Description

A kind of waterproof kraft paper and preparation method thereof
Technical field
The present invention relates to a kind of waterproof kraft paper and preparation method thereof.
Background technology
Brown paper is widely used in chemical industry, machinery and food packaging industry, and the packaging of food will follow what is be convenient for carrying Principle, brown paper stretch-proof advantage are especially suitable for the demand of packaging, in order to prevent packaging bag to be pulled off, it requires packaging material There is good tensile strength.Because the heterogeneity of various food, the various resistances of required packaging bag have certain requirement, The simply tensile strength that existing brown paper is more considered, and ignore other performances.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of low production cost, and the calendaring effect is good, have heat resistance Can, pull resistance is strong, is unlikely to deform, oil resistant positive effect, the more environmentally friendly waterproof kraft paper of production process.
To solve the above problems, the present invention is achieved through the following technical solutions：A kind of waterproof kraft paper, the waterproof Brown paper is made up of following weight composition:Wood pulp 70-115 parts, polyethylene 3-7 parts, starch 9-15 parts, distilled water 33-54 parts, dispersant 0.1-0.9 parts, polyester modification dimethicone 3-11 parts, asbestos 11-17 parts, calcium carbonate 1-3 parts, pine Fragrant 0.3-2 parts, sodium peroxide 1-7 parts and bast fiber 3-6 parts.
Another technical problem to be solved by this invention is to provide a kind of preparation method of waterproof kraft paper,
The present invention is achieved through the following technical solutions：The preparation process of the waterproof kraft paper is as follows：
1) extraction wood pulp 70-115 parts, polyethylene 3-7 parts, distilled water 33-54 parts are beaten by weight ratio；
2) dispersant 0.1-0.9 parts, asbestos 11-17 parts, calcium carbonate 1-3 parts, rosin 0.3-2 are extracted by weight ratio Part, sodium peroxide 1-7 parts and bast fiber 3-6 parts are added in the slurry of step 1, are stirred with glass bar；
3) slurry obtained in step 2 is subjected to wet end forming processes；
4) slurry being molded in step 3 is squeezed；
5) it is dried after step 4 squeezing；
6) starch 9-15 parts are added after step 4 drying and polyester modification dimethicone 3-11 parts carry out surface and applied Glue；
7) it is dried again after step 6 is glued and is shaped to brown paper with superpressure.
The beneficial effect of waterproof kraft paper of the present invention is：Rosin, the asbestos added in the waterproof kraft paper preparation process And bast fiber, improve the intensity and toughness of body paper；The starch and polyester modification dimethicone added outside in applying glue The surface water-resistance energy and oil-resistant characteristic of paper are improved well；Superpressure processing makes paper strength more preferable, also reduces simultaneously Energy consumption.
