Abstract
Using polypropylene as mother material, adding polar monomer, cograft polar monomer and initiator in a certain proportion and through reacion for 1-3 min and at 170-220 deg. c and pelletizing in pelletizer, the modified polypropylene material is produced. The high-polarity polyproplene material of the present invention can raise polarity of product and improve surface decoration property of product, and it has excellent macheanical property the same as original polypropylene and no high requirement for production equipment.
Description
The present invention relates to a kind of method for preparing high-polarity modified polypropylene material, belong to technical field of polymer materials.
Present polypropylene material is a non-polar material, and is very poor with the sticking power of paint polar materials, therefore needs to improve polyacrylic polarity with certain methods.Method commonly used has the surface grafting method, surface-crosslinked method, surface coating modified method etc.These methods all have pair equipment requirements higher, the cost height, and shortcomings such as the low and contaminate environment of efficient to large-scale product, are difficult for again realizing as nerf bar etc.Therefore, need some industrial simple and feasible, can make polypropylene material itself have high polar method.
The purpose of present method is the modified polypropylene material of preparation a kind of high polarity and good mechanical performance, is masterbatch with the polypropylene, carries out cografting (polar monomer and cografting polar monomer) with two or more monomer and reaches the purpose of modification.
The present invention prepares the method for high-polarity modified polypropylene material, comprises following each step:
(1) with polypropylene, polar monomer, cografting polar monomer and initiator uniform mixing, its ratio (parts by weight) is:
Polypropylene 100
Polar monomer 2-10
Cografting polar monomer 1-8
Initiator 0.2-1.5
(2) said mixture was reacted 1-3 minute under 170 ℃-220 ℃ temperature, use the tablets press granulation, be high-polarity modified polypropylene material.
High-polarity modified polypropylene material of the present invention has following advantage:
1, the preparation method of modified polypropylene material of the present invention is low for equipment requirements, the efficient height.
2, the preparation method of modified polypropylene material of the present invention can prevent polyacrylic degraded in the course of processing, can keep the original excellent mechanical property of polypropylene.
3, modified polypropylene material of the present invention has high polarity.
4, modified polypropylene material of the present invention can be used as the polarity addition material, improves the polarity of goods, improves the surface daub on a wall of goods.
The masterbatch polypropylene that the present invention is used is commercial granulated material.
Typical polar monomer is for having hydroxyl, the esters of unsaturated carboxylic acids of epoxy group(ing) isopolarity gene, and such as Hydroxyethyl acrylate (HEA), hydroxyethyl methylacrylate (HEMA), glycidyl methacrylate (GMA), Rocryl 410 (HPMA).
Typical cografting polar monomer is vinylbenzene (St) and substituent thereof, as p-methylstyrene, and o-methyl styrene, 1-vinyl toluene.
The weight ratio of polar monomer and cografting polar monomer is 10: 1-0.5: 1.
Initiator is a thermolysis organic peroxy type initiator, as benzoyl peroxide, peroxidized t-butyl perbenzoate, dicumyl peroxide (DCP), and di-t-butyl peroxide or 2,5-dimethyl-2,5-two (5-butyl peroxy) acetylene-3.
Embodiments of the invention are example to produce 2kg modification polyene material:
Claim poly-2kg polypropylene, polar monomer 100g, cografting monomer 50g, initiator 12g mixes them, extruding pelletization in single screw extrusion machine (each section temperature is 170-220 ℃), in 2 minutes reaction times, screw speed is 40 rev/mins.Products obtained therefrom is high utmost point modified polypropene pellet.
| Polar monomer | The cografting polar monomer | Initiator | Melting index | Contact angle (degree) | The absorbancy ratio |
| ????(St) | ??(Dcp) | ??(g/10min) | |||
| GMA6 part GMA6 part GMA5 part GMA4 part GMA3 part HEMA4 part HEMA6 part | 6 parts 3 parts 2.5 parts 2 parts 3 parts 4 parts 6 parts | 0.3 0.6 part 0.6 part 0.9 part 0.6 part 0.6 part 0.6 part of part | ????1.0 ????4.6 ????5.7 ????8.5 ????3.1 ????2.1 ????1.5 | ????72 ????70 ????70 ????74 ????75 ????74 ????72 | ??0.410 ??0.507 ??0.655 ??0.217 ??0.192 ??0.210 ??0.370 |
Annotate: the absorbancy in the table is than the ratio (C=O/-CH that is meant carbonyl peak and the area at methyl peak in the infrared spectrum
3). what its reflected is the size of polyacrylic relative percentage of grafting.
