What material is spc flooring? The production process of spc flooring

spc flooring is what we often call stone plastic flooring, spc is the acronym for stone plastic composite material in English, it is a flooring made of calcium powder as raw material, plasticized extruded sheet, and mixed in a certain proportion. The production process of spc flooring is not complicated. Calculate the proportion of raw materials and put them into a mixer for hot mixing and cold mixing. After mixing evenly, the finished spc flooring can be obtained after extrusion, UV tempering, slitting and grooving. .

Let's take a look at what material spc flooring is.

is spc flooring? With the development of the flooring industry, there are more and more types of floorings. spc flooring is a new type of flooring. Maybe some friends have heard of it, but they don't know what kind of flooring it is, then spc flooring is a new type of flooring. What is the flooring?

The full name of spc flooring is stone-plastic composite flooring, which is often referred to as stone-plastic flooring. The spc flooring is mainly made of calcium powder as raw material, which is made of plasticized extruded sheets and mixed in a certain proportion. It consists of SPC polymer substrate layer, PUR crystal shield transparent layer, wear-resistant layer, color film decoration layer, soft Silent bounce layer composition.

二、Production process of spc flooring

The following is a brief introduction to the production process steps of spc:

1. Mixing

Automatically measure raw materials such as calcium powder and polyvinyl chloride materials according to the raw material ratio, and put them into a high-speed mixer for hot mixing at a temperature of 125 ° C to mix all kinds of materials evenly and remove the moisture in the materials; In the mixing step, the temperature of the material is cooled to prevent agglomeration and discoloration, and the cold mixing temperature is 55 °C.

2、extrude

The materials that have been uniformly mixed by cooling are added to a twin-screw extruder, heated and extruded, and then entered into a sheet die for extrusion. Stick wear-resistant layer, cooling, cutting treatment.

3、UV tempering

The surface UV technology is used for tempering treatment, and the tempering hot water temperature is 80-120 ℃, and the cold water temperature is 10 ℃.

4. Slitting and slotting

The processed spc flooring is cut, slotted, trimmed, and chamfered. After passing the inspection, it can be packaged and put into the market.
