Bii o ṣe le ṣe kanrinkan latex ti ina retardant?

Fun awọn ibeere idaduro ina ti sponge latex, atẹle jẹ itupalẹ ti o da lori ọpọlọpọ awọn idaduro ina ti o wa tẹlẹ (aluminiomu hydroxide, borate zinc, hypophosphite aluminiomu, MCA) pẹlu awọn iṣeduro agbekalẹ:

I. Onínọmbà ti Ohun elo Idaduro Ina ti o wa tẹlẹ

Aluminiomu Hydroxide (ATH)
Awọn anfani:

• Ore ayika, iye owo kekere.
• Ṣiṣẹ nipasẹ jijẹ endothermic ati itusilẹ oru omi, o dara fun awọn ọna ṣiṣe ti ko ni halogen.

Awọn alailanfani:

• Nilo ikojọpọ giga (30-50 phr) fun imunadoko, eyiti o le ni ipa rirọ kanrinkan ati iwuwo.

Ohun elo:

• Dara fun ipilẹ ina retardant formulations.
• Iṣeduro lati darapo pẹlu awọn amuṣiṣẹpọ (fun apẹẹrẹ, borate zinc).

Sinkii Borate
Awọn anfani:

• Idaduro ina amuṣiṣẹpọ, mu imudara ATH pọ si.
• Nse char Ibiyi ati ki o suppresses ẹfin.

Awọn alailanfani:

• Imudara to lopin nigba lilo nikan; nbeere apapo pẹlu miiran ina retardants.

Ohun elo:

• Ti ṣe iṣeduro bi amuṣiṣẹpọ fun ATH tabi aluminiomu hypophosphite.

Aluminiomu Hypophosphite
Awọn anfani:

• Ṣiṣẹ daradara, laisi halogen, ikojọpọ kekere (10-20 phr).
• Iduroṣinṣin igbona ti o dara, o dara fun awọn ibeere idaduro ina giga.

Awọn alailanfani:

• Iye owo ti o ga julọ.
• Ibamu pẹlu awọn ọna ṣiṣe latex nilo ijẹrisi.

Ohun elo:

• Dara fun awọn iṣedede idaduro ina giga (fun apẹẹrẹ, UL94 V-0).
• Le ṣee lo nikan tabi ni apapo.

MCA (Melamine Cyanurate)
Awọn anfani:

• Idaduro ina ti o da lori nitrogen, ti nmu ẹfin.

Awọn alailanfani:

• Iyapa ti ko dara.
• Le dabaru pẹlu foomu.
• Iwọn otutu jijẹ giga (~ 300°C), ti ko baamu pẹlu sisẹ latex iwọn otutu kekere.

Ohun elo:

• Ko ṣe iṣeduro bi ayo; nbeere esiperimenta afọwọsi.

II. Niyanju Fọọmù ati ilana Awọn didaba

Ilana 1: ATH + Zinc Borate (Aṣayan Aje)
Àkópọ̀:

• Aluminiomu Hydroxide (ATH): 30-40 phr
• Sinkii Borate: 5-10 phr
• Pipinka (fun apẹẹrẹ, aṣoju asopọ silane): 1-2 phr (ṣe itusilẹ dara si)

Awọn abuda:

• Iye owo kekere, ore ayika.
• Dara fun awọn ibeere idaduro ina gbogbogbo (fun apẹẹrẹ, UL94 HF-1).
• Le die-die din kanrinkan resilience; Ti o dara ju Vulcanization nilo.

Ilana 2: Aluminiomu Hypophosphite + Zinc Borate (Aṣayan Ṣiṣe-giga)
Àkópọ̀:

• Aluminiomu Hypophosphite: 15-20 phr
• Zinc Borate: 5-8 phr
• Pilasita (fun apẹẹrẹ, paraffin olomi): 2-3 phr (ṣe imudara ilana ṣiṣe)

Awọn abuda:

• Iṣeduro imuduro ina giga, ikojọpọ kekere.
• Dara fun awọn oju iṣẹlẹ eletan giga (fun apẹẹrẹ, ina inaro V-0).
• Ibamu ti aluminiomu hypophosphite pẹlu latex nilo idanwo.

Ilana 3: ATH + Aluminiomu Hypophosphite (Aṣayan Iwontunwọnsi)
Àkópọ̀:

• Aluminiomu Hydroxide: 20-30 phr
• Aluminiomu Hypophosphite: 10-15 phr
• Zinc Borate: 3-5 phr

Awọn abuda:

• Awọn iwọntunwọnsi iye owo ati iṣẹ.
• Dinku igbẹkẹle lori idaduro ina kan, idinku ipa lori awọn ohun-ini ti ara.

III. Awọn imọran ilana

Pipinpin:

• Awọn idaduro ina yẹ ki o wa ni ilẹ si ≤5μm lati yago fun ni ipa lori eto foomu.
• Pipin-tẹlẹ ni latex tabi ohun elo dapọ iyara giga ni a gbaniyanju.

Awọn ipo Itọju:

• Ṣakoso iwọn otutu imularada (ni deede 110-130 ° C fun latex) lati ṣe idiwọ ibajẹ ti tọjọ ti awọn idaduro ina.

Idanwo Iṣe:

• Awọn idanwo pataki: Atọka Atẹgun (LOI), Inaro Burn (UL94), iwuwo, Resilience.
• Ti idaduro ina ko ba to, maa pọ si hypophosphite aluminiomu tabi awọn ipin ATH.

IV. Afikun Awọn iṣeduro

Idanwo MCA:

• Ti o ba jẹ idanwo, lo 5-10 phr ni awọn ipele kekere lati ṣe akiyesi ipa lori isokan foaming.

Awọn iwe-ẹri Ayika:

• Rii daju pe awọn idaduro ina ti o yan ni ibamu pẹlu RoHS/REACH fun awọn okeere.

Awọn idapọmọra Amuṣiṣẹpọ:

• Gbero fifi awọn iwọn kekere ti nanoclay (2-3 phr) lati jẹki awọn ipa idena char.
