Abstract

The invention discloses yellowing-resistant PP (Polypropylene)/HDPE (High Density Polyethylene) plastic for an automotive interior part and a preparation method. The yellowing-resistant PP/HDPE plastic for the automotive interior part comprises, by weight part, 100 parts of polypropylene, 20 to 30 parts of high density polyethylene, 10 to 20 parts of ethylene-propylene-diene monomer, 1 to 3 parts of 3-aminopropyl triethoxysilane and 0.5 to 1.5 parts of yellowing-resistant agent. The preparation method comprises weighing up raw materials according to a ratio and melting and mixing, squeezing and prilling after uniform mixing. The yellowing-resistant PP/HDPE plastic for the automotive interior part is good in yellowing-resistant performance and easily machined to various automotive interior parts through the injection molding technology.

Description

The PP/HDPE of resistance to xanthochromia plastics and preparation method for automotive upholstery
Technical field
The present invention relates to a kind of plastic material and preparation method, relate in particular to the PP/HDPE of resistance to xanthochromia plastics and preparation method for a kind of automotive upholstery.
Background technology
Polypropylene, english abbreviation is PP, is nineteen fifty-seven first to drop into industrial production in Italy, is another the important plastics variety after polyethylene (PE).It has good thermotolerance, can be not destroyed at 135 ℃ of boiling 1000h yet, and the specific heat capacity of PP, thermal conductivity are all less than PE, but heat insulating ability is better than PE.PP belongs to non-polar polymer, has excellent dielectricity and electrical insulating property, and electrical property is not subject to the impact of ambient moisture and electric field frequency substantially, and in the working range allowing, temperature rising can make electrical property reduce, and its arc resistance is higher.
High density polyethylene(HDPE) (High Density Polyethylene, referred to as " HDPE ") is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.The milky appearance of ortho states HDPE, is to a certain degree translucent in meagre cross section.
PP/HDPE plastics, have good thermotolerance and winter hardiness, and chemical stability is good, but yellowing resistance is not good.
Summary of the invention
The PP/HDPE of resistance to xanthochromia plastics for automotive upholstery, comprise the component of following weight parts: 100 parts of polypropylene, high density polyethylene(HDPE) 20-30 part, terpolymer EP rubber 10-20 part, 3-aminopropyl triethoxysilane 1-3 part, resistance to xanthochromia agent 0.5-1.5 part.
Preferably,
Described resistance to xanthochromia agent is a kind of or its mixture in two (18) alcohol esters of thio-2 acid, hexamethyl phosphoric triamide, N-(ethoxy carbonyl phenyl)-N '-methyl-N '-phenyl formamidine and titanium dioxide.
Optimally,
Described resistance to xanthochromia agent is comprised of the component of following weight parts: described resistance to xanthochromia agent is comprised of the component of following weight parts: two (18) the alcohol ester 20-30 parts of thio-2 acid, hexamethyl phosphoric triamide 20-30 part, N-(ethoxy carbonyl phenyl)-N '-methyl-N '-phenyl formamidine 20-30 part, titanium dioxide 20-30 part.
Two (18) alcohol esters of thio-2 acid, No. CAS: 693-36-7.Hexamethyl phosphoric triamide, English name: hexamethyl phosphoric triamide, is abbreviated as HPT.N-(ethoxy carbonyl phenyl)-N'-methyl-N'-phenyl formamidine, No. CAS: 57834-33-0.Titanium dioxide, No. CAS: 13463-67-7.
Further, the present invention also provides the preparation method of a kind of automotive upholstery with the PP/HDPE of resistance to xanthochromia plastics: by proportioning, take each raw material, and after mixing, melting mixing, extruding pelletization.
The PP/HDPE of resistance to xanthochromia plastics for automotive upholstery of the present invention, have good anti-yellowing property, can be processed into easily by Shooting Technique the automotive upholstery of different shape.
Embodiment
Below in conjunction with embodiment, the invention will be further described.Polypropylene is the T30S that Period In Maoming petro-chemical corporation produces, and melt flow rate (MFR) MFR is 2.0g/10min; High density polyethylene(HDPE) is selected the HDPE resin of the Taiwan plastic cement company trade mark 9001; Terpolymer EP rubber is selected the EPDM resin that the Mitsui company trade mark is 4095.
Embodiment 1-5
According to corresponding embodiment 1-5 data in table 1, take after each raw material respectively, add in mixing tank and stir, control rotating speed in 350r/min, 80 ℃ of whipping temps, churning time 3 minutes, again through screw extrusion press extruding pelletization, 200 ℃ of extrusion temperatures, cooling forming in the cold water of 15 ℃, obtains the PP/HDPE of resistance to xanthochromia plastics for described automotive upholstery.
Table 1: automotive upholstery is with the PP/HDPE of resistance to xanthochromia plastic formula list position: kilogram
Test case
PP/HDPE plastics yellowing resistance to embodiment 1-5 is tested, and the PP/HDPE plastics of embodiment 1-5 is put into respectively to vulcanizer and be pressed into the sheet that thickness is 1mm, then pass through coldmoulding, cuts into the sample strip of 2cm * 5cm.Press GB/T16422.2-1999 plastics laboratory light source exposure test method, being placed in xenon lamp tans by the sun the proofing box of light xanthochromia and irradiates 1000 hours, then press GB2409-80 plastics yellowness index test method, survey its yellowness index, obtain its xanthochromia index △ YI as shown in table 2 below.
