Production technology and material structure of SPC flooring

SPC flooring (full name Stone plastic composites flooring) is a new type of environmental protection flooring developed based on high technology. It has the characteristics of zero formaldehyde, mould proof, moisture-proof, fire-proof, insect proof and simple installation. SPC flooring is a kind of product made of PVC base material extruded by extruder combined with t-mold, then, heat and press the PVC wear-resistant layer, PVC color film and PVC base material respectively by three roll or four roll calender at one time. The process is simple, and the lamination is completed by heat without glue.

The SPC flooring of lock catch type is in the active promotion and rapid development stage in the world market. Now this article analyzes the production technology and material structure of SPC flooring.

Dimensions of SPC flooring: 1210*150, 1210*181, 203*1219, 178*1219, 152*1219 (mm)

Main components of SPC flooring: PVC resin powder, stone powder, plasticizer, stabilizer, carbon black, the main components are PVC and stone powder.

Structure of SPC flooring: From the bottom to the surface, the SPC flooring is composed of PVC base material, color film decorative paper, wear-resistant layer and UV coating.

Physical properties of SPC flooring: Shrinkage ≤ 1 ‰ (after tempering), ≤ 2.5 ‰ (before tempering), (shrinkage test standard: 80℃, 6 hours).

Density of SPC flooring: 1.9-2 T/m³

Advantages of SPC flooring: The physical indexes of SPC flooring are stable and reliable, and the chemical indexes meet the international standards.

Disadvantages of SPC flooring: It has high density, heavy weight and high transportation cost.

Comparison with LVT, WPC flooring: Processing and manufacturing technology of SPC flooring is simple.

Environmental protection SPC flooring has the following advantages:

(1) Waterproof and moisture-proof. The problem of wood products which are easy to rot and distort after absorbing water and moisture in humid and multi water environment is solved. It can be used in the environment where traditional wood products can not be used;

(2) It can prevent insects and termites, effectively prevent insect harassment and prolong service life;

(3) Colorful, many colors can be selected. It has natural wood feeling and wood texture, and can customize the color according to its own personality;

(4) It is very plastic, can realize the personalized modeling very simply, fully reflect the personality style;

(5) It is environmentally friendly, pollution-free, pollution-free and recyclable. The products are not containing benzene and formaldehyde, can be recycled to save the wood use, and are suitable for the national policy of sustainable development, and benefit the society;

(6) High fire resistance. It can effectively flame retardant, and the fire rating reaches B1, and it will extinguish itself in case of fire, and no toxic gas will be produced;

(7) It has good processability, can be ordered, planed, sawable, drillable and painted on the surface;

(8) The installation is simple, the construction is convenient, and it does not need complicated construction technology, and saves the installation time and cost;

(9) It is not cracked, expanded, deformed, and needs no maintenance and maintenance, so it is easy to clean and save the maintenance cost in the later period;

(10) Sound absorption effect is good, energy saving is good, so that indoor energy saving is up to 30%;

(11) Compared with LVT and WPC flooring, SPC flooring has less investment cost, faster efficiency, less labor, less labor intensity and clean environment.
