Embodiment 1

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

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

[0020] (1) Placement of raw materials: stack the hemp fiberboard with glue film on the loading worktable, and transfer the hemp fiber to the drying oven net chain by the suction mechanism;

[0021] (2) Drying temperature softening: Put the hemp fiberboard on the oven mesh chain in a rotating mesh chain oven for drying temperature softening, the drying temperature softening temperature is 190 ℃, and the time is 100s; while the drying temperature is softened, the fabric is laid flat on Surface bonding on the feeding mechanism;

[0022] (3) Compression molding: Lay the material softened by baking temperature on the mold using a rotating mesh chain, and obtain a semi-fin...

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 roof tops, and belongs to the technical field of automobile interior parts manufacturing. Background technique [0002] The car roof is installed on the top of the car to play a role in decoration and energy absorption. In the low-carbon era where environmental protection, energy saving, and individualization are increasingly pursued, car interiors have become an important factor for people to buy cars. Therefore, more and more attention is paid to car interior parts. [0003] In the prior art, the formability, impact, environmental protection and other performance indicators 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 canopies mainly have the following problems: 1. It is not easy...
