ACR Materials on PVC Flooring Production

Product Description

characteristics of ACR processing aids 

1. The melting temperature of ACR is lower than that of PVC, and ACR melts earlier than PVC.

2. Because of its good compatibility with PVC, it can adhere to PVC particles after melting during processing, increase internal friction, increase shear torque and generate internal heat, so that the temperature distribution in the material is uniform and the degree of plasticization is uniform, thus promoting the uniform plasticization of PVC materials.

3. The processing aids have enough molecular weight to increase the viscosity (or strength) of the melt, increase the melt pressure and prevent the material from slipping during the processing, so as to increase the shear torque, greatly increase the friction heat between the melt and the metal surface, and promote the mixing uniformity and plasticization degree of PVC mixture.

 

 

PRODUCT INTRODUCTION

ACR processing aid is prepared by graft polymerization  with alkyl acrylate elastomer, which has a "core-shell" structure. Its "core" is a kind of low crosslinking acrylic rubber polymer, and its "shell" is a kind of graft polymer with good compatibility with PVC. Processing ACR is widely used in PVC products in China. The main purpose of processing ACR is to improve the processing properties of PVC. It is usually produced by grafting copolymerization with methacrylate and acrylate. However, the heat transfer and shear force of PVC resin itself are not strong, resulting in uneven melt. ACR modifier can significantly improve the surface gloss of PVC and PVC products.

PRODUCT ADVANTAGE AND DEVELOPMENT PROSPECT

Nowadays, plastic products are popular, plastic materials are constantly developed and applied, and there is a great demand for plastic processing aids. The development of science and technology promotes the progress of the industry. ACR series processing aids are commonly used processing aids, with good thermal stability, aging resistance, improve the performance of the material, improve practicality.

The performance of plastic products has a lot to do with processing aids. The development of high technology has a great help to the plastic material, which improves its performance and becomes a widely used material. Among them, plastic processing aids have been popularized, and more and more kinds of them make it more convenient to improve the material properties.

PACKAGE & TRANSPORT

20KG/25KG polypropylene packaging bags, or customized packagingaccording to customer requirements.
During the transportation and loading and unloading of products, it should be kept clean to prevent sun and rain, high temperature and humidity, and avoid damage to the packaging. It should be stored in a cool, dry, no direct sunlight, temperature below 40 °C warehouse, storage period of two years, after two years after the performance test qualified, can still be used.
 

PRODUCT APPLICATION:PVC Flooring production

What is SPC flooring?

 

SPC stands for stone plastic composite (or stone polymer composite). 

 

SPC flooring is an upgrade and improvement of regular luxury vinyl tiles (LVT), the main content of SPC are natural limestone powder, polyvinyl chloride and stabilizer which combined by a certain ratio to provide us a very stable composite material.

SPC flooring is considered the new generation of floor covering, its features: extremely stability, good performance, completely water-proof, high density solid core, indentation resistance;

It can be easily installed on different types of floor base, either concrete, ceramic or existing flooring;

It formaldehyde free, completely safe flooring covering materials for both residential and commercial area.

SPC core is typically comprised of around 60% calcium carbonate, 20% polyvinyl chloride and 20% other plasticizer chemical materials.

The structure of the SPC floor, from top to bottom are UV layer, Wear resistant layer, PVC decor film, SPC core, and EVA/ IXPE underlay.

Full production processes of SPC flooring

 

 

1. Crushing + Milling

During the SPC production process, it will generate some fragment waste materials. The Crusher and Miller can be used to crush and grind these SPC waste materials into powder, which can be recycled into the raw materials for the production of SPC. The recycled SPC material is also a necessary ingredient in the raw material ratio.

 

2. Mixing

Put the raw materials into a high-speed mixer for hot mixing according to a certain ratio, so that the various materials are mixed uniformly, and the moisture in the materials is removed, and then enter the cold mixer to cool the materials to prevent agglomeration and discoloration. The materials are mixed uniformly by cooling.

 

3. Extrusion

The mixed materials are put into the extruder, extruded by twin cone screw, and formed into sheet shape through the die. Then through four-roller/five-roller calendering unit, the wear-resistant layer and color film are laminated on the sheet by heat, to form the SPC board.

 

4. UV coating

A layer of UV paint is coated on the surface of the SPC board by the UV coating machine, which has the functions of preventing dust, scratching, increasing abrasion resistance, and making the glossy more uniform.

 

5. Cutting

Use automatic multiple ripsaw to cut the big SPC board into the small planks of the required size.

 

6. Slotting

Through the longitudinal and transverse double-end tenoner slotting machine, four sides edges of the SPC plank after cutting are processed into certain lock shape. The important thing is that need to choose the suitable click system and the perfect Polycrystalline diamond (PCD) click profiling cutters.

 

7. V-groove Painting

In global market some customers prefer to the edges of SPC flooring to be V-groove and painted with paint, similar to the edges of laminate flooring.  They think this kind of flooring looks nicer. Of course, this is an optional working process.

 

8. IXPE/ EVA underlay laminating

Use hot melt adhesive to stick IXPE /EVA underlay on the back of the SPC flooring, which can make the flooring have better sound insulation effect and better walk feeling. Such products are more high-end.

 

9. Packing

Choose packing machine with different degrees of automation according to your needs, and there are fully automatic and semi-automatic machines can be optional.
