Iyo dhizaini inodzoreredza dhizaini yekunamira inoda kugadziridzwa zvichienderana neadhesive's base material type (senge epoxy resin, polyurethane, acrylic, nezvimwewo) uye mamiriro ekushandisa (sekuvaka, zvemagetsi, mota, nezvimwewo). Pazasi pane akajairika adhesive flame retardant ekugadzira zvinhu uye mabasa awo, anofukidza ese halogenated uye halogen-isina murazvo retardant mhinduro.
1. Nheyo dzeAdhesive Flame Retardant Formulation Design
- Kubudirira Kwepamusoro: Sangana neUL 94 V0 kana V2.
- Kugarisana: Iyo inodzoreredza murazvo inofanirwa kuenderana neyakanamatira base zvinhu pasina kukanganisa bonding performance.
- Ushamwari Hwakatipoteredza: Isa pamberi pehalogen-isina murazvo retardants kutevedzera mirairo yezvakatipoteredza.
- Processability: Iyo inodzoreredza murazvo haifanire kuvhiringa nzira yekunamatira yekurapa kana kuyerera.
2. Halogenated Flame Retardant Adhesive Formulation
Halogenated flame retardants (semuenzaniso, brominated) inovhiringidza kutsva kweketani nekuburitsa halogen radicals, ichipa yakanyanya kudzosa moto.
Magadzirirwo Zvikamu:
- Adhesive Base Material: Epoxy resin, polyurethane, kana acrylic.
- Brominated Flame Retardant: 10-20% (semuenzaniso, decabromodiphenyl ether, brominated polystyrene).
- Antimony Trioxide (Synergist): 3-5% (inowedzera murazvo unodzora mhedzisiro).
- Plasticizer: 1-3% (inovandudza kushanduka).
- Kurapa Agent: Yakasarudzwa zvichienderana nemhando yekunamatira (semuenzaniso, amine-yakavakirwa epoxy resin).
- Solvent: Sezvinodiwa (inogadzirisa viscosity).
Hunhu:
- Zvakanakira: High flame retardant performance, yakaderera yekuwedzera huwandu.
- Zvakaipa: Inogona kuburitsa magasi ane muchetura panguva yekupisa; zvinonetsa kwezvakatipoteredza.
3. Halogen-Free Flame Retardant Adhesive Formulation
Halogen-isina flame retardants (semuenzaniso, phosphorus-based, nitrogen-based, kana inorganic hydroxides) inoshanda kuburikidza ne endothermic reactions kana inodzivirira layer kugadzirwa, ichipa zvirinani kuita kwezvakatipoteredza.
Magadzirirwo Zvikamu:
- Adhesive Base Material: Epoxy resin, polyurethane, kana acrylic.
- Phosphorus-Based Flame Retardant: 10–15% (semuenzaniso,ammonium polyphosphate APPkana tsvuku phosphorus).
- Nitrogen-Based Flame Retardant: 5-10% (semuenzaniso, melamine cyanurate MCA).
- Inorganic Hydroxides: 20-30% (semuenzaniso, aluminium hydroxide kana magnesium hydroxide).
- Plasticizer: 1-3% (inovandudza kushanduka).
- Kurapa Agent: Yakasarudzwa zvichienderana nemhando yekunamatira.
- Solvent: Sezvinodiwa (inogadzirisa viscosity).
Hunhu:
- Zvakanakira: Hushamwari kwezvakatipoteredza, hapana gasi rine muchetura rinobuda, rinoenderana nemirau.
- Zvakaipa: Kudzika kwemoto kudzoreredza kunyatsoshanda, huwandu hwekuwedzera hwekuwedzera, hunogona kukanganisa michina zvivakwa.
4. Mafungiro Akakosha Mukugadzira Dhizaini
- Flame Retardant Sarudzo:
- Halogenated: Kushanda kwakanyanya asi kunoisa njodzi kwezvakatipoteredza uye hutano.
- Halogen-Yemahara: Eco-inoshamwaridzika asi inoda huwandu hukuru.
- Kugarisana: Ita shuwa kuti murazvo unodzoreredza haukonzeredze delamination kana kuderedza kuita kwekubatana.
- Processability: Dzivisa kuvhiringidzwa nekurapa uye kuyerera.
- Environmental Compliance: Sarudza halogen-yemahara sarudzo kusangana neRoHS, REACH, nezvimwe.
5. Typical Applications
- Kuvaka: Zvisimbiso zvisingadziviriri moto, zvinonamira zvechimiro.
- Electronics: Circuit board encapsulation adhesives, conductive adhesives.
- Automotive: Headlight adhesives, emukati adhesives.
6. Kugadziriswa Kwekugadzirisa Mazano
- Kuvandudza Flame Retardancy:
- Synergistic misanganiswa (semuenzaniso, halogen-antimony, phosphorus-nitrogen).
- Nano flame retardants (semuenzaniso, nano magnesium hydroxide kana nano ivhu) kuvandudza kushanda zvakanaka uye kuderedza huwandu hwekuwedzera.
- Kuvandudza Mechanical Properties:
- Tougheners (semuenzaniso, POE kana EPDM) kuwedzera kuchinjika uye kukanganisa kuramba.
- Kusimbisa mafirita (semuenzaniso, girazi fiber) kuwedzera simba uye kusimba.
- Kuderedza Mutengo:
- Gadzirisa mirazvo yekudzosa moto kuti uderedze kushandiswa uchisangana nezvinodiwa.
- Sarudza zvinhu zvisingadhuri (semumba kana zvakasanganiswa zvinodzoreredza moto).
7. Zvakatipoteredza uye Regulatory Zvinodiwa
- Halogenated Flame Retardants: Kurambidzwa pasi peRoHS, REACH, nezvimwewo; shandisa nekuchenjerera.
- Halogen-Yemahara Flame Retardants: Inopindirana nemirairo; ramangwana maitiro.
8. Pfupiso
Adhesive flame retardant formulations inofanirwa kugadzirwa zvichibva pane chaiwo mashandisirwo uye zvinodiwa zvekutonga, kusarudza pakati pehalogenated kana halogen-yemahara sarudzo. Halogenated flame retardants inopa kushanda kwepamusoro asi inoisa njodzi kwezvakatipoteredza, nepo halogen-yemahara dzimwe nzira dziri eco-hushamwari asi dzinoda huwandu hwekuwedzera hwekuwedzera. Nekugadzirisa magadzirirwo nemagadzirirwo, kuita kwepamusoro-soro, kushamwaridzana kwezvakatipoteredza, uye inodhura-inoshanda marimi anodzoreredza anonamatira anogona kugadzirwa ekuvaka, zvemagetsi, zvemotokari, uye mamwe maindasitiri.
