Description

A kind of plastic sheet and preparation method thereof for luggage
Technical field
The present invention relates to case board technical fields, specifically disclose a kind of for the plastic sheet of luggage and its preparation side Method.
Background technique
With people life and the level of consumption continuous improvement, various luggages have become people at one's side can not or Scarce ornaments.People require luggage product not only to be reinforced on practicability, and dicoration has become main expansion.
According to the change of consumer's grade, the material of luggage is more diversified, the matter such as corium, PU, terylene, canvas, linen-cotton Ground luggage trend ahead of fashions.Meanwhile in the epoch for increasingly bragging about individual character, all kinds of styles such as brief, pseudo-classic, cartoon are also never The ipsilateral personage that panders to the trend of the times makes widely known the demand of individual character.The style of luggage also by traditional business case, school bag, traveling bag, wallet, Sachet etc. is expanded.
Meanwhile being currently used in the material of production luggage, though corium material soft feel is good, intensity is inadequate, at high cost, Though cloth material is light-weight but sizing is poor, though plastic cement material has some strength, sense of touch is hard, and pliability is inadequate.
Based on the above technological deficiency, it is necessary to develop one kind and have a some strength, while surface layer it is soft for luggage Plastic sheet.
Summary of the invention
Based on this, it is necessary to be directed to prior art problem, provide a kind of plastic sheet for luggage, have one in plate On the basis of determining mechanical strength, enhance surface layer pliability, promote sense of touch, the present invention discloses the plastic plates that this is used for luggage The preparation method of material.
To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:
A kind of plastic sheet for luggage, including base layer and surface layer, the base layer by following parts by weight component Be made: base layer and surface layer including integrated co-extrusion modling, the base layer are PP alloy-layer, and the surface layer is TPO/POE/ PP/EPDM blending type thermoplastic dynamic vulcanization glue.
Preferably, the PP alloy-layer squeezes out after being blended by the component melts of following parts by weight: PP:85-95 parts, PE:5-15 parts, auxiliary agent: 0.5-2 parts, wherein the auxiliary agent include cumyl peroxide, antioxidant 1010, styrene and 1,4 butanediol diacrylate.
Preferably, the TPO/POE/PP/EPDM blending type thermoplastic dynamic vulcanization glue is total to by the component of following parts by weight It is squeezed out after mixed dynamic vulcanization: TPO:30-50 parts, POE:10-40 parts, PP:10-30 parts, EPDM:10-50 parts, BIBP: 0.1-0.5 parts, TAIC:0.1-0.3 parts, brominated phenolic resin: 0.1-1 parts.
Preferably, the PP reclaimed materials in the PP is not less than 40wt%, and the PE reclaimed materials in the PE is not less than 30wt%.
In addition, a kind of preparation method of the plastic sheet for luggage, includes the following steps,
Stock: prepare the component of following parts by weight as raw material 1, PP:85-95 parts, PE:5-15 parts, auxiliary agent: 0.5-2 parts； Prepare the component of following parts by weight as raw material 2, TPO:30-50 parts, POE:10-40 parts, PP:10-30 parts, EPDM:10-50 Part, BIBP:0.1-0.5 parts, TAIC:0.1-0.3 parts, brominated phenolic resin: 0.1-1 parts.
Melt blending: the raw material 1 and the raw material 2 are put into two screw machines respectively, heating melting is blended；
Coextrusion: the raw material after melt blending enters molding die coextrusion production board via two screw machines Material.
The invention has the benefit that the present invention discloses a kind of plastic sheet for luggage, which has preferably Mechanical strength, while skin feel is soft, the texture and use feeling of luggage can be substantially improved, and disclosed a kind of for case The preparation method of the plastic sheet of packet, using multi-layer co-extruded technique, method is simple, is readily produced.
Specific embodiment
To further understand the features of the present invention, technological means and specific purposes achieved, function, lower mask body Present invention is further described in detail for embodiment.
The present invention relates to a kind of plastic sheets for luggage, base layer and surface layer including integrated co-extrusion modling, base Body layer is PP alloy-layer, and surface layer is TPO/POE/PP/EPDM blending type thermoplastic dynamic vulcanization glue.
