Abstract
The invention discloses a formula of foam reinforced polypropylene, which comprises polypropylene, assistants, a toughener, a foaming agent and a plasticizer, wherein the assistants are glass fibers and calcium carbonate, the toughener is acrylate copolymer, the foaming agent is ammonium bicarbonate, and the plasticizer is phenyl alkyl sulfate. According to the formula of foam reinforced polypropylene, the foam reinforced polypropylene has the advantages of high softness, heat insulation, favorable toughness, good plasticity and the like.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of formula of the Reinforced Polypropylene that foams.
Background technology
In recent years, along with the raising of PP Production Technology, the improvement of polymerization technique, the high-flowability polypropylene product development and application obtain remarkable progress; The foaming Reinforced Polypropylene has the advantages such as good processing characteristics, mechanical property, flame retardant properties and resistance toheat, has been widely used as outer casing member, connector and insulating mat spacing body etc. in electric equipment products.Polypropylene injection molding product is used widely in fields such as packing, transportation, household electrical appliances, automobile, offices.
Polypropylene product is divided into homopolymerization type and copoly type, and copoly type is divided into again block copolymerization type and random copolymerization.When the high workability homo-polypropylene was subjected to low-temperature impact, poor toughness, molding shrinkage were large, the easy buckling deformation of product, but its good fluidity, and tensile strength, flexural strength are high; High Flowability Polypropylene Copolymers has improved low-temperature impact, has snappiness preferably, has higher flow rate and the physicals of applauding, and makes the design of baroque large thin-wall injection-molded item become feasible; And can shorten the process-cycle in process of production, reduce processing temperature, injection pressure and energy consumption; Having processing can be good, punch die easily reaches the advantages such as the product buckling deformation is few; Comparatively speaking, the mobility of Co-polypropylene is slightly poorer than homo-polypropylene, and tensile strength, flexural strength are high not as the high workability homo-polypropylene.
The foaming Reinforced Polypropylene that provides on market in use has a lot of aspects not fully up to expectations, as aspects such as plasticity, toughness, the phenomenons such as product fracture in use often occur in enterprise, and therefore, a kind of well behaved foaming Reinforced Polypropylene will be the problem that current continuation solves.
Summary of the invention
The object of the present invention is to provide the formula of the good foaming Reinforced Polypropylene of a kind of softness, heat insulation, good toughness, plasticity.
Technical scheme of the present invention is that a kind of formula of the Reinforced Polypropylene that foams comprises polypropylene, auxiliary agent, toughner, whipping agent and softening agent, described auxiliary agent is glass fibre, calcium carbonate, toughner is acrylate copolymer, and whipping agent is bicarbonate of ammonia, and softening agent is the alkylsurfuric acid phenyl ester.
In a preferred embodiment of the present invention, each composition weight percent of the formula of described foaming Reinforced Polypropylene is that polypropylene accounts for 60%-70%, glass fibre accounts for 20%-25%, calcium carbonate accounts for 2%-5%, acrylate copolymer accounts for 3%-4%, bicarbonate of ammonia accounts for 0.5%-1%, and the alkylsurfuric acid phenyl ester accounts for 4.5%-5%.
In a preferred embodiment of the present invention, each composition proportion of the formula of described foaming Reinforced Polypropylene is that polypropylene accounts for 67%, and glass fibre accounts for 21%, and calcium carbonate accounts for 3%, and acrylate copolymer accounts for 3.4%, and bicarbonate of ammonia accounts for 0.7%, and the alkylsurfuric acid phenyl ester accounts for 4.9%.
Of the present inventionly be a kind of formula of the Reinforced Polypropylene that foams, make the foaming Reinforced Polypropylene that makes have the effects such as softness, heat insulation, good toughness, plasticity be good.
Embodiment
The below is described in detail preferred embodiment of the present invention, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
Of the present invention for a kind of formula of the Reinforced Polypropylene that foams, comprise polypropylene, auxiliary agent, toughner, whipping agent and softening agent, described auxiliary agent is glass fibre, calcium carbonate, and toughner is acrylate copolymer, whipping agent is bicarbonate of ammonia, and softening agent is the alkylsurfuric acid phenyl ester.
Further, each composition weight percent of the formula of described foaming Reinforced Polypropylene is that polypropylene accounts for 60%-70%, and glass fibre accounts for 20%-25%, calcium carbonate accounts for 2%-5%, acrylate copolymer accounts for 3%-4%, and bicarbonate of ammonia accounts for 0.5%-1%, and the alkylsurfuric acid phenyl ester accounts for 4.5%-5%.
Further, each composition proportion of the formula of described foaming Reinforced Polypropylene is that polypropylene accounts for 67%, and glass fibre accounts for 21%, and calcium carbonate accounts for 3%, and acrylate copolymer accounts for 3.4%, and bicarbonate of ammonia accounts for 0.7%, and the alkylsurfuric acid phenyl ester accounts for 4.9%.
Wherein, the physicals of this foaming Reinforced Polypropylene is by following testing method and test condition: in room temperature placement 24 hours, 23 ℃ of probe temperatures, 50 ℃ of relative humidity.Table specific as follows:
| Test event | Unit | Testing method | Measured data |
| Solubility exponent | g/10min | D1238 | 2.8 |
| Density | g/cm3 | D792 | 1.159 |
| Notched Izod impact strength | J/M | D256 | 83 |
| Bending strength | mpa | D790 | 35.57 |
| Modulus in flexure | mpa | D790 | 3428 |
| Tensile strength | mpa | D638 | 28 |
Can debug according to different ratios according to different demands, thereby reach different results of use.This product is applicable to the fixture on electric wire.
Of the present inventionly be a kind of formula of the Reinforced Polypropylene that foams, make the foaming Reinforced Polypropylene that makes have the effects such as softness, heat insulation, good toughness, plasticity be good.
The above is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work are within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
