Cov tshuaj tiv thaiv hluav taws rau cov thermoplastic elastomer TPE

Thaum siv txhuas hypophosphite (AHP) thiab melamine cyanurate (MCA) hauv thermoplastic elastomers (TPE) kom ua tiav qhov ntsuas hluav taws kub UL94 V0, nws yog ib qho tseem ceeb uas yuav tsum xav txog lub tshuab hluav taws kub, kev sib raug zoo ntawm cov khoom siv, thiab cov xwm txheej ua tiav. Hauv qab no yog cov qauv pom zoo:

1. Kev Thauj Khoom Ib Txwm Muaj Thaum Siv Ib Leeg

Aluminium Hypophosphite (AHP)

• Thauj khoom: 15-25%
• Cov yam ntxwv: Txhawb kev tsim cov char, tsim nyog rau cov kab ke uas xav tau kev ua haujlwm siab, tab sis yuav tsum tswj qhov kub ntawm kev ua haujlwm (pom zoo ≤240 ° C).

Melamine Cyanurate (MCA)

• Thauj khoom: 25-35%
• Cov yam ntxwv: Cia siab rau kev rhuav tshem endothermic thiab roj dilution; kev thauj khoom ntau dhau yuav txo qhov yooj ntawm cov khoom.

2. Cov Qauv Sib Xyaws Sib Xyaws Pom Zoo

Qhov sib piv ntawm AHP thiab MCA

• AHP: 10-15%
• MCA: 10-20%
• Tag nrho cov khoom thauj: 20-30%

Cov txiaj ntsig: Cov nyhuv synergistic txo tag nrho cov load thaum txo qhov cuam tshuam rau cov khoom siv kho tshuab (piv txwv li, lub zog tensile, elasticity).

3. Cov Yam Tseem Ceeb Uas Cuam Tshuam

• Hom Khoom Siv Hauv Paus: Cov TPEs uas ua los ntawm SEBS feem ntau yooj yim dua rau kev tiv thaiv hluav taws dua li cov TPEs uas ua los ntawm SBS, uas ua rau muaj kev thauj khoom ntxiv tsawg dua me ntsis.
• Qauv tuabUL94 V0 ua raws li qhov tuab (1.6 hli nyuaj dua li 3.2 hli), yog li cov qauv yuav tsum tau hloov kho raws li qhov ntawd.
• Cov neeg sib koom tesNtxiv 2-5% nano-clay lossis talc tuaj yeem ua rau cov char tsim tau zoo dua thiab txo cov khoom siv tiv thaiv hluav taws.
• Kub Ua HaujlwmXyuas kom qhov kub ntawm kev ua cov khoom tseem nyob hauv qab cov ntsiab lus lwj ntawm AHP (≤240°C) thiab MCA (≤300°C).

4. Cov Kauj Ruam Txheeb Xyuas Pom Zoo

• Kev Ntsuas Ua NtejUa cov kev sim me me nrog AHP 12% + MCA 15% (tag nrho 27%).
• Kev Ntsuas Kev Ua HaujlwmTshuaj xyuas qhov tsis kam hluav taws (UL94 vertical burning), hardness (Shore A), tensile strength, thiab melt flow index.
• Kev Txhim KhoYog tias muaj dej ntws, nce AHP piv (kom txhim kho kev kub hnyiab); yog tias cov khoom siv kho tshuab tsis zoo, xav txog kev ntxiv cov khoom yas lossis txo tag nrho cov khoom thauj.

5. Kev ceev faj

• Tsis txhob sib xyaw nrog cov khoom siv acidic (piv txwv li, qee cov xim), vim tias lawv yuav ua rau AHP tsis ruaj khov.
• Yog tias TPE muaj cov roj ntau ntau uas ua rau cov yas puas, tej zaum yuav tsum tau nce qhov kev thauj khoom uas tiv taus hluav taws (roj tuaj yeem txo qhov ua tau zoo ntawm kev tiv taus hluav taws).

Los ntawm kev sib xyaw ua ke thiab kev sim ua kom zoo, UL94 V0 ua raws li qhov yuav tsum tau ua thaum sib npaug ntawm TPE cov txheej txheem ua haujlwm thiab kev ua haujlwm ntawm lub tshuab. Kev koom tes nrog cov neeg muab khoom tiv thaiv hluav taws rau cov kev daws teeb meem tshwj xeeb yog qhov pom zoo.
