Abstract

The utility model relates to a kind of motorcoach composite material sound-absorption and heat-insulation trim board, and this trim board comprises abatvoix and sound-absorption and heat-insulation is cotton, and abatvoix and sound-absorption and heat-insulation cotton are linked together by glue-line.Described abatvoix adopts composite material to be that raw material adopts mould pressing process to be manufacture method, and the cotton raw material of described sound-absorption and heat-insulation is poly-ester fibres.This trim board has the effective feature of the low sound-absorption and heat-insulation of intensity high cost.

Description

Motorcoach composite material sound-absorption and heat-insulation trim board
Technical field
The utility model relates to a kind of motorcoach composite material sound-absorption and heat-insulation trim board, comprises composite material abatvoix and composite material sound-absorption and heat-insulation cotton.Specifically, the utility model relates to a kind of motorcoach composite material sound-absorption and heat-insulation trim board, and this trim board can be used for motorcoach interior trimming parts, has effect of sound-absorption and heat-insulation.This trim board comprises and adopts composite material to be that raw material adopts mould pressing process to be the abatvoix of manufacture method and adopts poly-ester fibres to be that the sound-absorption and heat-insulation of raw material is cotton, and described abatvoix and sound-absorption and heat-insulation cotton are linked together by glue-line.
Background technology
Along with the development of motorcoach manufacturing technology, require more and more higher to the traveling comfort of environment inside car.This traveling comfort requires to include low noise and suitable temperature.In order to meet this traveling comfort requirement, motorcoach maker can adopt abatvoix as vehicle roof inner decoration plate usually to reduce main cabin noise, re-lays sponge as thermal insulation layer to keep compartment temperature in abatvoix inside.And the raw material that this abatvoix adopts is aluminium-plastic panel.This method can solve sound-absorption and heat-insulation problem to a certain extent, and shortcoming is that aluminium-plastic panel intensity is low, often occurs breakage phenomenon when mounted, if increase aluminium-plastic panel thickness, then can bring the problem that cost is high.In addition, the sponge that abatvoix inside adopts is generally polyurethane sponge, and its sound-absorption and heat-insulation effectiveness comparison is poor.
For this reason, we need to develop a kind of novel passenger vehicle sound-absorption and heat-insulation trim board, under the prerequisite ensureing good decorative effect, have better sound-absorption and heat-insulation effect, can also ensure lower cost simultaneously.
Summary of the invention
The utility model relates to a kind of sound-absorbing heat-insulating decorative board of motorcoach, and this trim board comprises abatvoix and sound-absorption and heat-insulation is cotton, and abatvoix and sound-absorption and heat-insulation cotton are linked together by glue-line.Described abatvoix adopts composite material to be that raw material adopts mould pressing process to be manufacture method, and the cotton raw material of described sound-absorption and heat-insulation is poly-ester fibres.Described composite material comprises fiber-reinforced plastic, SMC, GMT or BMC; Described fiber comprises glass fibre, carbon fiber or basalt fibre; Described plastics comprise thermoplastic plastic or thermosetting plastic; Described thermosetting plastic comprises unsaturated polyester (UP) or epoxy resin; Described thermoplastic plastic comprises polypropylene or nylon.
This trim board has the effective feature of the low sound-absorption and heat-insulation of intensity high cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a composite material sound-absorption and heat-insulation trim board described in the utility model embodiment.
Detailed description of the invention
The detailed description of the invention of a kind of example meeting the utility model feature is described below in conjunction with accompanying drawing.
As shown in Figure 1, this example comprises abatvoix 101 and sound-absorption and heat-insulation cotton 102.The raw material of described abatvoix is SMC composite material, and thickness is 3 millimeter, and length is 2044 millimeters, and width is 1022 millimeters; The manufacture method of described abatvoix is mould pressing process.Described sound-absorption and heat-insulation cotton is that PP-PET bicomponent fibers is cotton, and every square meter weight is about 500 grams, and length is consistent with abatvoix with width.Described abatvoix and sound-absorption and heat-insulation cotton are linked together by glue-line.
Above detailed description of the invention just meets an example of feature of the present invention.Under the prerequisite without prejudice to the technology of the present invention feature, technical personnel can also formulate other embodiment under this instructions direct.
