Nplaim retardant kev daws teeb meem rau thermoplastic elastomer TPE

Nplaim retardant kev daws teeb meem rau thermoplastic elastomer TPE

Thaum siv aluminium hypophosphite (AHP) thiab melamine cyanurate (MCA) hauv cov thermoplastic elastomers (TPE) kom ua tiav qhov ntsuas UL94 V0 nplaim hluav taws, nws yog qhov tseem ceeb uas yuav tsum xav txog cov nplaim hluav taws xob, cov khoom siv sib xws, thiab kev ua haujlwm. Hauv qab no yog cov formulation pom zoo:

1. Kev thauj khoom ib txwm siv thaum siv tus kheej

Aluminium Hypophosphite (AHP)

• Chaw thau khoom: 15-25%
• Yam ntxwv: Txhawb kev tsim char, haum rau cov tshuab uas xav tau kev ua haujlwm siab, tab sis kev ua haujlwm kub yuav tsum tswj tau (pom zoo ≤240 ° C).

Melamine Cyanurate (MCA)

• Chaw thau khoom: 25-35%
• Yam ntxwv: Relies on endothermic decomposition thiab gas dilution; kev thauj khoom siab tuaj yeem txo cov khoom siv tau yooj yim.

2. Pom zoo Synergistic Blending Formula

AHP thiab MCA Blending Ratio

• PIB: 10-15%
• MCA: 10-20%
• Tag nrho loading: 20-30%

Qhov zoo: Synergistic nyhuv txo tag nrho cov loading thaum txo qhov cuam tshuam rau txhua yam khoom (xws li, tensile zog, elasticity).

3. Yam tseem ceeb cuam tshuam

• Base Khoom hom: SEBS-raws li TPEs yog feem ntau yooj yim rau nplaim-retard dua SBS-based sawv daws yuav, tso cai rau me ntsis ntxiv ntxiv loading.
• Qauv Thickness: UL94 V0 ua raws li cov thickness-sensitive (1.6mm yog qhov nyuaj tshaj 3.2mm), yog li cov formulations yuav tsum tau kho raws li.
• Synergists: Ntxiv 2-5% nano-av nplaum los yog talc tuaj yeem txhim kho char tsim thiab txo cov nplaim retardant loading.
• Ua Haujlwm Kub: Xyuas kom cov txheej txheem kub nyob hauv qab cov ntsiab lus decomposition ntawm AHP (≤240 ° C) thiab MCA (≤300 ° C).

4. Cov kauj ruam pov thawj pom zoo

• Kev Xeem Ua Ntej: Ua kev sim me me nrog AHP 12% + MCA 15% (tag nrho 27%).
• Kev Ntsuas Kev Ua Haujlwm: Ntsuas cov nplaim hluav taws kub (UL94 ntsug kub), hardness (Shore A), lub zog tensile, thiab yaj ntws ntsuas.
• Kev ua kom zoo: Yog tias dripping tshwm sim, nce AHP piv (kom txhim kho charring); Yog tias cov khoom siv tshuab tsis zoo, xav txog kev ntxiv cov yas yas lossis txo cov khoom thauj tag nrho.

5. Ceev faj

• Tsis txhob sib xyaw nrog acidic fillers (xws li, qee yam xim), vim tias lawv tuaj yeem ua rau AHP tsis muaj zog.
• Yog tias TPE muaj cov khoom siv roj ntau ntau, cov nplaim hluav taws xob yuav tsum tau nce ntxiv (roj tuaj yeem txo cov nplaim hluav taws xob ua haujlwm).

Los ntawm kev sib xyaw ua ke thiab kev sim ua kom zoo, UL94 V0 kev ua raws cai tuaj yeem ua tiav thaum ntsuas TPE kev ua haujlwm thiab kev ua haujlwm txhua yam. Kev koom tes nrog cov khoom siv hluav taws xob hluav taws xob rau cov kev daws teeb meem raug pom zoo.
