Material.Polypropylene is mainly used in the fields such as automobile, household electrical appliances, tubing, medical treatment, food.Due to polypropylene material low-temperature flexibility relatively
Difference, if being accomplished by it is carried out the toughening modifying low-temperature flexibility with raising polypropylene material for low temperature environment, common changes
The material of kind polypropylene low temperature toughness is ethylene propylene diene rubber (EPDM), based elastomers (POE), styrene-butadiene-benzene
Ethylene elastomer (SBS), SEBS elastomer (SEBS), its consumption is generally polypropylene quality
10wt%~40wt%.As: Chinese patent CN 1221607C utilizes SEBS tenacity-increased profax；Chinese patent CN 102311584 B,
CN 102675745 A, CN 102516663 A be all to utilize POE tenacity-increased profax；Chinese patent CN 1119374 C utilizes
EPDM and SBS tenacity-increased profax.
Summary of the invention
The present invention provides a kind of cold-resistant toughened polypropylene material, has significantly effect to polyacrylic low-temperature flexibility conservation rate
Really.
Technical scheme is as follows:
A kind of cold-resistant toughened polypropylene material, it is made up of by weight percentage following component:

The steady agent of light 0.1 ~ 0.3 part.
Scheme further, described modified acicular wollastonite is to be carried out surface process by acicular wollastonite through titanate coupling agent
Rear draw ratio is 7:1 ~ 22:1, particle diameter is 600 ~ 1250 mesh.
Scheme further, described titanate coupling agent is isopropyl three (dioctylphyrophosphoric acid acyloxy) titanate esters.
Scheme further, described antioxidant is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propanoic acid] pentaerythritol ester
Compound with three [2,4-di-tert-butyl-phenyl] phosphite ester.
Described lubricant is ethylene bis stearamide.
The steady agent of described light is 50% hindered amine as light stabilizer 2,2,6,6-tetramethyl-4-piperidine alcohols stearate oligomerisation of propene
Mixture and 2-(2-hydroxyl-5-uncle good fortune base phenyl) compound of benzotriazole.
Scheme further, described cold-resistant toughened dose is hydrogenated polystyrene butadiene styrene triblock copolymer.
Usefulness of the present invention:
1, acicular wollastonite and two (to ethyl two benzal) sorbitol are used, especially by the present invention simultaneously as Polypropylene cold-resistant agent
It is that the holding to HOPP low-temperature flexibility has significant effect.
2, using compounding to acicular wollastonite and traditional polypropylene toughening agent, it keeps effect to polypropylene low temperature toughness
Than both individually using effect good.
3, acicular wollastonite and two (to ethyl two benzal) sorbitol usage amount of the present invention are the least, and typically its consumption is
0.5 ~ the 1.5wt% and 0.3 ~ 1% of polypropylene quality, has broken traditional acicular wollastonite and has used as reclaimed polypropylene charge and use
The amount that amount is also used for inserts use is much smaller, reduces cost and uses.
4, widen acicular wollastonite and the range of two (to ethyl two benzal) sorbitol, break conventional needle-like silicon
Lime stone is filled mainly as polyacrylic enhancing, and dibenzal sorbitol uses mainly as polyacrylic nucleator.
Detailed description of the invention
Below in conjunction with some embodiments, the invention will be further described with comparative example.
Note: following Izod notched impact strength performs GB/T 1843.
Low-temperature flexibility conservation rate=(impact strengths of impact strength/23 DEG C of-30 DEG C) * 100%.
The modification of acicular wollastonite is to add to account for gross mass 1% titanate coupling agent (NDZ-201) and enter in acicular wollastonite
Row surface processes gained.I.e. processed gained by the acicular wollastonite of 1% coupling agent NDZ-201 and 99%.Concrete processing mode is as follows:
First weigh the acicular wollastonite of 99 mass parts in high-speed mixer, then weigh the coupling agent NDZ-201 of 1 mass parts from a high speed
The upper end aperture of mixer is slowly added to and starts mixer carry out mixing to obtain modified acicular wollastonite.
The steady agent of light is 50% hindered amine as light stabilizer 2,2,6,6-tetramethyl-4-piperidine alcohols stearate oligomerisation of propene mixing
Thing and 2-(2-hydroxyl-5-uncle good fortune base phenyl) compound of benzotriazole.
Cold-resistant toughened dose is hydrogenated polystyrene butadiene styrene triblock copolymer.
