Description

Compression-resistant composite board with good ventilation performance

Technical Field

The utility model relates to a resistance to compression composite sheet field, concretely relates to resistance to compression composite sheet with good ventilation performance.

Background

The composite board is a board type formed by combining two or more than two materials, and the board is mostly made of inorganic materials in a compounding way and has high hardness.

The existing compression-resistant composite board is found to have the following defects in the manufacturing and using processes: since the composite panel is hard, the ventilation ability is weak, and the sound is propagated faster in a solid than in air, resulting in easy propagation of noise by the composite panel.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above defect, provide the resistance to compression composite sheet that has good ventilation performance.

The utility model aims at realizing through the following mode:

resistance to compression composite sheet with good ventilation performance, including the core, the upper and lower two sides of core all is glued in proper order has sound-proof course, waterproof layer, ventilation layer, protective layer and is used for the back up coat of resistance to compression, and the length and the width homogeneous phase of core, sound-proof course, waterproof layer, ventilation layer, protective layer and back up coat are the same, and the middle part of core is equipped with a plurality of sound holes that separate with the sound-proof cooperation of sound-proof course, and the one side that the core was kept away from to the back up coat is equipped with a plurality of ventilation grooves.

Further, the protective layer is the lattice structure that can make puigging, waterproof layer and ventilation layer closely laminate, through setting up lattice structure, has increased sticky area to sticky fixity and composite sheet's stability have been improved.

Further, the lateral surface of core, puigging, waterproof layer, ventilation layer, protective layer and back up coat all is glued there is the parcel area that is used for preventing that core, puigging, waterproof layer, ventilation layer and protective layer from the back up coat and drops to improve the connectivity of resistance to compression composite sheet, avoid droing between the composite sheet layer.

Further, the ventilation groove is the rectangle, through the ventilation groove that runs through composite sheet surface, the air permeability of improvement composite sheet that can be fine improves the performance of composite sheet, and sound cotton is inhaled to downthehole being equipped with of sound insulation, separates the sound hole and be circular, can also effectively improve the sound insulation of composite sheet.

The utility model discloses produced beneficial effect does: the upper and lower two sides of core all are glued in proper order and have the puigging, the waterproof layer, the ventilation layer, the back up coat of protective layer and being used for the resistance to compression, the middle part of core be equipped with the puigging cooperation syllable-dividing sound hole a plurality of, still be equipped with the soundproof cotton of further reinforceing syllable-dividing effect in the soundproof hole, the one side that the core was kept away from to the back up coat is equipped with a plurality of ventilation slots, can effectively improve the compressive property and the ventilation performance of composite sheet, the setting of protective layer makes the composite sheet be difficult for droing, the security that has improved the user of service when having improved the composite sheet quality.
