Abstract
The invention relates to an inner padding for a TPE (thermoplastic elastomer) bottle cap applicable to dairy products. The inner padding mainly comprises the components in parts by weight: 30-35 parts of SEBS (Styrene-Ethylene/Butylenes-Styrene)-1, 15-18 parts of SEBS-2, 6-9 parts of SEBS-3, 3-5 parts of mineral oil, 18-22 parts of polypropylene, 10-15 parts of ethylene-propylene copolymer, and 0.5-1 part of additives. The inner padding is manufactured by premixing various SEBS with the mineral oil, the polypropylene, the ethylene-propylene copolymer and a proper amount of additives, and extruding through a double-screw extruder for pelletizing. The hardness of the inner padding is less than or equal to 65A, and n-hexane evaporation residues are less than or equal to 2000mg/L.
Description
Technical field
The present invention is the technical field that modifying plastics is processed, and particularly relates to a kind of TPE bottle cap material that is applicable to milk-product.
Background technology
TPE(Thermoplastic Elastomer) be a kind of snappiness with rubber, high strength, high resilience, has again the material of feature that can injection molding, applies to widely in bottle cap sheet.But for the consideration of food sanitation safe (especially milk-product) country has been put into effect to the standard of some row.Especially the project of the normal hexane residue on evaporation in GB 4805.
Summary of the invention
The object of the present invention is to provide a kind of multiple SEBS and mineral oil, polypropylene, ethylene propylene polymerization thing and appropriate additive of adopting by premix, then through the TPE of twin screw extruder extruding pelletization product.Hardness≤the 65A of this product, normal hexane residue on evaporation≤2000mg/L.
The TPE product that is applicable to milk-product provided by the invention, it mainly comprises the feed composition by following parts by weight proportioning:
Wherein, the SEBS that described SEBS-1 is a kind of linear high molecular weight; SEBS-2 is the SEBS of high molecular in a kind of linearity; SEBS-3 is the low-molecular-weight SEBS of a kind of star.
Preparing formula optimization weight of the present invention (part) proportioning is:
Preparing formula optimization weight of the present invention (part) proportioning is:
The present invention adopts multiple SEBS and mineral oil, polypropylene, ethylene propylene polymerization thing and appropriate additive by premix, then through twin screw extruder extruding pelletization.Hardness≤the 65A of this product, normal hexane residue on evaporation≤2000mg/L.
Embodiment
Below by case study on implementation, further illustrate the present invention.
Case 1:
By SEBS and mineral oil, polypropylene, ethylene propylene polymerization thing and appropriate additive component, by following component formula, all raw materials are put into high speed mixer and carry out blend:
Again this blend composition is added mixing granulator in twin screw extruder to be dunnage in the TPE that is applicable to milk-product, gained TPE.
Product performance test is as shown in table 1 below.
Table 1: for dunnage performance test table in the TPE of milk-product

| Tensile strength | 8.7MPa |
| Elongation at break | Be greater than 550% |
。
Case 2
By SEBS and mineral oil, polypropylene, ethylene propylene polymerization thing and appropriate additive component, by following component formula, all raw materials are put into high speed mixer and carry out blend:
This blend composition is added mixing granulator in twin screw extruder to be dunnage in the TPE that is applicable to milk-product, the test of gained TPE product performance is as shown in table 2 below again.
Table 2: for dunnage performance test table in the TPE of milk-product
| Test event | Result |
| Melting index (230 degree, 5 kilograms) | 12.54g/10min |
| Hardness | 60A |
| Normal hexane residue on evaporation | 1600mg/L |
| Tensile strength | 8.1MPa |
| Elongation at break | Be greater than 550% |
。
The above, such scheme of the present invention all can only think explanation of the present invention can not limit the present invention, claims have been pointed out scope of the present invention, and scope of the present invention is not pointed out in above-mentioned explanation, therefore, be implication that claims of the present invention are suitable and any change in scope, all should think to be included in the scope of claims.
