AI Technical Summary

Problems solved by technology

[0003] However, since cellulose fibers are actually composed of cellulose with strong molecular chain rigidity, the physical entanglement between molecular chains and molecular bundles is very small, so that the bonding force between paper layers is small. , so the strength of the paper sheet by beating is limited, and it is necessary to add additives to improve the strength of the paper sheet

Embodiment 1

[0015] A pulp reinforcing agent, consisting of the following components by weight:

[0016] 1.8 parts of NaOH, 22 parts of sodium sulfate, 45 parts of corn starch, 1.8 parts of β-diethylaminoethyl chloride hydrochloride, 78 parts of water.

[0017] The preparation method of above-mentioned pulp reinforcing agent is:

[0018] Weigh the ingredients according to the above ratio; add NaOH and sodium sulfate to the water, add cornstarch after dissolving and stir evenly, slowly add the aqueous solution of β-diethylaminoethyl chloride hydrochloride hydrochloride to the above solution, and keep stirring After 24 hours, the pH value was adjusted to 3 with hydrochloric acid, and finally filtered, washed and dried to obtain the product.

Embodiment 2

[0020] A paper pulp reinforcing agent is composed of the following ingredients in parts by weight: 1.5 parts of NaOH, 20 parts of sodium sulfate, 40 parts of cornstarch, 1.5 parts of β-diethylaminoethyl chloride hydrochloride and 75 parts of water.

[0021] The preparation method is the same as in Example 1.

Abstract

The invention discloses a paper pulp fortifier and a preparing method thereof. A sizing agent comprises, by weight, 1.5-2.0 parts of sodium hydroxide, 20-25 parts of sodium sulfate, 40-50 parts of corn starch, 1.5-2.0 parts of Beta-diethyl amidogen ethyl chloride hydrochloride, and 75-80 parts of water. The paper pulp fortifier has the advantages of being simple in ingredients, simple in the preparing method, good in use effects, harmless to human bodies, safe reliable, and meanwhile, capable of obviously improving tensile strength of paper.

Description

technical field [0001] The invention relates to a pulp reinforcing agent, in particular to a pulp reinforcing agent and a preparation method thereof, belonging to the field of pulp reinforcing agents. Background technique [0002] The strength properties of paper, including tensile strength, tear strength, and burst strength, are important parameters to measure the quality of paper. Generally, industrial paper and household paper require paper to have a certain strength. The most important factor affecting the strength of paper is fiber bonding (including hydrogen bonding, chemical bonding, polar bond attraction, and surface interweaving). Paper has a layered structure, the fibers in the plane are arranged in disorder, interlaced with each other, and mainly in two-dimensional orientation. The bonding between layers mainly depends on intermolecular forces and hydrogen bonds, but the number of interaction points is much smaller than that in layers. In the plane of the paper, ...
