Halogin-free harshen retardant dabara dabara don acrylic tushen ruwa adhesives

A cikin tsarin acrylic na tushen ruwa, ƙarin adadin aluminum hypophosphite (AHP) da zinc borate (ZB) yakamata a ƙayyade bisa takamaiman buƙatun aikace-aikacen (kamar ƙimar jinkirin wuta, kauri mai kauri, buƙatun aikin jiki, da sauransu) da tasirin haɗin gwiwa. A ƙasa akwai shawarwari na gabaɗaya da jeri na tunani:

II. Inganta Haɗin Rabo

1. Matsakaicin Haɗin Haɗin Kai:

• AHP:ZB = 2:1 ~ 4:1(misali, 15% AHP + 5% ZB, jimlar 20%).
• Daidaita rabo ta gwaji, misali:
• Bukatar jinkirin harshen wuta:AHP 15% ~ 20%, ZB 5% ~ 8%.
• Madaidaitan kaddarorin jiki:AHP 10% ~ 15%, ZB 3% ~ 5%.

1. Tasirin Haɗin Kai:

• Zinc borate yana inganta jinkirin wuta ta:
• Ƙarfafa haɓakar char (mu'amala da aluminum phosphate wanda AHP ya haifar).
• Sakin ruwa mai ɗaure don ɗaukar zafi da narke iskar gas mai ƙonewa.

III. Matakan Tabbatar da Gwaji

1. Gwajin Mataki Na Mataki:

• Gwajin mutum ɗaya:Da farko kimanta AHP (5% ~ 20%) ko ZB (5% ~ 15%) daban don jinkirin harshen wuta (UL-94, LOI) da aikin shafi (manne, taurin, juriya na ruwa).
• Haɓaka mahaɗa:Bayan zabar adadin AHP na asali, ƙara ZB (misali, 3% zuwa 8% lokacin da AHP ke 15%) kuma lura da haɓakawa a cikin jinkirin harshen wuta da illa.

1. Maɓalli Masu Nuna Ayyuka:

• Dagewar harshen wuta:LOI (manufa ≥28%), UL-94 rating (V-0/V-1), yawan hayaki.
• Kaddarorin jiki:Samuwar fim, mannewa (ASTM D3359), juriya na ruwa (babu delamination bayan nutsewar 48h).

IV. Mahimmin La'akari

• Kwanciyar Watsewa:
• AHP hygroscopic ne - pre-bushe ko amfani da bambance-bambancen da aka gyara.
• Yi amfani da masu rarrabawa (misali, BYK-190, TEGO Dispers 750W) don inganta daidaituwa da hana lalata.
• Daidaita pH:
• Tsarin acrylic na tushen ruwa yawanci suna da pH na 8-9; tabbatar da AHP da ZB sun kasance masu ƙarfi (kauce wa hydrolysis ko lalata).
• Yarda da Ka'ida:
• Dole ne AHP ya cika buƙatun RoHS marasa halogen; ZB yakamata yayi amfani da ƙananan ma'aunin ƙazanta mai nauyi-karfe.

V. Madadin ko Ƙarin Magani

• Melamine Polyphosphate (MPP):Zai iya ƙara haɓaka jinkirin harshen wuta lokacin da aka haɗa shi da AHP (misali, 10% AHP + 5% MPP + 3% ZB).
• Nano Flame Retardants:Nano-grade ZB (ƙari an rage zuwa 1% ~ 3%) ko Layered double hydroxides (LDH) don ingantattun tasirin shinge.

VI. Takaitacciyar Shawarwari

• Fara tsari:AHP 10% ~ 15% + ZB 3% ~ 5% (jimlar 13% ~ 20%), sannan ingantawa.
• Hanyar tabbatarwa:Gwada ƙananan samfurori don LOI da UL-94 yayin da ake kimanta kaddarorin inji.
