Abstract
The invention discloses a paper pulp wet strength reinforcing agent and a preparation method of the paper pulp wet strength reinforcing agent. By weight, the reinforcing agent comprises 35-40 parts of polyamides, 7-8 parts of epoxy chloropropane, 0.1-0.3 parts of hydrochloric acid and 50-60 parts of water. The paper pulp wet strength reinforcing agent and the preparation method of the paper pulp wet strength reinforcing agent have the advantages that the wet strength reinforcing agent is simple in components, the preparation method is simple, the using effect is good, and the wet strength reinforcing agent has no harm to a human body and is safe and reliable. Meanwhile, the tensile strength of paper can be obviously promoted.
Description
Technical field
The present invention relates to a kind of paper pulp reinforcing agent, wet epistasis reinforcing agent of a kind of paper pulp and preparation method thereof specifically belongs to paper pulp reinforcing agent field.
Background technology
The intensity property of paper comprises that tensile strength, tearing strength, pop strength etc. are the important parameters of weighing page quality, and general industry paper using and paper for daily use all require page that certain intensity is arranged.The most important factor that affects paper strength is fibrous binding force (comprises that Hydrogenbond power, chemical bonded refractory are made a concerted effort, polar bond attraction, surface interweave power).Paper is to have layer structure, and in the plane, fiber is arranged in a jumble, and is interlaced, and take two-dimensional orientation as main, lean on molecular separating force and hydrogen bond in conjunction with main between layers, but the application point number is in layer.In paper plane, interconnect by Hydrogenbond two between cellulose molecular chain, make bundle dividing from, sub-wire, even cut into staple fibre by the making beating effect, the binding site between fiber and fiber is increased, thereby give page certain intensity.
But because being actually to be assembled by the very strong cellulose of strand rigidity, cellulose fibre forms, the physical entanglement effect that reaches between molecular beam between strand is very little, make page adhesion between layers less, therefore this intensity of giving page by making beating is limited, and needs interpolation auxiliary agent improves the intensity of page.According to the impact size of water on paper strength, the intensity of page can be represented with dry strength and wet strength respectively, corresponding auxiliary agent is dry strength agent and wet strength agent.
Summary of the invention
In order to address the above problem, the present invention has designed wet epistasis reinforcing agent of a kind of paper pulp and preparation method thereof, and this reinforcing agent composition is simple, the preparation method is simple, and result of use is good, and to human body without harm, safely, reliably, can significantly improve the TENSILE STRENGTH of paper.
Technical scheme of the present invention is:
A kind of paper pulp epistasis reinforcing agent that wets is grouped into by the one-tenth of following weight portion:
Kymene 5-40 part, epoxychloropropane 7-8 part, hydrochloric acid 0.1-0.3 part, water 50-60 part.
Preferably: 7 parts of kymenes, 7.5 parts of epoxychloropropane, 0.2 part of hydrochloric acid, 55 parts, water.
The compound method of the wet epistasis reinforcing agent of above-mentioned paper pulp is:
By each composition of said ratio weighing; Polyamide is stirred in water, and drip epoxychloropropane, stir evenly rear hydrochloric acid adjust pH to 4～5 of using, obtain product.
This reinforcing agent consumption is 2% of paper pulp fiber quality, make that medical papery ground is soft, nontoxic, water imbibition by force, nonirritant, do not fall fiber, wet strength high, can replace hospital gauze and absorbent cotton.
The invention has the advantages that: wet epistasis reinforcing agent composition is simple, and the preparation method is simple, and result of use is good, and to human body without harm, safety, reliable simultaneously, can significantly improve the TENSILE STRENGTH of paper.
