Abstract
The rosin size mainly for paper pulp is prepared with low-foaming compound emulsifier, low foaming stabilizer, modified resin and water. It has less foams and good gluing effect and its use can raise paper quality, improve the operation of papermaking machine and reduce amount of treated circular water.
Description
The present invention relates to a kind of low bubble, dispersion rosin size efficiently, be mainly used in paper industry, also can be used as tackifier and add in the tackiness agent as internal sizing agent.
At present, as one of principal item of internal sizing agent, be exactly " dispersion rosin size " in the domestic paper industry, claim the emulsion rosin sizing agent again, dispersed common resin, rosin series sizing agent.PH value (pH value when copying paper) when using by it in this type of sizing agent is divided into (acidity) rosin sizing agent (rosin series acid accumulator size) and rosin series neutral sizing agent.What present domestic most of paper plant used is (acidity) rosin sizing agent.This series products in use, ubiquitous problem is that foam is many, sizing efficiency is good inadequately, has both influenced paper quality, has simultaneously also caused the difficulty in the paper machine operation, has also increased the weight of the workload of circulating water treatment in addition.Though taked many technical measures for this reason, as adding defoamer in use, because this is the sizing agent essential problem that employed emulsifying agent, stablizer etc. bring in manufacturing processed, so effect is all not ideal enough.
The objective of the invention is provides a kind of foam lower in order to overcome the deficiency of above-mentioned prior art, and sizing efficiency is better, can improve paper quality, improves paper machine operation, can effectively improve paper quality, reduces the dispersion rosin size of circulating water treatment workload.
For overcome existing low molecule emulsifying agent, stablizer is easy to generate foam, the imperfect problem of sizing efficiency, consider that macromolecule emulsifier is difficult for producing foam, but its emulsifying property a little less than, otherwise low molecule emulsifying agent emulsifying property is good, and easily produce a large amount of foams, the present invention through molecular designing and repeatedly optimum combination selected a kind of novel mixed emulsifier.This mixed emulsifier makes two or more emulsifying agent bring into play good synergism each other, is aided be difficult for to produce the low bubble of foamy emulsion stabilizer again, more makes final sizing agent product have low bubble, efficient, stable characteristics.Wherein during a certain emulsifying agent, its effect is all superior than single use in this combination.The objective of the invention is to realize by following technical solution.
This low bubble, dispersion rosin size efficiently, form by following component (weight part):
