Abstract
The invention discloses a kind of internal sizing agents, the product belongs to chemical industry field of papermaking, produce the raw material that the product uses includes: modified rosin resin 34-36% by weight ratio, tall oil 50-52%, paraffin 6%, macromolecule dispersing agent 2%, fungicide 1%, barium stearate 1%, sodium alkyl benzene sulfonate 4%, pass through the method next life pulp production sizing agent blended at a certain temperature, the product processes are simple, it is to make an addition to sizing agent in paper pulp in mashing or ingredient when use, this kind of sizing agent has hydrophilic radical and hydrophobic grouping, outside is set to be orientated hydrophobic grouping in fiber surface, make paper hydrophobic property and resist fluids permeability, paper water resistant can be improved, oil resistant, the performances such as anti-printing ink, slickness can be improved simultaneously, hydrophobicity, printing adaptability.
Description
Technical field:
Product of the present invention belongs to papermaking chemical field more particularly to a kind of paper making pulps sizing agent.
Background technique:
Sizing agent is also known as cementing agent, is a kind of additive for paper making.Paper and the anti-ink of cardboard, water resistant, anti-lotion, anticorrosive etc. can be assigned
Performance simultaneously can improve smoothness, intensity and application phase.Sizing agent can be divided into internal sizing agent and Cypres.Internal sizing agent
It is roughly divided into rosin series sizing agent, synthetic sizing agent and neutral sizing agent three categories.Cypres generally use anionic
Polymer substance.Product of the present invention is a kind of interior neutral sizing agent of rosin series slurry, is to add sizing agent in mashing or ingredient
In in paper pulp, this kind of sizing agent has hydrophilic radical and hydrophobic grouping, so that outside is orientated hydrophobic grouping in fiber surface, makes
Paper hydrophobic property and resist fluids permeability can be improved the performances such as paper water resistant, oil resistant, anti-printing ink, while light can be improved
Slip, hydrophobicity, printing adaptability.
Summary of the invention:
Present invention mainly solves the problem of be to provide a kind of internal sizing agent and its production method, produce the raw material that the product uses
It by weight ratio include: modified rosin resin 34-36%, tall oil 50-52%, paraffin 6%, macromolecule dispersing agent 2%, fungicide
1%, barium stearate 1%, sodium alkyl benzene sulfonate 4%.
The present invention can be achieved through the following technical solutions:
(1) tall oil of formula ratio is added in reaction vessel, temperature is increased to 35-40 DEG C, blender stirring is started, while stirring
The modified rosin resin that formula ratio is slowly added in side is mixed, is stirred evenly.
(2) it is cooled to room temperature, by the paraffin of formula ratio, macromolecule dispersing agent, fungicide, barium stearate, alkyl benzene sulphonate
Sodium is added in reaction vessel simultaneously, continues to obtain finished product after being stirred to react 0.2-0.3 hours.
Preferably, the solid content of the modified rosin resin is 92%.
Preferably, the tall oil purity is 90%.
The beneficial effects of the present invention are: providing a kind of internal sizing agent, the product processes are simple, when use be
Sizing agent is made an addition in paper pulp when mashing or ingredient, this kind of sizing agent has hydrophilic radical and hydrophobic grouping, in fiber table
Face makes outside be orientated hydrophobic grouping, makes paper hydrophobic property and resist fluids permeability, paper water resistant, oil resistant, anti-print can be improved
The performances such as brush ink, while slickness, hydrophobicity, printing adaptability can be improved.
Specific embodiment
Embodiment 1
The tall oil that total amount is 50% will be accounted for be added in reaction vessel, temperature is increased to 35 DEG C, blender stirring is started, while stirring
Mix side be slowly added account for total amount be 36% modified rosin resin, stir evenly；It is cooled to room temperature, stone of the total amount for 6% will be accounted for
Wax accounts for macromolecule dispersing agent that total amount is 2%, accounts for fungicide that total amount is 1%, accounts for barium stearate that total amount is 1%, accounts for total amount and is
4% sodium alkyl benzene sulfonate is added in reaction vessel simultaneously, continues to obtain finished product after being stirred to react 0.2 hour.
Embodiment 2
The tall oil that total amount is 51% will be accounted for be added in reaction vessel, temperature is increased to 37.5 DEG C, starts blender stirring, side
Stirring side, which is slowly added, accounts for the modified rosin resin that total amount is 35%, stirs evenly；It is cooled to room temperature, will account for total amount is 6%
Paraffin accounts for macromolecule dispersing agent that total amount is 2%, accounts for fungicide that total amount is 1%, account for barium stearate that total amount is 1%, account for total amount
It is added in reaction vessel simultaneously for 4% sodium alkyl benzene sulfonate, continues to obtain finished product after being stirred to react 0.25 hour.
Embodiment 3
The tall oil that total amount is 52% will be accounted for be added in reaction vessel, temperature is increased to 40 DEG C, blender stirring is started, while stirring
Mix side be slowly added account for total amount be 34% modified rosin resin, stir evenly；It is cooled to room temperature, stone of the total amount for 6% will be accounted for
Wax accounts for macromolecule dispersing agent that total amount is 2%, accounts for fungicide that total amount is 1%, accounts for barium stearate that total amount is 1%, accounts for total amount and is
4% sodium alkyl benzene sulfonate is added in reaction vessel simultaneously, continues to obtain finished product after being stirred to react 0.3 hour.
