Problems solved by technology

However, this patent does not disclose any slip agent composition, and it is prone to the problem of wheel sticking in the calendering process; and the patent adds 20-50 parts of calcium carbonate to 100 parts of polyolefin main body, which will be unfavorable to the foaming process Impact
In addition, this invention still does not solve the problem of adhesion to heterogeneous materials, so its product does not have a fabric layer and cannot be applied to artificial leather

[0041] fabric preparation

[0042] Take a woven fabric blended with rayon and polyester, apply a layer of adhesive with a 40-mesh roller coating device, and dry it in an oven at 90°C.

[0043] Preparation of foam layer

[0044] Take the melt index (meiltindex, hereinafter referred to as MI) as 5 and the density as 0.865g / cm 3 Polyethylene elastomer (Engage(R) 7447) 70% with a MI of 1.6 and a density of 0.897 g / cm 3 30% of polyethylene elastomer (Engage ® 8440) is used as the base resin, and 10 parts by weight of EVA resin (Superplastic ® UE 659, vinyl acetate content 25%) is mixed with respect to 100 parts by weight of the base resin. 5 parts by weight of EMA resin (Elvaloy 1218AC, methyl acrylate content 18%), 5 parts by weight of ADCA (Azodicarbonamide, azodicarbonamide) blowing agent (Otsuka Chemical AZH), 0.6 parts by weight of stearic acid Zinc, 0.2 parts by weight of ethylene-bisstearamide (Kao EBS), 0.5 parts by weight of polyethylene wax, 10 parts by weight of ca...

Embodiment 1

[0048] Example 1-leather (Figure 2)

[0049] On a calender, the formed surface layer (2) is attached to the pre-adhesive fabric (1), and then passed at a speed of 16 yards per minute at a temperature of 200°C, 190°C, and 190°C. and an oven at 165°C, and then the rubber is passed through an embossing device composed of two rollers, and finally cooled and coiled.

Abstract

The invention discloses a rolling method to make polyolefin elastomer leatheret, which is characterized by the following: adding fitful functional modified material to improve its radiofrequency welding property and adhesion of polar material; adopting polyolefin elastomer as main raw material; adding lubrication prescription composition and foamer composition into fusing course; using roller to extract rubber cloth after high temperature gelatination; applying base cloth disposed by adhesion agent; processing the elastic product under high temperature; adding functional copolymerization resin in the formulation to increase radiofrequency fusing property of the product.

Description

technical field [0001] The present invention relates to a method for manufacturing polyolefin elastomer (polyolefin elastomer, POE for short) artificial leather using a calendering process, and the artificial leather product prepared by the method. Background technique [0002] The basic composition of artificial leather is a layer of fabric, and a layer of soft plastic film is pasted on the fabric. The fabric can be made of one of cotton, hemp, rayon, nylon, polyester, polyethylene, polypropylene, acrylic, etc., and the soft plastic can be any soft-touch, plasticized or unplasticized plastic material. Sometimes, in order to obtain better tactility, heat preservation, shockproof, etc., a foaming layer is added between the fabric and the film. The foaming layer can use the same base material as the film layer, or it can be a different material compatible with the film layer. . In specific applications such as high-frequency welding processing, the fabric will affect the fu...
