Abstract
The invention discloses plastic synthetic paper, comprising an inner layer, an outer layer and a middle layer, wherein, the inner layer and the outer layer comprise the following raw materials by weight percentage: 25 to 35% of CaCO3, 35% to 45% of low-voltage linear polyethylene, 20% to 30% of imitation paper master batch and 10% to 20% of white master batch; the middle layer comprises the following raw materials by weight percentage: 40% to 70% of linear low density polyethylene, 20% to 50% of CaCO3 and 10% to 20% of white master batch. The reasonable proportion and interaction of each component greatly improve the tensile strength of products, simultaneously improve the environmental stress cracking resistance, low temperature impact resistance and warp resistance of products; the surface finish is good, thereby being easier to write and completing the printing only by existing fiber paper ink and equipment; compared with the prior art, the invention features simple printing process, less time and labor consumption, no need of specific ink and specific printing equipment, thereby greatly reducing the printing cost of products.
Description
Technical field:
The present invention relates to a kind of plastic synthetic paper, the plastic synthetic paper of especially a kind of hot strength height, good, the available common ink printing of surface smoothness.
Background technology:
Water-fast, oil resistant, chemicals-resistant burn into are anti-aging, anti-insect because plastic synthetic paper has, stretch-proof and be easy to advantage such as long-term storage, have been widely used in writing, printing and package paper etc.Because of existing plastic synthetic paper adopt more PP (polypropylene) for primary raw material in addition material such as auxiliary agent make, when being printing, maximum defective can not use fibrous paper to need ink special with printing-ink, to such an extent as to the special-purpose printing equipment of essential use, not only cost height, and typography process complexity.
Summary of the invention:
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, the plastic synthetic paper of a kind of hot strength height, good, the available common ink printing of surface smoothness to be provided.
Technical solution of the present invention is: a kind of plastic synthetic paper, constituted by inside and outside layer and intermediate layer, and raw material and the percentage by weight of described inside and outside layer are CaCO
325～35%, low-voltage line property polyethylene 35%～45%, imitative paper masterbatch 20%～30% and white master material 10%～20%, the raw material in described intermediate layer and percentage by weight are LLDPE 40%～70%, CaCO
320%～50% and white master material 10%～20%.
The raw material of described imitative paper masterbatch and percentage by weight are CaCO
320～35%, TiO
210～15%, high density polyethylene (HDPE) 30～40%, low density polyethylene (LDPE) 10～15% and auxiliary agent surplus.
Each component rational proportion of the present invention, interaction have improved the hot strength of product greatly, have also improved environmental stress crack resistance, low-temperature impact resistance and the anti-warpage properties of product simultaneously; Surface smoothness is good, is easier to write, as long as can finish printing with existing fibrous paper with printing-ink, equipment, it is simple to compare typography with prior art, time saving and energy saving, need not ink special, special-purpose printing equipment, greatly reduce the printing cost of product.
The specific embodiment:
The production technology of the embodiment of the invention is identical with the production technology of existing three layers of composite membrane, namely by three-layer co-extruded inflation film manufacturing machine, through mixed material, screw rod shearing, melt to die head and extrude, get final product by operations such as inflation, cooling, rotation traction traction, cutting rollings.
Key is the batch mixing step, and raw material and the percentage by weight of described inside and outside layer are CaCO
325～35%, low-voltage line property polyethylene 35%～45%, imitative paper masterbatch 20%～30% and white master material 10%～20%, each composition weight sum is 100%.The raw material in described intermediate layer and percentage by weight are LLDPE 40%～70%, CaCO
320%～50% and white master material 10%～20%, each composition weight sum is 100%.
Raw materials used equal buyable, but the granularity of product should be superfines, should satisfy the requirement of plastic film blowing machine.
Raw material and the percentage by weight of used imitative paper masterbatch are preferably CaCO
320～35%, TiO
210～15%, high density polyethylene (HDPE) 30～40%, low density polyethylene (LDPE) 10～15% and auxiliary agent surplus, each composition weight sum is 100%.Auxiliary agent can be with at least a with in coupling agent, stabilizing agent, plasticizer and the lubricant of existing plastics-production.
Embodiment of the invention pull-off force with prior art to such as table 1:
