Embodiment 1

[0017] Example 1, using the PP honeycomb panel as the skeleton layer 2, placing the PP honeycomb panel on the punching tool, and punching it according to the size required by the design with a four-column cutting machine; After the surface layer non-woven fabric 1 and the back layer non-woven fabric 3 of the hot-melt adhesive powder bonded to the PP honeycomb panel are hung separately, the punched PP honeycomb panel is placed in the groove of the lower heating plate, and heated at the heating temperature. Under the conditions of 180°C and a holding time of 50s, close the heating and bonding tool to complete the composite and crimp bonding of the three materials. At this time, the surface layer non-woven fabric 1 and the back layer non-woven fabric 3 are double crimping Composite bonding; the upper and lower heating plates here can be composed of N heating zones, and each heating zone is controlled by a separate temperature control system. Multi-zone heating is easy to control t...

Embodiment 2

[0018] Example 2 is the same as Example 1, the difference is that, when heating the composite pressing, the heating temperature is 130°C, and the holding time is 60s, and the heating and bonding tool is closed to complete the composite and pressing of the three materials. Edge bonding; when cooling and shaping, under the conditions of cooling temperature 15°C and pressure holding time 50s, close the tooling, and open the tooling to take out the product after the set time is reached.

Embodiment 3

[0019] Example 3 is the same as Example 1, the difference is that, when heating the composite pressing, the heating temperature is 230°C, and the holding time is 40s, and the heating and bonding tool is closed to complete the composite and pressing of the three materials. Edge bonding; when cooling and shaping, under the conditions of cooling temperature 25°C and pressure holding time 70s, close the tooling, and open the tooling to take out the product after the set time is reached.

[0020] The spare wheel cover of the suitcase prepared in the above embodiments has the characteristics of beautiful appearance, light weight, no smell, safety and environmental protection, sound insulation and noise reduction, etc., and is an ideal interior decoration product of the suitcase.

Abstract

The invention discloses a double-flanged PP honeycomb plate luggage case spare cover plate and its production method. The spare cover plate is formed through compounding and flanging bonding of a skeleton layer (2), and a surface layer nonwoven fabric (1) and a back layer nonwoven fabric (3) which are compounded to the surfaces of the skeleton layer, the surface layer nonwoven fabric (1) and the back layer nonwoven fabric (3) are bonded in a double flanging compounding manner, the skeleton layer (2) is a PP honeycomb plate, and the surface layer nonwoven fabric (1) and the back layer nonwoven fabric (3) are nonwoven fabrics compounded with hot melt adhesive powder which can be easily bonded with a PP material respectively; and the back layer nonwoven fabric (3) at the back of the skeleton layer (2) is provided with a shock pad (4). The production method sequentially comprises the following steps: skeleton layer punching, heating compounding flanging, cooling fixing, semi-finished product punching and finished product production. The nonwoven fabric is compounded with back layer of the PP honeycomb plate and is bonded with the surface layer nonwoven fabric in a double flanging manner, so the strength and the rigidity of the cover plate are increased, the weight of the cover plate and the whole car noises are reduced, and the requirements of the car industry on light weight, environmental protection and beauty are met.

Description

Technical field: [0001] The invention relates to the technical field of processing and production of vehicle interior products, in particular to a double-pressed PP honeycomb board luggage case spare tire cover and a production method thereof. Background technique: [0002] As we all know, the spare tire cover of the trunk is widely used in the field of automotive interiors, and is an important part of automotive interior products. It plays an important role in covering the spare tire, carrying heavy objects, and decorating the trunk. Existing trunk spare wheel cover, the skeleton has several kinds of wood fiber board, PP wood powder board, PHC honeycomb paper glued board, etc., the above several kinds of skeleton materials have the following deficiencies or defects, such as wood fiber board is heavy and easy to absorb moisture Moldy and deformed; PP wood powder board has a strong smell, low strength, poor rigidity, and VOC indicators are difficult to meet the requirements; ...
