Flame retardant mhinduro ye thermoplastic elastomer TPE

Flame retardant mhinduro ye thermoplastic elastomer TPE

Paunenge uchishandisa aluminium hypophosphite (AHP) uye melamine cyanurate (MCA) mune thermoplastic elastomers (TPE) kuti uwane UL94 V0-inodzoreredza mwero wemoto, zvakakosha kuti titarise nzira inodzoreredza moto, kuenderana kwezvinhu, uye kugadzirisa mamiriro. Pazasi pane inokurudzirwa kugadzirwa:

1. Typical Loading Kana Inoshandiswa Iga

Aluminium Hypophosphite (AHP)

• Kutakura: 15-25%
• Hunhu: Inosimudzira kuumbwa kwechar, yakakodzera kune masisitimu anoda yakakwira mechanical kuita, asi kugadzirisa tembiricha kunofanirwa kudzorwa (inokurudzirwa ≤240 ° C).

Melamine Cyanrate (MCA)

• Kutakura: 25-35%
• Hunhu: Inotsamira pakuora endothermic uye dilution gasi; kukwidza zvakanyanya kunogona kuderedza kushanduka kwezvinhu.

2. Yakakurudzirwa Synergistic Blending Formula

AHP uye MCA Blending Ratio

• AHP: 10-15%
• MCA: 10-20%
• Yese kurodha: 20-30%

Zvakanakira: Synergistic mhedzisiro inoderedza kurodha kwakazara uku ichideredza kukanganiswa kwezvinhu zvemuchina (semuenzaniso, kusimba kwesimba, elasticity).

3. Zvinhu Zvikuru Zvinokurudzira

• Base Material Type: SEBS-based TPEs kazhinji iri nyore kudzima-murazvo pane SBS-based, zvichibvumira kuderera zvishoma kwekuwedzera kurodha.
• Muenzaniso Ukobvu: UL94 V0 kutevedzera ukobvu-kunzwa (1.6mm inonetsa kupfuura 3.2mm), saka magadzirirwo anofanirwa kugadziridzwa zvinoenderana.
• Synergists: Kuwedzera 2-5% nano-ivhu kana talc inogona kuwedzera char kuumbwa uye kuderedza moto unodzora kurodha.
• Processing Temperature: Ita shuwa kuti tembiricha yekugadzira inoramba iri pasi peiyo decomposition point yeAHP (≤240 ° C) uye MCA (≤300 ° C).

4. Yakakurudzirwa Verification Matanho

• Preliminary Testing: Ita zviedzo zvidiki neAHP 12% + MCA 15% (yakazara 27%).
• Performance Testing: Ongorora flame retardancy (UL94 vertical burning), kuoma (Shore A), tensile simba, uye melt flow index.
• Optimization: Kana kudonha kukaitika, wedzera AHP chiyero (kuwedzera charring); kana michina miitiro yakashata, funga kuwedzera plasticizers kana kuderedza kuzara kurodha.

5. Chengetedzo

• Regedza kusanganisa nema acidic fillers (semuenzaniso, mamwe mavara), sezvo anogona kukanganisa AHP.
• Kana iyo TPE iine huwandu hwakakura hwemafuta-based plasticizers, murazvo unoregedzesa kurodha ungangoda kuwedzerwa (mafuta anogona kudzikisa murazvo retardancy kunyatsoita).

Kuburikidza nekubatanidza zvine musoro uye kuyedza optimization, UL94 V0 kutevedzera kunogona kuwanikwa uku uchienzanisa TPE processability uye mechanic performance. Kudyidzana nevashambadziri vemoto retardant kune zvakagadziridzwa mhinduro kunokurudzirwa.
