Description
Technical field：
The present invention relates to paper-making industry field, and in particular to a kind of preparation method of paper mould slurries.
Background technology：
Paper mould is a kind of three-dimensional paper technology.It is moulded using waste paper as raw material on mould machine by certain moduli tool
Go out the paper products of definite shape.Moulded paper pulp product is new packaging material swift and violent in recent years, is the excellent substitute of timber.
It has four big advantages：Raw material is waste paper, including paperboard, litter decoration paper, useless white edge paper etc., wide material sources；Its manufacturing process by
The processes such as slurrying, adsorption forming, dryness finalization are completed, environmental sound；Can be with recovery and reusing and recycling；Volume ratio foamed plastic
It is small, can be overlapping, communications and transportation is convenient.Paper mould, it is more to do industrial buffering package in addition to cutlery box, tableware is made, develop ten at present
Divide rapid.
The content of the invention：
It is an object of the present invention to provide a kind of preparation method of paper mould slurries.
Technical scheme is as follows：
A kind of preparation method of paper mould slurries, comprises the following steps：
A, get the raw materials ready：Take the straw of 30-35 parts by weight, the boll hull of 20-30 parts by weight, the sugarcane of 10-15 parts by weight
Slag, the cornstalk of 5-10 parts by weight, the bamboo of 15-20 parts by weight, the tealeaves bar of 6-12 parts by weight is standby；
B, immersion：Starting material with water in step a is rinsed, is soaked in water 10-15 minutes, impurity is filtered off, 20 weight are added
The acetic acid of number, is then heated to 60-80 degree, continues to soak 15-20 minutes；
C, boiling：The step b raw material handled well are filtered out, are put into boiling vessel, the lime of 15-20 parts by weight is added
Water, carries out boiling；
D, pulping：The digested starting material with water power pulpers of step c are crushed, peptizaiton is played to paper pulp；
E, discongest：The slurry that step d is handled well is discongested with difunctional fluffer, by the cut-out of fluffer, is divided
Silk, fibrillating, can make finished fabric slurry made of paper uniform, improve the evenness of chemical assistant, increase the intensity of finished product, can also remove
Dirt；
F, addition auxiliary agent：The paper pulp that step e has been discongested adds chemical assistant；
G, homogenate：The slurry that step f is handled well is disperseed with agitator, is homogenized；
H, the paper pulp for handling step g well carry out Top wire former.
Further, cooking pressure is 5-10kg/cm in the digestion process of the step c2, boiling temperature is 80-120
Degree, digestion time is 30-50 minutes.
Further, the chemical assistant of the step f includes polyethyleneimine, the urine of 3 parts by weight of 5 parts by weight
Element, the paraffin latex of the ammonium sulfate of 1.8 parts by weight, the sodium hydroxide of 4 parts by weight, 1.3 parts by weight, 5 parts by weight
Activated carbon.
Further, the agitator mixing speed of the step g is 30~60 revs/min.
Further, the step d carries out pulp washing with being additionally provided with after pulper pulping with the machine of washing drum, to improve paper
The quality of slurry.
Further, concentration pulper during the hydrabrusher of the step d is selected, in dense pulping when can shorten mashing
Between, reduction energy consumption, the utilization rate for improving equipment, reduction production cost, and the quality of slurries can also be improved, be conducive to forming machine
Manufacture paper with pulp.
Beneficial effects of the present invention：
1st, the paper mould slurries quality that is produced of the present invention is high, and stability is good, using natural raw material, crops,
Plant waste makes, more environmentally friendly more par；
2nd, raw material are carried out before pulping making, first raw material is cleaned, soaked, the impurity in raw material removed, energy
Enough ensure the quality of finished product, add acetic acid and carry out heating immersion, raw material is softened, remove impurity, be easy to follow-up pulping to grasp
Make；
3rd, before pulping, boiling step is also added into, and adds limewash progress boiling, immersion process is on the one hand neutralized
Middle acetate component, it is to avoid acetic acid residual produces influence to follow-up operation, moreover it is possible to sterilization, desinsection are played to raw material, decolourizes, make original
Expect that structure is looser, paper pulp is formed to be more easily dispersed in handling process afterwards in water.
4th, a small amount of paraffin latex is added in chemical reagent, by increasing capacitance it is possible to increase the sticky shape and concentration of paper pulp, added
Activated carbon, can adsorb chemical gas unpleasant in paper pulp, make paper pulp smell more preferably, more environmentally friendly；
5th, agitator mixing speed is set to 30~60 revs/min, can play scattered, homogenate effect, height is avoided that again
The reagent and additive in polymerization of molecular weight is acted on by the high speed shear of agitator, is destroyed its long chain, is made the effect of chemical assistant
By destroying, hydrolyze.
