Abstract

The invention provides a chain extender composition used for recycling nylon and a preparation method thereof. The main components of the chain extender composition comprise an epoxy functionalized chain extender and an acidic absorbent. The preparation method of the chain extender composition comprises: uniformly mixing the chain extender with the acidic absorbent in a high speed agitator under room temperature. Compared with the existing pure chain extender modified nylon recycling technology, the chain extender composition disclosed by the invention has the beneficial effects of improving the efficiency of the chain extender and recycling the modification cost of recycled nylon.

Description

A kind of for reclaiming chain extender composition of nylon and preparation method thereof
Technical field
The present invention relates to a kind ofly for reclaiming chain extender composition of nylon and preparation method thereof, belong to nylon auxiliary agent technical field.
Background technology
Chainextender is the class New-type adjuvant that current modified plastic industry occurs, makes the molecular weight of macromole generation coupling or branching reaction raising polymkeric substance by the polyfunctional compound of Heat stability is good.Chain extending reaction completes with reactive extrusion technology conventionally, has the advantages such as easy, quick, safe, enhances product performance, and can improve the quality of material, thereby improve the competitive power of modified plastics product.Reclaim in nylon and add the melt flow that chainextender can relax recovery nylon, the modulus intensity of lifting recovery nylon is toughness even, promotes the resistant to hydrolysis performance that reclaims nylon, and significantly the physicals of improving product makes its performance that reaches virgin material or be better than virgin material.But in recovery nylon, contain a large amount of fire retardants, it can discharge alkaline matter in the course of processing, affects greatly the effect of chainextender.
Summary of the invention
In order to overcome the defect that above-mentioned prior art the exists a kind of technique providing chain extender composition simple, easy to use, with low cost and preparation method thereof is provided.
For reclaiming a chain extender composition for nylon, this chain extender composition main ingredient comprises chainextender and the acid absorption agent of epoxy-functional.
The chainextender mass percent of the epoxy-functional described in this chain extender composition is 4 0-60%, and all the other compositions are acid absorption agent.
Described epoxy-functional chainextender is KL-E4370.
Described acid absorption agent or be zinc chloride, or be calcium chloride, or be calcium sulfate, or be the mixture of zinc chloride, calcium chloride, calcium sulfate.
A kind of preparation method with reclaiming Buddhist nun's chain extender composition: will mix and make in high speed agitator under the chainextender of epoxy-functional and acid absorption agent room temperature.
Compare with existing simple use chainextender technology, feature of the present invention is that with low cost, modified effect is obvious; Acid absorption agent composition in chainextender combination provided by the invention, can adsorb in the course of processing and reclaim the alkaline matter that nylon discharges, and has improved the chain extension effect of chainextender, and the course of processing is stable, has improved production efficiency and yield rate.
Embodiment
Below in conjunction with specific examples, the present invention will be further described in detail.
Example 1

Example 3
Add mixing discharging in 3 ~ 5 minutes in GX-10B 500g multifunctional crusher (Zhejiang Gao Xin Trade Co., Ltd.) to obtain chain extender composition in the calcium chloride of the KL-E4370 of 80g and 120g.
Example 4
Add mixing discharging in 3 ~ 5 minutes in GX-10B 500g multifunctional crusher (Zhejiang Gao Xin Trade Co., Ltd.) to obtain chain extender composition the zinc chloride of the KL-E4370 of 100g and 100g.
Example 5
Add mixing discharging in 3 ~ 5 minutes in GX-10B 500g multifunctional crusher (Zhejiang Gao Xin Trade Co., Ltd.) to obtain chain extender composition in the calcium sulfate of the KL-E4370 of 100g and 100g.
Example 6
The mixture of the KL-E4370 of 100g and 30g zinc chloride, 30g calcium chloride, 40g calcium sulfate is added and in GX-10B 500g multifunctional crusher (Zhejiang Gao Xin Trade Co., Ltd.), mixes discharging in 3 ~ 5 minutes and obtain chain extender composition.
Example 7
Performance test
Before blend, reclaim nylon dry 4h at 100 ℃.Dried recovery nylon is put into plastics bag and is added 0.1% whiteruss and mix, and then adds 2% chain extender composition to mix.Mixture is added in the homodromal twin screw extruder of SHJ (Nanjing Jieya Extruding Equipment Co., Ltd.), length-to-diameter ratio 40, main frame frequency is determined, from charging opening to head, the temperature in each district is respectively 210/225/235/240/240/235/230 ℃, extrude, water cooling bracing, granulation, dry.Reclaim the melting index of nylon and measured by SRZ-400D type liquid-crystal display melt flow rate (MFR) determinator (Zhejiang Univ), counterweight is 2.16kg, 230 ℃ of temperature.
Experimental result:
Sample Melting index is
Embodiment 1 2.28 g/10min
Embodiment 2 2.32 g/10min
Embodiment 3 2.16 g/10min
Embodiment 4 2.25 g/10min
Embodiment 5 2.30 g/10min
Embodiment 6 2.19 g/10min
Contrast sample (pure chainextender) 2.90 g/10min
Experimental result shows: chain extender composition chain extension provided by the invention is respond well, can make the nylon course of processing stable, has improved production efficiency and yield rate.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
