Embodiment

[0034] Step 1: Auxiliary configuration: according to the weight group, it is 6 parts of calcium zinc stabilizer, 4 parts of external lubricant, 2 parts of internal lubricant, 5 parts of ACR, 5-8 parts of CPE, 1 part of high temperature oxidized wax, 3 parts of coupling agent, 8 parts of plasticizer are used for batching;

[0035] Step 2: Mixing materials: put 5 parts of prepared additives, 125 parts of PVC, 230 parts of calcium powder, and 50 parts of milling material into a mixing machine for mixing to obtain mixed raw materials;

[0036] Step 3: Heat the mixed raw materials to 145°C and then use screw extrusion to plasticize them into SPC substrate boards;

[0037] Step 4: Melt the color film onto the SPC substrate through the rotating hot roller;

[0038] Step 5: Cut into SPC slabs of specified size according to the product length;

[0039] Step 6: Roller paint: Use a paint roller to paint both sides of the PVC paint of the SPC slab, and then use water-based paint to seal...

Abstract

The invention relates to the technical field of building boards, in particular to a flexible SPC board manufacturing process which comprises the steps of auxiliary agent preparation, material mixing, extrusion molding, color film attachment, size determination, painting, foam rubber coating and the like. According to the invention, PVC, calcium powder and ground powder are used as raw materials of the SPC board, after the raw materials are mixed with auxiliaries, extrusion molding is conducted through a screw conveyor, the auxiliaries comprise a calcium-zinc stabilizer, an external lubricant, an internal lubricant, ACR, CPE, high-temperature oxidized wax, a coupling agent and a plasticizer, and therefore the SPC board has the good flexibility, the waterproof performance is good, the extrusion molding process is smooth, heat insulation and fire prevention are achieved, and the SPC board has a good insect and ant prevention effect, is high in production efficiency and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a flexible SPC board manufacturing process. Background technique [0002] With the advancement of industry and the gradual improvement of people's living standards, people's taste for living environment and decoration is also constantly improving. And solid wood composite flooring, in recent years, in response to the national emission reduction, a new type of flooring material, SPC flooring, is produced. This kind of flooring uses calcium powder as the main raw material, after plasticizing and extruding the sheet, Sikun calendering heat-applied color film decoration The layer and the wear-resistant layer do not contain heavy metal formaldehyde and animal substances, and are 100% formaldehyde-free environmentally friendly flooring. [0003] Most of the SPC floors currently on the market have single performance. Therefore, a flexible SPC board manufacturing process is prop...
