Abstract
The embodiment of the utility model provides a composite board compares with single PMMA board and has anti bending strength and anti impact characteristic. The embodiment of the utility model provides a well composite board is specifically formed by three -layer composite, and top -down is a PMMA layer, ABS layer and the 2nd PMMA layer respectively, and wherein, a PMMA layer, ABS layer and the 2nd PMMA layer by heating, extrusion technology complex become. The english full name acrylonitrile butadiene styrene copolymers of ABS is that type polymer material structure is moulded to an intensity height, toughness heat good, easy machine -shaping, consequently packs composite board that the ABS layer obtained and have anti bending strength and the characteristic such as shock resistance between a PMMA layer and the 2nd PMMA layer.
Description
Technical field
The utility model embodiment relates to technical field of board processing, particularly relates to a kind of composite plate.
Background technology
At present, the material mainly acrylic board (PMMA, AcrylonitrilebutadieneStyrenecopolymers) that bathtub is conventional, acrylic board has highly polished, the advantage such as ageing-resistant, but its impact strength is poor, the shortcoming such as crisp, the easy to crack and flexural strength of property is poor.When making bathtub with its, for preventing it to be hit cracking, after its forming, all to apply the intensity of layer of glass for increasing it at its back side, preventing collision from ftractureing.But need to use a large amount of toxic chemical substances (as: cobalt water, acetone, MEK etc.) when applying glass fibre.These materials not only can work the mischief to human body, also pollute the environment, and increase the labour intensity of workman, increase product cost.
Utility model content
The utility model provides a kind of composite plate, has the characteristic such as flexural strength and shock resistance compared with single PMMA plate.
A kind of composite plate that the utility model provides, specifically comprise: it is composited by three layers, be respectively a PMMA layer, abs layer and the 2nd PMMA layer from top to bottom, wherein, a PMMA layer, abs layer and the 2nd PMMA layer are shaping by process combining such as heating, extruding.
Optionally,
One PMMA layer thickness is 0.4-0.5mm.
Optionally,
2nd PMMA layer thickness is 0.4-0.5mm.
Optionally,
This composite plate hot strength is not less than 42Mpa.
Optionally,
This composite plate impact strength is not less than 32Kj/ ㎡.
Optionally,
This composite plate bending strength is not less than 70Mpa.
The beneficial effect of the utility model embodiment is:
Compared with single PMMA plate, composite plate in the utility model embodiment, is specifically composited by three layers, is respectively a PMMA layer, abs layer and the 2nd PMMA layer from top to bottom, wherein, a PMMA layer, abs layer are become by process combining such as heating, extruding with the 2nd PMMA layer.The English full name AcrylonitrilebutadieneStyrenecopolymers of ABS, be that a kind of intensity is high, good toughness, be easy to thermoplastics type's Polymer Materials ' Structure of machine-shaping, between a PMMA layer and the 2nd PMMA layer, therefore fill the composite plate that abs layer obtains there is the characteristic such as flexural strength and shock resistance.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.

Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
The utility model provides a kind of composite plate, has the characteristic such as flexural strength and shock resistance compared with single PMMA plate.
Refer to Fig. 1 and Fig. 2, a kind of composite plate embodiment that the utility model provides, specifically comprise: it is composited by three layers, be respectively a PMMA layer 1, abs layer 2 and the 2nd PMMA layer 3 from top to bottom, wherein, a PMMA layer 1, abs layer 2 and the 2nd PMMA layer 3 are shaping by process combining such as heating, extruding.
Compared with single PMMA plate, composite plate in the utility model embodiment, is specifically composited by three layers, is respectively a PMMA layer, abs layer and the 2nd PMMA layer from top to bottom, wherein, a PMMA layer, abs layer are become by process combining such as heating, extruding with the 2nd PMMA layer.The English full name AcrylonitrilebutadieneStyrenecopolymers of ABS, be that a kind of intensity is high, good toughness, be easy to thermoplastics type's Polymer Materials ' Structure of machine-shaping, between a PMMA layer and the 2nd PMMA layer, therefore fill the composite plate that abs layer obtains there is the characteristic such as flexural strength and shock resistance.
It should be noted that, this composite plate is based on abs layer, and wherein a PMMA layer 2 and/or the 2nd PMMA layer 3 thickness are 0.4-0.5mm.
Refer to table 1 and table 2, through test, the composite plate embodiment in the utility model has the characteristics such as stronger flexural strength and shock resistance compared with single PMMA plate, wherein:
This composite plate hot strength is not less than 42Mpa;
This composite plate impact strength is not less than 32Kj/ ㎡;
This composite plate bending strength is not less than 70Mpa.
