Description
Technical field
The present invention relates to rubber and plastic field, be specifically related to a kind of high intensity modified PBT rubber.
Background technology
Polybutylene terephthalate (PBT), is called for short PBT, belongs to polyester series, be by 1.4-pbt butanediol and terephthaldehyde
Acid or terephthalate polycondensation form, and the milky made via mixing program is translucent to opaque, crystal type
Thermoplastic polyester.Shortcoming is that notch impact strength is low, and molding shrinkage is big, and using effect is not good enough.
Summary of the invention
It is an object of the invention to provide one and have that intensity is high, hardness is big, excellent in cushion effect, molding shrinkage is little,
The high intensity modified PBT rubber of stay-in-grade feature.
The technical scheme is that, a kind of high intensity modified PBT rubber, by PBT resin, filler, toughener, nucleation
Agent, lubricant and dispersant composition, described filler is alumina powder, and described toughener is polyvinyl butyral resin, described
Nucleator is sodium succinate, and described lubricant is oleamide, and described dispersant is glycerol monostearate, and described high intensity is modified
Parts by weight shared by each composition of PBT rubber are respectively as follows: described PBT resin and account for 79-84 part, and described alumina powder accounts for 25-30 part, institute
Stating polyvinyl butyral resin and account for 13-17 part, described sodium succinate accounts for 18-23 part, and described oleamide accounts for 6-10 part, described stearic acid
Monoglyceride accounts for 4-8 part.
In a preferred embodiment of the present invention, parts by weight shared by the described high intensity each composition of modified PBT rubber are concrete
For: described PBT resin accounts for 80 parts, and described alumina powder accounts for 26 parts, and described polyvinyl butyral resin accounts for 14 parts, described sodium succinate
Accounting for 19 parts, described oleamide accounts for 7 parts, and described glycerol monostearate accounts for 5 parts.
In a preferred embodiment of the present invention, parts by weight shared by the described high intensity each composition of modified PBT rubber are concrete
For: described PBT resin accounts for 83 parts, and described alumina powder accounts for 29 parts, and described polyvinyl butyral resin accounts for 16 parts, described sodium succinate
Accounting for 22 parts, described oleamide accounts for 9 parts, and described glycerol monostearate accounts for 7 parts.
Of the present invention is a kind of high intensity modified PBT rubber, and this product has that intensity is high, hardness is big, impact strength
High, molding shrinkage feature little, stay-in-grade.
Detailed description of the invention
Below presently preferred embodiments of the present invention is described in detail so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that thus protection scope of the present invention is made apparent clear and definite defining.
Of the present invention is a kind of high intensity modified PBT rubber, by PBT resin, filler, toughener, nucleator, lubrication
Agent and dispersant composition, described filler is alumina powder, and described toughener is polyvinyl butyral resin, and described nucleator is

Parts by weight shared by each composition are respectively as follows: described PBT resin and account for 79-84 part, and described alumina powder accounts for 25-30 part, described poly-second
Enol butyral accounts for 13-17 part, and described sodium succinate accounts for 18-23 part, and described oleamide accounts for 6-10 part, described stearic acid list glycerol
Ester accounts for 4-8 part.
Further, parts by weight shared by the described high intensity each composition of modified PBT rubber are particularly as follows: described PBT resin accounts for
80 parts, described alumina powder accounts for 26 parts, and described polyvinyl butyral resin accounts for 14 parts, and described sodium succinate accounts for 19 parts, described oleoyl
Amine accounts for 7 parts, and described glycerol monostearate accounts for 5 parts.
Further, parts by weight shared by the described high intensity each composition of modified PBT rubber are particularly as follows: described PBT resin accounts for
83 parts, described alumina powder accounts for 29 parts, and described polyvinyl butyral resin accounts for 16 parts, and described sodium succinate accounts for 22 parts, described oleoyl
Amine accounts for 9 parts, and described glycerol monostearate accounts for 7 parts.
Proportioning is carried out so that the properties of product height obtained differs by each composition Different Weight number.
Of the present invention is a kind of high intensity modified PBT rubber, and this product has that intensity is high, hardness is big, impact strength
High, molding shrinkage feature little, stay-in-grade.
The foregoing is only the detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, any
Those of ordinary skill in the art in the technical scope that disclosed herein, the change that can expect without creative work or
Replace, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be limited with claims
Fixed protection domain is as the criterion.
