Abstract
The present invention discloses PVB anti-impact modified resin MBS and a preparation method. The PVB anti-impact modified resin MBS is prepared from the following components by weight: 10-50 parts of methyl methacrylate, 10-50 parts of styrene, 0-10 parts of acrylate, 50-100 parts of styrene-butadiene latex, 0.5-1 part of potassium persulfate and 5-10 parts of a stabilizer. The impact strength, transparency, haze and color are improved, and performances are significantly improved.
Description
Technical field
the present invention relates to a kind of PVB Resin Used As Impact Modifier MBS and preparation method thereof, belong to additives for plastics production technical field.
Background technology
pVB Resin Used As Impact Modifier MBS both can while toughness reinforcing, keep the transparency of PVC to greatest extent, simultaneously compared with other impact modifier, in equal add-on situation, the toughness of goods can also be promoted by a larger margin, be thus widely used in the processed and applied process of the engineering plastics such as PVC and PBT/PC.But due to the component of existing PVB Resin Used As Impact Modifier MBS and preparation method more unreasonable, have impact on the performance of PVB Resin Used As Impact Modifier MBS.
Summary of the invention
the object of the invention is to, PVB Resin Used As Impact Modifier MBS and preparation method thereof is provided.Invention increases shock strength, transparency, mist degree, colourity, remarkable improve performance.
technical scheme of the present invention: a kind of PVB Resin Used As Impact Modifier MBS, is obtained by following component by weight: methymethacrylate 10-50 part, vinylbenzene 10-50 part, acrylate 0-10, styrene-butadiene latex 50-100 part, Potassium Persulphate 0.5-1 part and stablizer 5-10 part.
in above-mentioned PVB Resin Used As Impact Modifier MBS, obtained by following component by weight: methymethacrylate 25 parts, vinylbenzene 30 parts, acrylate 5 parts, styrene-butadiene latex 70 parts, Potassium Persulphate 0.7 part and stablizer 8 parts.
the preparation method of aforesaid PVB Resin Used As Impact Modifier MBS, described stablizer is dissolved in 50-100 vinylbenzene by 10-20 part hydrogen polysiloxanes, be stirred to and dissolve completely, add in the mixed solution of 1-5 part sodium lauryl sulphate and 500-1000 part deionized water composition again, stirred at ambient temperature pre-emulsification 15min, then fine crankshaft 5min, then after 60-85 degree Celsius, add Potassium Persulphate and carry out polyreaction 3h, obtain finished product.
the preparation method of aforesaid PVB Resin Used As Impact Modifier MBS, described stablizer is dissolved in 70 vinylbenzene by 15 parts of hydrogen polysiloxanes, be stirred to and dissolve completely, add in the mixed solution of 2 parts of sodium lauryl sulphate and 700 parts of deionized water compositions again, stirred at ambient temperature pre-emulsification 15min, then fine crankshaft 5min, then after 60-85 degree Celsius, add Potassium Persulphate and carry out polyreaction 3h, obtain finished product.
the preparation method of aforesaid PVB Resin Used As Impact Modifier MBS, polyreaction is carried out by after methymethacrylate, styrene-butadiene latex, vinylbenzene and crylic acid ester mixture, add Potassium Persulphate and stablizer while stirring in the polymerization, after reacting completely, carry out again condensing, dewater, dry, obtain finished product.
compared with prior art, present invention employs brand-new component and proportion relation, the combination of this component and proportion relation be applicant through repetition test, compare, screen, sum up and obtain, compared with existing MBS, shock strength of the present invention can improve more than 20%, transparency, mist degree, colourity three indexs all can improve more than 15%, remarkable improve performance.Further, applicant also improves stablizer, the maximum performance short slab of existing MBS is exactly stablizer, because the particle shape of existing stablizer is larger, and particle diameter comparatively unshapeliness, stablizer cannot be reacted with reactant effectively, thus reduce the performance of product, stablizer after improvement significantly can reduce particle shape, and improve the uniformity coefficient of particle diameter, the particle shape of the stablizer that applicant adopts instrument to detect as shown in Figure 1, and the particle shape of existing stablizer as shown in Figure 2, stabiliser particle after improving as seen from the figure is less, evenly, thus greatly improve the performance of product.
Accompanying drawing explanation
fig. 1 is the particle shape figure of stablizer of the present invention;
fig. 2 is the particle shape figure of existing stablizer.
