Abstract
The present invention relates to a kind of stone paper composite sheet for being used to pack electronic product and preparation method thereof, utilize multilayered molten co-extrusion general principle, by stone paper substrate, maleic anhydride grafted resin layer and linear polyethylene layer distinguish reactive extrursion, then by three one polymer it is hot-forming, cooling, winding.Production technology of the present invention, simple in construction, convenient operation and control, steady quality, production efficiency is high, has wide industrialization and market prospects.The structure that gained of the invention is used for the stone paper composite sheet for packing electronic product is simple, the electronic product for pack packaging pallet obtained after plastic uptake of the present invention using thermoforming machine, and being rubbed in transport process by vibrations, it is small to be influenceed, and will not produce plastic powders.The electronic product effectively quality requirement of protection electronic product, and poisonous and harmful substances will not be produced in process of production, recyclable recycling of leftover pieces, beneficial to environmental protection during production transport process and long-distance transport can be met.
Description
Technical field
Present invention relates particularly to stone papermaking technical field, especially it is a kind of be used to packing high-accuracy electronic component make its by
Shake small stone paper composite sheet of frictional influence and preparation method thereof.
Background technology
Stone paper is a kind of new material between paper and plastics, and profit can be degraded and reclaim after product use
With secondary white pollution will not be caused.And very wide, the product up-gradation of environmental friendly material stone paper industry materials, skill upgrading,
The space that application field expands is very wide, is the extremely strong rising industry of a vitality.
Electronic product packaging of the prior art is generally adopted by plastic sheeting or on the basis of carton, wraps inside
Dress increase plastic foam, bubble film etc. make product reach shockproof purpose.In transport process is produced, due to electronic product with
The friction of outer packing, vibrations of jolting easily produce plastic powders, and powder enters inside electronic component and electronic product can be caused
Fatal infringement, the influence for high-accuracy electronic component are more serious.Therefore, it is necessary to solve the above problems.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides one kind makes it be rubbed by vibrations for packing high-accuracy electronic component
Wiping influences small stone paper composite sheet and preparation method thereof, its production technology, simple in construction, convenient operation and control, and quality is steady
Fixed, production efficiency is high, has wide industrialization and market prospects.
The present invention is achieved by the following technical solutions：A kind of stone paper composite sheet for being used to pack electronic product,
It is made up of stone paper substrate, maleic anhydride grafted resin layer and linear polyethylene layer, the stone ply of paper and linear polyethylene layer
Between be provided with maleic anhydride grafted resin layer.
The stone ply of paper is impact-resistant polystyrene stone ply of paper, and thickness is 0.3~2.0mm.
The stone ply of paper is made by the raw material of following mass parts：Inorganic particle 60-85 parts, processing aid 1-5 parts, anti-impact
Hit polystyrene（HIPS）10-39 parts.
The inorganic particle is talcum powder, dolomite dust, calcium carbonate, kaolin, montmorillonite, hydrotalcite, magnesium hydroxide, hydrogen
At least one of aluminum oxide, silica, titanium dioxide, zinc oxide, barium sulfate etc..
The processing aid is conven-tional adjuvants, such as coupling agent, stearic acid, paraffin, PE waxes, one kind in antioxidant or
It is several.
The maleic anhydride grafted resin layer is polyethylene and maleic anhydride graft-blending resin bed, thickness is 0.05~
0.1mm。
The maleic anhydride grafted resin layer is made by the raw material of following mass parts：Polyethylene（LDPE/LLDPE/HDPE）
100 parts, maleic anhydride（MAH）5 parts, cumyl peroxide（DCP）0.2 part.
The thickness of the linear polyethylene layer is 0.1~0.5mm.
Another object of the present invention is to provide a kind of preparation side for being used to pack the stone paper composite sheet of electronic product
Method, comprise the following steps：
（1）By the material preparation of following mass parts：Inorganic particle 60-85 parts, processing aid 1-5 parts, impact-resistant polystyrene
（HIPS）10-39 parts；Inorganic particle, processing aid, impact-resistant polystyrene are well mixed in super mixer, adds and squeezes
It is 0.3~2.0mm to go out reactive extrursion to thickness in machine, that is, obtains stone paper layer；
（2）By the material preparation of following mass parts：Polyethylene（LDPE/LLDPE/HDPE）100 parts, maleic anhydride（MAH）5 parts,
Cumyl peroxide（DCP）0.2 part；Polyethylene, maleic anhydride, cumyl peroxide are mixed in super mixer
Even, it is 0.05~0.1mm to add reactive extrursion to thickness in extruder, that is, obtains maleic anhydride grafted resin layer；
（3）By melt flow rate (MFR) control in 0.7-5.3g/10min linear polyethylene, addition extruder melting extrusion to thickness
Spend for 0.1~0.5mm, that is, obtain linear polyethylene layer；
（4）By stone ply of paper, maleic anhydride grafted resin layer, linear polyethylene layer through hot-forming, cooling, winding, make stone
It is maleic anhydride grafted resin layer between ply of paper and linear polyethylene layer, that is, obtains compound for the stone paper of packing electronic product
Sheet material.
Maleic anhydride grafts are a kind of conventional important basic organic chemical industry raw materials.It is mainly used in synthesizing unsaturated polyester (UP)
Resin, maleic anhydride are also the important intermediate of copolymer, beneficial to reaction modifier uses as coupling agent and again, in plastic collar
Domain tool has been widely used, and maleic anhydride grafting price is higher.
Linear polyethylene is nontoxic, tasteless, odorless milky white granules, has higher softening temperature and melting temperature,
The features such as intensity is big, good toughness, big, heat-resisting, cold resistance is good rigidity, also with good environmental stress crack resistance, impact resistance
The performances such as intensity, tear-resistant intensity, it is widely used in the fields such as industry and daily living article.
The advantages of present invention possesses and effect：Compared with prior art, the side that the present invention passes through multilayered molten coextru-lamination
Formula, realize solvent-free compound.Pass through the intensity and glossiness of stone ply of paper reinforcing sheet material Rotating fields；Pass through linear polyethylene layer
Make sheet material Rotating fields that there is stronger rub resistance ability；By maleic anhydride grafted resin layer, make stone ply of paper and linear poly- second
Alkene layer preferably bonds together, and maleic anhydride grafted resin layer has the function that buffering.Present invention omits granulating working procedure, drop
Low energy consumption, has saved production cost, has been more beneficial for promoting the use of for stone paper product.
The structure that gained of the invention is used for the stone paper composite sheet for packing electronic product is simple, incite somebody to action this using thermoforming machine
The electronic product of the packaging pallet packaging obtained after invention plastic uptake, is influenceed small, will not be produced in transport process by vibrations friction
Raw plastic powders.It can meet that electronic product effectively protects the quality of electronic product during production transport process and long-distance transport
It is required that and poisonous and harmful substances, the recyclable recycling of leftover pieces, beneficial to environmental protection will not be produced in process of production.
