Preparation process of light fiber reinforced thermoplastic plate for shielding curtain

Abstract

The invention provides a preparation process of a light fiber reinforced thermoplastic plate for a low-odor low-VOC high-strength shielding curtain. The plate comprises a fabric layer, a hot melt adhesive film, fiber reinforced thermoplastic resin felt, a hot melt adhesive film and a fabric layer which are sequentially arranged from top to bottom and is prepared by combining a continuous rolling device and a thermal radiation heating or hot plate heating mode. The prepared plate is the light fiber reinforced thermoplastic plate for the shielding curtain and is uniform in thickness, flat in appearance, high in strength, low in odor and low in VOC.

Description

technical field [0001] The invention relates to the field of composite materials for automobile interior decoration, in particular to a preparation process of a lightweight fiber-reinforced thermoplastic plate for a curtain. Background technique [0002] Car curtains are a common interior component in various types of cars. They are mainly used in car trunks and have two main functions: (1) Improve the safety of the car process. The covering curtain plays a role in isolating the items stored in the trunk. During the driving process of the car, it can prevent the items from jumping into the occupant space and cause safety hazards; (2) Energy saving and beautiful appearance. Covering the items in the trunk improves the cleanliness and aesthetics of the vehicle, saves space for heating and cooling of the air conditioner, and reduces energy consumption. [0003] At present, there are three main types of vehicle blinds on the market: wood powder board, cardboard and fiber reinfo...

[0005] The related invention patents, CN 107722915 A and CN107815864A, introduced light, environment-friendly and low-odor automotive shades and their preparation methods, with 300-700g / m 2 The water-based adhesive is used as the bonding material between the surface of the fiber-reinforced thermoplastic board and the non-woven fabric. The non-woven fabric has been treated with antibacterial agents to reduce the VOC and odor of the curtain to a certain extent. The effect of improving the odor and odor is limited, and it significantly increases the production cycle, energy consumption and production cost of the curtain; the invention patent CN 105034533 A introduces a curtain and the production process of the curtain, and the adhesive fiber reinforced thermoplastic There is a PE film between the board and the non-woven fabric material, and the non-woven fabric and the board are quickly bonded by means of pressure holding with a hot plate and cooling with a cold plate, which shortens the production cycle of the curtain product to a certain extent, but the appearance of the product Poor, large fluctuations in thickness uniformity, PE film adhesive is used, because its melting point is 100-130 ° C, it is easy to penetrate into the felt under medium and high temperature conditions, and it is impossible to prepare thin fiber-reinforced sheets, and the hot plate holding process Limits the production speed of products

The above three patents are all covering curtains developed with fiber-reinforced panels and non-woven fabric adhesive materials as the core, and have not studied the formula of lightweight fiber-reinforced thermoplastic sheets for passenger car curtains for the characteristics of low VOC, low odor, and high strength.
