Abstract
The invention discloses a kind of coating of waterproof paper bag and preparation method thereof, it is related to paper products technical field, includes the raw material of following part meter：60 ~ 70 parts of 55 ~ 65 parts of diatomite, 45 ~ 55 parts of modified soluble nano silicone colloidal sol, 35 ~ 40 parts of fatty acid distribution of coconut oil, 25 ~ 27 parts of polyacrylonitrile fibre, 23 ~ 25 parts of polyethylene, 20 ~ 22 parts of mould proof composition, 15 ~ 20 parts of waterproofing agent, 10 ~ 15 parts of auxiliary agent and deionized water.The present invention is directly coated on paper surface, and firm attachment, no vestige with good water resistance, is effectively protected paper bag, prepared simply, cheap, can carry out large-scale production, safety non-toxic, environmental protection will not be detrimental to health.
Description
Technical field
The present invention relates to paper products technical field, and in particular to a kind of coating of waterproof paper bag and preparation method thereof.
Background technology
Food bag is the bag for being used to contain food, is divided from material, including paper foodstuff bag and plastic-food
Bag.Food-packaging bag has the characteristic of excellent mechanical property, anticorrosion and waterproof, but food-packaging bag is difficult to decompose, and
It does not meet instantly environmentally friendly theory；And requirement of the paper foodstuff bag due to excellent degradability, complying fully with environmental protection,
Therefore, it is possible to be able to use on a large scale.
Although paper foodstuff bag has excellent degradability, for the mechanical performance of food bag is compared with food-packaging bag
It is poor, especially water resistance, so as to cause paper foodstuff bag to occur rupturing and meeting the damaged situation of water in use
Occur, significantly limit and further promote and use.
The content of the invention
It is an object of the invention to provide a kind of coating of waterproof paper bag and preparation method thereof, paper surface is directly coated on
, firm attachment, no vestige with good water resistance, effectively protects paper bag, prepares simple, cheap, Ke Yijin
Row large-scale production, safety non-toxic, environmental protection will not be detrimental to health.
The invention provides following technical scheme：A kind of coating of waterproof paper bag, includes the raw material of following part meter：Silicon
55 ~ 65 parts of diatomaceous earth, 45 ~ 55 parts of modified soluble nano silicone colloidal sol, 35 ~ 40 parts of fatty acid distribution of coconut oil, polyacrylonitrile fibre 25 ~ 27
Part, 23 ~ 25 parts of polyethylene, 20 ~ 22 parts of mould proof composition, 15 ~ 20 parts of waterproofing agent, 10 ~ 15 parts of auxiliary agent and deionized water 60 ~ 70
Part；
The modified soluble nano silicone colloidal sol includes the raw material that following part is counted：25 ~ 35 parts of water-soluble nanoscale silica sol, receive
2 ~ 8 parts of 0 ~ 12 part of rice silica 1 and iron oxide；
The auxiliary agent includes the raw material that following part is counted：2 ~ 6 parts of surfactant, 2 ~ 4 parts of coalescents, 2 ~ 3 parts of water-loss reducer, froth breaking
1 ~ 2 part of agent, 0.2 ~ 0.8 part of light stabilizer, 0.2 ~ 0.6 part of age resistor, 0.2 ~ 0.4 part of adhesion promoter, crosslinking agent 0.2 ~ 0.4
