Embodiment 1

[0018] Hemp fiber car roof, its specification is: L1200×W1000mm. The weight of hemp fiberboard is 1200g / m 2 , the thickness is 5mm; the adhesive film is PA mesh film; the fabric is a composite fabric of knitted fabric and non-woven fabric.

[0019] A kind of production method of hemp fiber car headliner, the steps are as follows:

[0020] (1) Laying of raw materials: Stack the hemp fiber boards with adhesive film on the loading table, and the hemp fiber is transferred to the oven mesh chain by the suction mechanism;

[0021] (2) Baking and softening: put the hemp fiber board on the oven net chain in a rotating net chain oven for drying and softening. The softening temperature is 190°C and the time is 100s; Surface bonding on the feeding mechanism;

[0022] (3) Compression molding: use a rotating network chain to spread the softened material on the mold, and obtain a semi-finished product after holding the pressure; the holding pressure is 100bar, and the holding time is 60...

Abstract

The invention relates to a production method of fibrilia automobile upholstery, and in particular relates to a production method of a fibrilia automobile ceiling, belonging to the technical field of manufacture of automobile upholstery. The production method comprises the following steps of: carrying out drying and heating treatment on a film-attached fibrilia board; then, conveying the film-attached fibrilia board to the center of an upper die and a lower die through a chain; carrying out cold press molding on the put fabric by using a product die; coldly standing for a period of time after molding; and finally, cutting by using a water jet cutter to obtain the ceiling, then, checking, casing and storing. By using the production method, the problems of difficulty in molding, complex process, low toughness, no environment friendliness and the like of the automobile ceiling are solved; the produced product is unique in machining process, low in energy source loss, light in weight, low in water content, high in bending strength, high in modulus, resistant to high temperature, low temperature, impact and wrinkles, strong in rigidity, free of acute-angle sections generated after the automobile ceiling is crushed as well as safer and more reliable; and materials belong to regenerative resources, and discarded products can be recycled and are also easy to realize natural degradation, and therefore, remarkable environment-friendly performance is achieved, and the production method accords with the low-carbon trend.

Description

technical field [0001] The invention relates to a production method of hemp fiber automobile interior parts, in particular to a production method of hemp fiber automobile headliner, and belongs to the technical field of automobile interior decoration parts manufacturing. Background technique [0002] The car roof is installed on the top of the car to play the role of decoration and energy absorption. In the low-carbon era that is more and more pursuing environmental protection, energy saving, and individualization, the interior of a car has become an important factor for people to choose a car, so people pay more and more attention to interior parts of cars. [0003] In the existing technology, performance indicators such as formability, impact resistance, and environmental protection of the roof (chemical synthetic materials, such as PP glass fiber, PU glass fiber, etc.) have become bottlenecks, restricting the development of the car roof. [0004] The existing canopy main...
