The synthesis method comprises the following steps: reacting chloroacetic acid and a polyacrylamide aqueous solution for 30 to 50 minutes at the temperature of 50 to 60 DEG C; then, adding sodium hydroxide into the reactant, and reacting for 30 to 50 minutes at the temperature of 50 to 60 DEG C to obtain a polyacrylamide fabric softener; regulating the pH value of the polyacrylamide fabric softener to be 6 to 8 at the temperature of 50 to 60 DEG C; and cooling, and adding emulsified silicone oil into the polyacrylamide fabric softener of which the pH value is regulated and mixing uniformly to obtain the inorganic fabric softener. According to the synthesis method for the inorganic fiber softener, the utilization rate of the inorganic fiber softener can be increased; the paper softness is remarkably improved by processing the inorganic fibers by adopting the inorganic fiber softener obtained by the method and then performing papermaking, and the synthesis method has the characteristics of being simple to operate and easy to implement.
Description
Technical field
The invention belongs to inorfil softening agent synthesis field, more particularly to a kind of synthesis side of inorfil softening agent
Method.
Background technology
With the continuous development of society, the demand field of paper is more and more wider, people to the demand of paper also increasingly
Greatly.And traditional Plant fiber's papermaking does not only exist the problems such as Forest resources dynamics are big, environmental pollution is more serious, while receiving papermaking
The restriction of raw material, institute into paper there is easy firing, the easy moisture absorption to go mouldy the features such as, constrain traditional plant fibrous paper each
The application and development of each industry of row.Inorfil have do not fire, the characteristics of not burnt, anti-mildew becomes, the appearance of specialty inorganic fibrous paper is fitted
When advance the further development of paper industry.
It is many using inorfil papermaking advantage, but there is also some shortcomings.First, inorfil is unable to fibrillating,
Fragility is big, and rigidity is strong, and fiber is short, and Jing beating, dispersion in pulping process, conveying is easier to rupture.Second, most inorganic fibres
Dimension difficulties in dispersion, the problems such as easily there is segment fiber interweaving, occluding device, papermaking difficulty is big.Third, being copied into inorfil
Paper paper surface is rougher, and easy dry linting, pliability is poor, and unsuitable folding, poor using feel, comfort level is not good enough.These are not
Foot greatly have impact on application and development of the inorganic fibre paper in productive life, therefore must be from suitable dispersant and softening agent
Inorfil is processed, with reinforcing fiber pliability, its ru nnability is improved.
The content of the invention
It is an object of the invention to provide a kind of synthetic method of inorfil softening agent, it is possible to increase the profit of inorfil
Inorfil is processed with rate, and the inorfil softening agent obtained using the method, then carries out papermaking, its paper pliability
Be significantly improved, with it is simple to operate, easy to implement the characteristics of.
In order to achieve the above object, the technical solution used in the present invention is comprised the following steps：
1) monoxone and polyacrylamide solution are reacted into 30-50min at 50-60 DEG C, is then added thereto to hydrogen
Sodium oxide, and 30-50min is reacted at 50-60 DEG C, obtain polyacrylamide fibers softening agent；Wherein, monoxone and polypropylene
The mass ratio of polyacrylamide is 1 in amide aqueous solution：(1.5-2), sodium hydroxide and polypropylene in polyacrylamide solution
The mass ratio of amide is 1：(5-6)；
2) pH value of polyacrylamide fibers softening agent is adjusted to into 6-8 at 50-60 DEG C, is then lowered the temperature, to regulation pH
Emulsified silicone oil mix homogeneously is added in polyacrylamide fibers softening agent after value, inorfil softening agent is obtained；Wherein, adjust
The mass ratio of polyacrylamide fibers softening agent and emulsified silicone oil after pH refers to is 1：(0.5-1).
Described step 1) in polyacrylamide solution be according to 1：(60-80) mass ratio is by polyacrylamide and water
Mix what is obtained at 45-50 DEG C.
Described step 2) in emulsified silicone oil be emulsifying dimethicone.
Described step 2) in be cooled to less than 40 DEG C.
Compared with prior art, beneficial effects of the present invention are：
The aqueous solution and monoxone that present invention employs the polyacrylamide with stronger fiber evacuation capacity carries out acid
Change reaction, make the amino on polyacrylamide be converted into ammonium ion and become positively charged, make the inorfil softening agent for finally giving
Can be easy to absorption on electronegative inorfil, fiber is effectively softened；Meanwhile, polyacrylamide per se with
Certain can electrically strengthen its interaction between inorfil；And add on solid sodium hydroxide, with acrylamide
Carboxyl is neutralized reaction, generates negatively charged carboxylate radical, so as to get the inorfil that processed of inorfil softening agent it is fine
Dispersion, do not reunite；Therefore, the obtained inorfil softening agent of the present invention is processed inorfil, the inorganic fibre of gained
Dimension pliability is significantly improved, what the inorfil that the Jing used in the paper-making process inorfil softening agent was processed was manufactured paper with pulp
Paper performance is improved, with it is simple to operate, easy to implement the characteristics of.
In addition, being also added into reducing mutual frictional force between inorfil in the inorfil softening agent prepared by the present invention
Emulsified silicone oil, so that inorfil feel is more smooth.Inorfil Jing after above-mentioned two-step pretreatment mixes with Plant fiber to be made
Paper, its paper pliability is significantly improved.
