Abstract
The invention provides a production method of a PVC decorative board, and solves the technical problems that the conventional decorative board has too simple components, has no antistatic and anti-aging properties, has a single function and the like. The production method of the PVC decorative board comprises the following steps: a, preparing materials: firstly putting a PVC powder, paraffin, stearic acid and active heavy calcium carbonate into an ordinary stirrer, stirring for 20min at the speed of 680r / min, then adding remaining raw materials, then stirring for 11min at the speed of 450r / min, controlling the temperature to 120 DEG C, and preparing a mixed material; b, performing vacuum heat treatment: performing vacuum heat treatment in a vacuum medium with the vacuum degree of 0.9Pa, and then naturally cooling, wherein the heat treatment temperature is 220 DEG C and the heat treatment time is 40min; c, moulding: putting the mixed material in the step b into a mould, putting the mould into a 55 DEG C thermostat, standing at constant temperature for 2h, demoulding to obtain a board with the thickness of 7m, and airing the board by using airing equipment, wherein the airing temperature is 33 DEG C and the airing time is 40h. The PVC decorative board has the advantage of strong functionality.
Description
technical field [0001] The invention relates to a production method of a PVC decorative board. Background technique [0002] PVC decorative board has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardancy, and simple construction. It has various specifications, colors, and patterns, and is very decorative. One of the most widely used decorative materials in materials. [0003] After searching, for example, Chinese patent literature discloses a PVC fiber synthetic wall and floor decorative board [application number: 201610043074.2; publication number: CN 105507530A]. This PVC fiber synthetic wall and floor decorative board is characterized in that: the PVC fiber synthetic wall and floor decorative board formed by extrusion or injection molding is used as the carrier, the bottom of the decorative board extends to the right and the protruding edge is the pressing edge, and the decorative board faces left. The extended si...
