Abstract
The invention discloses an improved surface hardness PMMA/ABS alloy, which comprises the following parts: 77.6% PMMA, 19.4% ABS and 3% compatible agent. The invention modifies present uneven blending phenomenon, which makes PMMA/ABS alloy application more widely.
Description
Technical field
The present invention relates to a kind of engineering plastics, particularly a kind of PMMA/ABS alloy that improves surface hardness.
Background technology
The method for preparing at present the PMMA/ABS alloy mainly is that PMMA, ABS are carried out blend with twin screw extruder.Therefore gained plastic cement alloy surface hardness is not high and surperficial inhomogeneous, and generally the hardness of HB all can't reach, and defines the scope of its use yet, so it is necessary that this alloy is carried out the raising of surface hardness.
Below be that the test that PMMA and the direct co-blended of ABS are drawn a design is improved:
| ABS hardness test result | |||
| Carrying capacity: 4.9N | |||
| Testing time | 10 | ?6 | ?6 |
| Hardness | HB | ?H | ?2H |
| The result | NG | ?NG | ?NG |
With ABS+PMMA (by taking out grain at 4: 1), the hardness test result is as follows:
| ABS+PMMA hardness test result | |||
| Carrying capacity: 4.9N | |||
| Testing time | 8 | ?4 | ?4 |
| Hardness | HB | ?H | ?2H |
| The result | NG | ?NG | ?NG |
Above-mentioned prior art produces trouble and inconvenience in use, remains in fact to be improved.
Summary of the invention
The object of the invention provides a kind of PMMA/ABS alloy that improves surface hardness.
A kind of PMMA/ABS alloy that improves surface hardness, wherein, by weight, PMMA77.6 part, 19.4 parts in ABS material, 3 parts in compatilizer material.
A kind of PMMA/ABS alloy that improves surface hardness, wherein, described compatilizer is MBS.
The present invention adopts the method for adding compatilizer in the co-blended process, the PMMA/ABS alloy is carried out surface hardness to be improved, PMMA/ABS alloy surface hardness can be improved to some extent, and improved the uneven phenomenon of original blend, the service requirements that material can be reached, the official that the PMMA/ABS alloy is used adds extensively.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing:
A kind of PMMA/ABS alloy that improves surface hardness, wherein, by weight, PMMA77.6 part, 19.4 parts in ABS material, compatilizer material MBS3 part.
The PMMA plastics have good optical characteristics and gasproof marquis variation characteristic.The penetrance of white light is up to 92%.The PMMA goods have very low double refraction.PMMA has the room temperature creep properties.Along with load strengthens, the time growth, can cause the stress cracking phenomenon.PMMA has shock resistance characteristic preferably.
The terpolymer that ABS plastic is made up of vinyl cyanide, divinyl, vinylbenzene.It has the machinability of styrenic thermoplastic plastics, the rubber toughness of divinyl, the chemical resistance of vinyl cyanide.
Have advantages such as shock-resistant, high gloss, fast light, the easy demoulding, easy dyeing in conjunction with the PMMA/ABS alloy of above two kinds of plastics.
MBS (Methyl methacrylate-Butadiene-Styrene) resin is methylacrylic acid methyl esters (M), the terpolymer of divinyl (B) and vinylbenzene (S), and it has typical nucleocapsid structure.Because its solubility parameters (XX) is close with PVC (XX), so both thermodynamic compatibilities are good, show as PVC and have very high resistance to impact shock under room temperature or low temperature.
Hardness test by the product of invention output is as follows:
| Carrying capacity: 4.9N | ||||
| Project | Before the modification | After the modification | ||
| Hardness test number of times (9 times) | HB | ?NG | ?HB | ?OK |
The above; only be the preferable feasible embodiment of the present invention; can not therefore promptly limit to interest field of the present invention; concerning being familiar with those of ordinary skill in the art; such as use technical scheme of the present invention and technical conceive to make other various corresponding changes and distortion, and all these changes and distortion all should belong within the protection domain of claim of the present invention.
Claims (2)
1, a kind of PMMA/ABS alloy that improves surface hardness is characterized in that, by weight, and PMMA77.6 part, 19.4 parts in ABS material, 3 parts in compatilizer material.
2, a kind of PMMA/ABS alloy that improves surface hardness according to claim 1 is characterized in that described compatilizer is MBS.
