Description
Technical field
The present invention relates to pulp technology for making paper, specifically a kind of preparation method of environmental protection package paper.
Background technology
As the development of society, humanistic culture also improve constantly, various red-letter days are also to come thick and fast, and so far must
Few is exactly festive gift, and the packaging of gift is then to show present value and exquisite best external expression.But it is conventional at present
Wrapping paper cause that water-resistance is poor, rough surface due to its fiber essential reason, it is impossible to meet the demand of client, one manufactured for this
The environmental protection package paper with stronger water-resistance and solvent resistance and the bright-coloured light of surface color is planted extremely to be necessary.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided one kind has stronger water-resistance and solvent resistance and surface
The preparation method of the environmental protection package paper of bright-colored light.
In order to achieve the above object, the present invention devises a kind of manufacture method of environmental protection package paper, comprises the following steps：It is former
Paper is manufactured paper with pulp, chromatograph is coated with, embossed and surface layer are coated with, it is characterised in that：
The surface layer coating, comprises the following steps：
Step 1, completes the preparation of investment precoat in a reservoir, and investment precoat is by weight ratio by 80-100 parts
Gloss oil, the scratch resistance agent composition of 0-20 parts of water and 0-4 part, the gloss oil is polyacrylate resin or polyurethane resin.Institute
It is a kind of trifunctional group cross-linking agent to state scratch resistance agent；
Step 2, is put into embossed paper in Kohler coater, using feeding roller by by the face after 200 mesh sieve net filtrations
Coating applies on paper, with airblade coating by coating weight control in 8-15g/m2, while using blast 7-12kPa's
Air knife blows out unnecessary coating, forms coating, and temperature in use will be after 110-130 DEG C of drying room will complete surface layer coating afterwards
Dried to 4%-6% into paper moisture, form environmental protection package paper, and wind preservation；
The body paper is manufactured paper with pulp, and is comprised the following steps：
Step 1, the preparation of slurry：Prepared including slurry, prepared by dyestuff, auxiliary material liquid is prepared and with slurry；
（1）It is 1 from ratio：The masson pine that 1 softwood pulp and hardwood pulp is made, will bleach sulphur
