Description
Technical field:
The present invention relates to regenerated terylene silk processing technique fields, and in particular to a kind of to process Gao Mo using Pillar recovery bottle piece
The technics of enhancing viscosity of low-shrinkage dacron thread.
Background technique:
It is the main path of the current polyester recycling and reusing in China using waste polyester bottle chip production regenerated fiber, however this
A little fibers are mainly the cotton of some low sides, filled-type product, since the expansion and homogeneity of production capacity are serious, regenerated fiber enterprise
Industry is in meagre profit state.Therefore high-endization of regenerated fiber, functionality just seem necessary.
Requirement of the HMLS Polyester silk to raw material is not achieved in the intrinsic viscosity (about 0.6dL/g) of common PET slice, and passes through
The PET melt intrinsic viscosity of PET bottle piece recycling is lower.Therefore, it in order to improve the intrinsic viscosity of PET melt, needs to recycled PET
Carry out tackified finish.At present frequently with thickening mode be PET chain extension thickening, but the Efficient Adhesive Promotion of this thickening mode is limited,
And ensuring tackifier be added will not decompose reaction during high temperature extrusion molding, otherwise will affect recycling
The recycling property energy of PET.
Summary of the invention:
Technical problem to be solved by the present invention lies in one kind is provided, operation is simple, process control parameter is clear and work
The reproducible technics of enhancing viscosity using Pillar recovery bottle piece processing HMLS Polyester silk of skill.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
Utilize the technics of enhancing viscosity of Pillar recovery bottle piece processing HMLS Polyester silk, comprising the following steps:
(1) it crushes: first waste polyester bottle chip being transferred in freezing chamber and is stood, is produced after chilled processing, and through pulverizer
The particle of 1~5mm of granularity is made to get waste and old polyester particle；
(2) it cleans: gained waste and old polyester particle is sent into rotary drum washer, spray cleaning in rotary drum washer
Liquid is cleaned at 300~500rpm of revolving speed, and cleaning solution is discharged after cleaning, then draws off waste and old polyester particle；
(3) it dries: once purged polyester granulate being sent into roller dryer, and at 200~400rpm of revolving speed
Water content is dried to lower than 0.5wt%；
(4) it viscosifies: tackifier being added into polyester granulate after drying, and uniform in stirrer for mixing, enter back into
Extruder carries out extrusion plasticizing, and the heating temperature in extruder is 250~260 DEG C；
(5) die head exports: the material after plasticizing is sent into die head through runner, exports sheet material through die head, and runner temperature 250~
260 DEG C, 260~270 DEG C of die head temperature.
Cryogenic temperature is 5~10 DEG C in the step (1).
The freezing processing time is 8~12h in the step (1).
Cleaning solution temperature is 45~55 DEG C in the step (2).
Scavenging period is 10~30min in the step (2).
Drying temperature is 65~75 DEG C in the step (3).
The weight ratio of polyester granulate and tackifier is 100:5~15 in the step (4).
Tackifier are pyromellitic acid anhydride in the step (4).The pyromellitic acid anhydride pair during extrusion plasticizing
PET carries out chain extension thickening, belongs to chemical thickening mode.
Trihydroxymethylpropanyltri diglycidyl ether of the tackifier by weight ratio 2:1:0.5, poly- two season penta in the step (4)
Six acrylate of tetrol and stearyl alcohol glycyrrhetin acid esters composition.The tackifier are punctured into PET molecule knot during extrusion plasticizing
In structure, belong to physics thickening mode.
Cleaning solution is dissolved in water by cleaning agent and is made in the step (2).
The cleaning agent is decyl glucoside, and dosage is that every 1kg water dissolves 0.5~5g decyl glucoside.
The cleaning agent is decyl glucoside-pyroglutamic acid carboxylate, and dosage is that every 1kg water dissolves 0.5~5g decyl
Glucoside-pyroglutamic acid carboxylate.
The decyl glucoside-pyroglutamic acid carboxylate is made of decyl glucoside, pyroglutamic acid through esterification,
Preparation method are as follows: first decyl glucoside and pyroglutamic acid are dissolved in the water respectively, are configured to decyl glucoside solution
With pyroglutamic acid solution, then the concentrated sulfuric acid is added dropwise into pyroglutamic acid solution and adjusts solution ph to 3~4, decyl Portugal is then added dropwise
Polyglycoside solution is warming up to reflux state insulation reaction after being added dropwise, after reaction be concentrated under reduced pressure be made solid content 65~
75% lotion, gained lotion are sent into freeze drier after cooled to room temperature, and dry obtained solid is through pulverizing
15~20 μm of granularity of micro mist is made to get decyl glucoside-pyroglutamic acid carboxylate in machine.
The decyl glucoside and the molar ratio of pyroglutamic acid are 1:5.
The beneficial effects of the present invention are:
(1) present invention improves the brittleness of waste polyester bottle chip by freezing processing, in favor of guaranteeing grinding particle size
On the basis of improve crush efficiency, reduce pulverizer energy consumption；And using first crush clean afterwards by the way of can significantly improve cleaning
Efficiency, the dust and greasy dirt washed down are easier to enter in cleaning waste water；
(2) present invention efficiently removes the dust and greasy dirt that adhere on waste and old polyester particle by cleaning operation, avoids ash
The presence of dirt and greasy dirt influences the regeneration of waste and old polyester particle, and mitigates cleaning institute by selecting environmental type cleaning agent
Generate the processing difficulty of waste water；
(3) present invention carries out tackified finish to waste and old polyester by two kinds of thickening modes, make after processing gained PET it is molten
The intrinsic viscosity of body significantly increases, to meet requirement of the HMLS Polyester silk to raw material.
