Problems solved by technology

Compared with the previous method, this method has greatly improved the bonding degree of the two layers of materials, but this method is also not suitable for situations where the shape is complex and the edges and corners change greatly, and two sets of molding processing systems are required. Larger total investment
[0008] Yet above-mentioned two kinds of processing methods all can be much stronger than the original way of manual cutting and manual laying, but because both of them all adopt non-environmental protection type PVC as one of compound carpet raw materials, thus these two methods may be used in the production process During the process, due to the escape of harmful gases to varying degrees, it seriously pollutes the environment and affects human health.

Embodiment 1

[0028] (A) The specific composition of composite molding carpet is as follows:

[0029] The fabric layer of the composite carpet sheet is selected as a polystyrene copolymer formed by graft polymerization of styrene monomer and styrene-butadiene rubber. The melt index of the polymer particles is 15, and the weight ratio of styrene to rubber is 85:15. The base material layer is a needle-punched non-woven fabric mixed with polyester fibers and low-melting-point fibers, wherein the weight ratio of polyester fibers and low-melting-point fibers is 70:30, and the surface density of the needle-punched non-woven fabric is 250 g / m2. 250 needles / square centimeter.

[0030] (B) The concrete steps of above-mentioned composite molded carpet manufacture are as follows:

[0031] (1) Add the polymer particles of the fabric layer into the screw extruder with the nozzle of the required composite width, melt at a temperature of 220°C, and extrude the melt into a film with a surface density of 1...

Abstract

The composite formed carpet consists of a facing material layer and a bottom material layer. The facing material layer is made of polymer or mixture of styrene and rubber in the weight ratio of 70 / 30 to 90 / 10; and the bottom material layer is blended needle punched non-woven fabric of polyester fiber and low smelting point fiber in the weight ratio of 60 / 40 to 80 / 20in the needle punching density of 200-400 stitches / sq cm. The production process includes smelting and extruding the polymer for the facing material layer to form a membrane covering the surface of the bottom material layer to combine, far infrared heating, press forming inside mold, cooling to settle, punching, and installing corner parts. The product is environment friendly and erasable, and has high impact strength and less deformation. The production process has short procedure, high efficiency and low cost, and is especially suitable for producing small batch and complicated form carpets.

Description

technical field [0001] The present invention relates to a composite molded carpet and a manufacturing method thereof in the industrial textile manufacturing industry of the textile industry, in particular to a novel composite molded carpet and a manufacturing method thereof. The carpet can be widely used in molding carpets in interior decorations of supporting bodies in automobiles and other fields. Background technique [0002] With the rapid development of the world economy, the continuous improvement of people's living standards, the rapid development of the automobile industry, the production of cars is changing with each passing day, and the models are constantly updated. People's requirements for automobiles are not only beautiful appearance, interior decoration comfort, integrity, and functionality, but also new requirements for the convenience of cleaning the interior of the vehicle, that is, the car carpet is required to be easy to clean and organize. In order to a...
