preparation example Construction

[0023] The preparation method of the hyperbranched polypropylene butene copolymer is as follows: propylene butene is catalyzed by an ethylene acenaphthylene (α-diimine) nickel catalyst, and a chain transfer agent is added to polymerize to obtain the hyperbranched polypropylene butene copolymer.

[0024] Polyamide A: prepared from terephthalic acid and succinic acid.

[0025] Polyamide B: prepared from p-phenylenediamine and adipic acid.

[0026] The inorganic filler is silicon dioxide; the foaming agent is polytrimethylene terephthalate.

Embodiment 1

[0028] The composition of the upper surface layer and the lower surface layer includes: 20 parts of metallocene polyethylene, 20 parts of polyamide A, 5 parts of inorganic filler, and the thickness is 20um;

[0029] The composition of the upper surface layer and the lower surface layer includes: 35 parts of hyperbranched polypropylene-butene copolymer, 35 parts of propylene terpolymer A, 8 parts of inorganic filler, and the thickness is 30um;

[0030] The core layer is 45 parts of isotactic polypropylene, the thickness is 20um, and 10 parts of foaming agent.

Embodiment 2

[0032] Same as Example 1, except that metallocene polyethylene is replaced by common polyethylene.

Abstract

The invention provides multilayer synthetic paper with high needling strength and tensile strength. The multilayer synthetic paper is low in cost and comprises an upper surface layer, an upper secondary surface layer, a core layer, a lower secondary surface layer and a lower surface layer, wherein the upper surface layer and the lower surface layer comprise 10-30 parts of metallocene polyethylene,10-30 parts of polyamide and 5-10 parts of an inorganic filler, and have the thickness of 10-30 [mu]m, the upper secondary surface layer and the lower secondary surface layer comprise the following components in parts by weight: 20-50 parts of hyperbranched polypropylene-butylene copolymer, 20-50 parts of propylene terpolymer and 5-10 parts of an inorganic filler, and have the thickness of 20-40[mu]m, and the core layer is made of 40-50 parts of isotactic polypropylene, has the thickness of 20-40 [mu]m, and is optionally made of 0-20 parts of a foaming agent. The multilayer synthetic paper is high in needling strength and tensile strength, low in cost and suitable for being applied to different occasions.

Description

technical field [0001] The invention relates to the field of synthetic paper preparation, in particular to a low-cost polyolefin synthetic paper and a preparation method thereof, belonging to the technical field of synthetic paper materials. Background technique [0002] Synthetic paper, also known as polymer paper or plastic paper, has no clear definition yet. However, it is generally believed that synthetic paper is made of synthetic resin (such as polyethylene, polypropylene, polystyrene, etc.) The properties—especially the appearance properties such as whiteness and opacity, as well as printing adaptability and adhesive adaptability, etc., the resulting materials. The emergence of synthetic paper stems from three reasons. First of all, the rapid increase in the demand for paper in the fast-growing economy has led to a skyrocketing price of pulp; second, ordinary paper has various defects, such as water resistance, etc., and synthetic paper can make up for these defects...
