Abstract
The present invention discloses a retention assisting reinforcing agent for papermaking, wherein the retention assisting reinforcing agent comprises, by weight, 5-10 parts of chitosan, 20-30 parts of polyacrylamide, 3-5 parts of a charge modifying agent, 1-3 parts of a surfactant, 1-3 parts of a cross-linking agent, a pH value adjusting agent, and 50-60 parts of a dispersion medium, wherein the use amount of the pH value adjusting agent is determined in the way that the pH value of the retention assisting reinforcing agent is 5-7. The present invention further discloses a preparation method of the retention assisting reinforcing agent. According to the present invention, the retention assisting component and the reinforcing component are compounded, and the main function components are modified with the charge modifying agent, the surfactant and the like, such that the active groups of the main function components are increased so as to concurrently improve the retention assisting effect and the reinforcing effect, and further improve the softness and the whiteness of the paper.
Description
Technical field
The present invention relates to a kind of fortifier for papermaking and preparation method thereof, belong to paper making additive technical field.
Background technology
Modern paper industry generally adopts glidant and the performance of reinforcing agent to paper to control respectively.But, current glidant and reinforcing agent in the process used, the inaccurate coordination of two kinds of auxiliary agents, object cannot be unified, if glidant addition is large, then paper strength will be weakened, and if paper strength increases, then the retention effect of paper is just very poor.Therefore, need a kind of novel fortifier for papermaking to improve the problems referred to above.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide fortifier for papermaking that a kind of retention effect is good, intensity is high and preparation method thereof.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of fortifier for papermaking, is characterized in that, comprises following component and the parts by weight of each component are respectively:
Shitosan: 5-10 part;
Polyacrylamide: 20-30 part;
Charge modifiers: 3-5 part;
Surfactant: 1-3 part;
Crosslinking agent: 1-3 part;
PH adjusting agent: consumption is the pH value of adjustment fortifier for papermaking is 5-7;
Decentralized medium: 50-60 part.
Further preferably, a kind of fortifier for papermaking described in root, comprises following component and the parts by weight of each component are respectively:
Shitosan: 10 parts;
Polyacrylamide: 30 parts;
Charge modifiers: 5 parts;
Surfactant: 3 parts;
Crosslinking agent: 3 parts;
PH adjusting agent: consumption is the pH value of adjustment fortifier for papermaking is 6;
Decentralized medium: 60 parts.
In addition, described charge modifiers is any one in quaternary ammonium salt, tertiary ammonium salt, sulphur ammonium.
Described surfactant is neopelex.
Described crosslinking agent is glycerine or epoxychloropropane.
Described decentralized medium is water or absolute ethyl alcohol.
Described pH adjusting agent is then hydrochloric acid.
A kind of preparation method of above-mentioned fortifier for papermaking, it is characterized in that, comprise the following steps: according to the parts by weight relation of each component, first shitosan, polyacrylamide, charge modifiers and surfactant are joined in decentralized medium and be uniformly mixed, then by mixed heating material to 90-100 DEG C, add crosslinking agent to continue to stir 2-3h, add pH adjusting agent after being finally cooled to room temperature, the overall pH value regulating fortifier for papermaking is 5-7.
Usefulness of the present invention is: the present invention is by carrying out composite to resident component and enhancing component, and by charge modifiers and surfactant etc., modification is carried out to above-mentioned primary functional components, the active group of primary functional components is increased, thus can improve retention simultaneously and strengthen effect, also can improve flexibility and the whiteness of paper simultaneously.
Detailed description of the invention
Below in conjunction with specific embodiment, concrete introduction is done to the present invention.
embodiment 1:
