficult to combine, and the preparation method is complicated. , many additives

Abstract

The invention discloses a preparation method of a PVC composite material for plastic steel. The method comprises the following steps: sequentially adding PVC resin, PC resin, a filling agent, a coloring agent, a compatibilizer, a surfactant, a stabilizer and a lubricant into a high mixing machine, controlling the rotating speed of the high mixing machine to be 1100 to 1650 r / min and the temperature to be 120 to 135 DEG C, adjusting the rotating speed of the high mixing machine to be 700 to 1100 r / min after mixing for 5 to 8 minutes, obtaining a mixed material after mixing for 10 to 15 minutes,and discharging the mixed material; and standing the mixed material for 50 to 80 minutes, cooling to room temperature, adding the mixed material into a double-screw extruding machine, controlling thetemperature of each area of the extruding machine to be 195 to 250 DEG C and the temperature of a machine head to be 240 to 250 DEG C, setting the pressure of melt to be 4 to 9 MPa, performing melt extrusion on the mixed material, cooling and dicing to obtain the PVC composite material. The prepared PVC composite material has strong binding force, small expansion and contraction rate and high strength and can be widely applied in various fields; and the preparation method is simple, the aids are few and heavy metal is avoided.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method for plastic-steel PVC composite materials. Background technique [0002] As the name suggests, plastic steel is a material composed of a combination of plastic and metal. Because in some occasions, the strength of the products processed simply by PVC profiles is not enough; so metal materials are usually added to the cavity of PVC profiles to enhance the firmness of doors and windows, so plastic doors and windows made of steel inside the profiles are usually called Steel doors and windows. [0003] When the PVC material prepared by the existing preparation method is combined with the metal material, due to the material difference between the plastic material and the metal material, that is, at different temperatures, the expansion and contraction rates are different. Relatively speaking, the deformation rate of the metal Very small, while ordinary...
