Embodiment Construction
[0034] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0035] Such as image 3 As shown, a one-time forming compartment panel for a van includes a surface adhesive 11 , a first composite felt 12 , a second composite felt 13 , a PVC foam board 14 , and a flow-guiding composite felt 15 . The surface adhesive 11, the first composite felt 12, the second composite felt 13, the PVC foam board 14, and the diversion composite felt 15 are laid sequentially. The first composite felt 12 is an ordinary composite felt. The second composite felt 13 is a composite felt with flow guiding function. Further preferably, the thickness of the PVC foam board is 5-45 mm, and the present invention uses a PVC foam board with a thickness of 25 mm. Further preferably, the thickness of the compartment panel is 10-50 mm, and the present invention adopts a compartment panel with a thickness of 40 mm.

Abstract
The invention relates to an integrally formed carriage plate for a van and a manufacturing technology. The outer layer of the carriage plate is made of glass steel, and a PVC foam plate is adopted as an interlayer. The technology comprises the following steps that 1, demoulding material processing and room-temperature curing are performed; 2, a surfacing mat, a composite mat, the PVC foam plate and a diversion composite mat are laid; 3, omega tubes and a winding pipe are fixed, sealing adhesive tapes are bonded, and a demoulding cloth and a vacuum bag are laid to form a vacuum system; 4, the vacuum system is connected with a resin collector in a sealed mode, and the leakproofness of the vacuum system is detected; 5, vacuum pressure maintaining is performed; 6, resin is prepared and poured in a vacuum mode; 7, solidifying, demoulding and postprocessing are performed. Compared with prior art, the PVC foam plate is used as the interlayer, and therefore the advantages of being capable of achieving water resistance, flame retardance, acid and alkali resistance, moth proofing, light mass, high hardness, heat preservation, sound insulation and shock absorption; vacuum infusion and integrally forming are achieved, and therefore the two surfaces of the carriage plate are smooth.
Description
technical field [0001] The invention relates to a compartment panel, in particular to a once-formed compartment panel for van trucks and a manufacturing process. Background technique [0002] A van is a type of compartment with an independent closed structure, or an integral closed structure compartment integrated with the driver's cab, and is mainly used for commercial vehicles carrying goods. The compartment board of the van can be made of iron corrugated, color steel plate, aluminum flat plate, aluminum alloy corrugated or foamed insulation compartment material. [0003] Compared with the car body with metal skeleton structure, the glass fiber reinforced composite material car plate has the advantages of good manufacturability, low cost and light weight of the whole vehicle because it has no skeleton and no pre-embedding in the process of manufacturing. Although the honeycomb sandwich panel has the characteristics of light weight, it is expensive. Through various compar...
