Abstract
The invention discloses a water absorbent for papermaking, relating to the technical field of papermaking. The water absorbent for papermaking is prepared from the following raw materials in parts by weight: 20-30 parts of polyvinyl alcohol, 23-28 parts of starch grafted copolymer, 5-10 parts of sorbitol, 2-6 parts of succinic acid, and 1-5 parts of sodium carbonate. The water absorbent for papermaking is prepared from polyvinyl alcohol, starch grafted copolymer, sorbitol, succinic acid and sodium carbonate, and the prepared water absorbent can be used for fast absorbing water while being used for enhancing the wet strength and dry tensile strength of paper.
Description
Technical field
The present invention relates to pulp technology for making paper, especially a kind of paper grade (stock) water absorbing agent.
Background technology
The paper products such as toilet paper and napkin paper require to have good water imbibition, also to possess good wet strength simultaneously, existing however have there is the wet strength that good absorptive paper making additive all can reduce paper, this is because wet strength agent increases the wet strength of paper often by the hydrophobicity increasing paper surface, due to the introducing of hydrophobic group, the water-taking efficiency of water absorbing agent is reduced, effectively can not absorb water.In order to address these problems, there is researcher to pass through to add surfactant and solve effect between wet strength agent and water absorbing agent, but these reagent can cause the intensity of paper to reduce, therefore, urgently there is good water imbibition and do not reduce the water absorbing agent of effect because of the effect of wet strength agent.
Summary of the invention
The object of this invention is to provide a kind of paper grade (stock) water absorbing agent, this paper grade (stock) water absorbing agent can solve water absorbing agent reduces effect problem by the impact of wet strength agent.
In order to solve the problem, the technical solution used in the present invention is:
This paper grade (stock) water absorbing agent is prepared from by the raw material of following parts by weight: polyvinyl alcohol 20 parts ~ 30 parts, starch graft copolymer 23 parts ~ 28 parts, sorbierite 5 parts ~ 10 parts, butanedioic acid 2 parts ~ 6 parts, 1 part ~ 5 parts, sodium carbonate.
In technique scheme, technical scheme can also be more specifically: the parts by weight of described raw material are: polyvinyl alcohol 20 parts, starch graft copolymer 28 parts, sorbierite 7 parts, butanedioic acid 6 parts, 3 parts, sodium carbonate.
Further, the parts by weight of described raw material are: polyvinyl alcohol 25 parts, starch graft copolymer 25 parts, sorbierite 5 parts, butanedioic acid 4 parts, 1 part, sodium carbonate.
Further, the parts by weight of described raw material are: polyvinyl alcohol 30 parts, starch graft copolymer 23 parts, sorbierite 10 parts, butanedioic acid 2 parts, 5 parts, sodium carbonate.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This paper grade (stock) water absorbing agent is prepared from by polyvinyl alcohol, starch graft copolymer, sorbierite, butanedioic acid, sodium carbonate, and the water absorbing agent obtained can absorb moisture fast while the wet strength increasing page and dry tensile strength.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
