Comprehensive analysis of the production process and material structure of SPC stone plastic floor

Stone plastic floor SPC is a new type of environmentally friendly floor developed based on high technology. It has the characteristics of zero formaldehyde, mildew proof, moisture proof, fireproof, insect proof, and simple installation. SPC floor is a product that extrudes PVC base material by extruder combined with T-shaped die, and uses three-roll or four-roll calender to separate PVC wear-resistant layer, PVC color film and PVC base material, and heat lamination and embossing at one time. , The process is simple, the fit is done by heat, and no glue is required. The lock-type SPC stone-plastic floor is in a stage of active promotion and rapid development in the domestic and foreign markets.

SPC floor size

spc floor

Mainly: 1210*150, 1210*181, 203*1219, 178*1219, 152*1219 (unit millimeters)

The main components of SPC floor

PVC resin powder, stone powder, plasticizer, stabilizer, carbon black, the main components are polyvinyl chloride and stone powder.

The structure of SPC floor

The plastic floor is composed of PVC substrate color film decorative paper, wear-resistant layer and UV coating layer from bottom to surface.

Physical properties of SPC floor

Shrinkage rate of SPC floor: ≤1‰ (after tempering treatment), ≤2.5‰ (before tempering treatment), (shrinkage rate test standard: 80℃, 6 hours standard);

SPC floor density: 1.9~2 tons/cubic meter;

Advantages of SPC floor: The physical index of SPC floor is stable and reliable, and the chemical index conforms to international and national standards;

Disadvantages of SPC floor: SPC floor has high density, heavy weight and high transportation cost;

Comparing the production of SPC floor with LVT and WPC floor: The processing and manufacturing process of SPC floor is simple.

Advantages of SPC Eco-friendly Flooring

SPC floor is a new type of environmentally friendly composite material product, and its advantages are as follows:

(1) Waterproof and moisture-proof. It fundamentally solves the problem that wood products are easy to rot, expand and deform after absorbing water in humid and multi-water environments, and can be used in environments where traditional wood products cannot be used;

(2) Insect-proof and termite-proof, effectively eliminate pest harassment and prolong service life;

(3) Colorful, many colors to choose from. It not only has natural wood feeling and wood texture, but also can customize the required color according to your own personality;

(4) It has strong plasticity, can realize personalized modeling very simply, and fully reflect individual style;

(5) High environmental protection, no pollution, no pollution, and recyclable. The product does not contain benzene and formaldehyde. It is an environmentally friendly product. It can be recycled and greatly saves the amount of wood used. It is suitable for the national policy of sustainable development and benefits the society;

(6) High fire resistance. Can effectively flame retardant, the fire rating reaches B1 level, self-extinguishing in case of fire, does not produce any toxic gas;

(7) Good workability, can be ordered, planed, sawed, drilled, and the surface can be painted;

(8) The installation is simple, the construction is convenient, no complicated construction technology is required, and the installation time and cost are saved;

(9) No cracking, no swelling, no deformation, no maintenance and maintenance, easy to clean, saving later maintenance and maintenance costs;

(10) Good sound absorption effect and good energy saving, so that the indoor energy saving is as high as 30% or more;

(11) Compared with LVT and WPC floor, SPC floor has less investment cost, quicker effect, less labor, less labor intensity and clean environment.
