Abstract
This invention discloses a sub-nm SiMg whisker halogenless fire retardant composed of 27-50% ammonia, Mg(OH)2, an epoxy curing agent, stearic acid or Zn stearic acid, a coupler and SiN used in epoxy resin, unsaturated resin, electronic plastic enclosing materials, shells of railway locomotives and fire retardant modification of an adhesion agent and UL 94V-0 level can be got in the additive volume less than 15%.
Description
Technical field:
The present invention relates to a kind of fire retardant.
Background technology:
Relevant at present halogen-free flame retardants product is divided into organic products and inorganic product:
A; Inorganic product.As magnesium hydroxide, aluminium hydroxide etc. are to utilize distinctive thermostability of its inorganic materials and smoke suppressing effect to realize fire-retardant purpose.Because of in application addition greater than 50%, so use this series products that the toughness of material and shock-resistance are reduced significantly, and the machining property of material is reduced, the range of application of this series products is confined in the less demanding product of the physicals of material itself.
B; Organic products.Organic Halogen product of nitrogen phosphorus synergistic, its fire-retardant principle are the combination that gas phase and condensed phase are used.At present domestic and international product development to this type of is more, and characteristics are: have and base material intermiscibility preferably, the machining property of material improves.Defective is: addition is bigger, is generally 30%-40%, influences the physicals of material.Poor heat stability, processing temperature are confined in 300 ℃.Dispersiveness is not good, needs the effect of dispersion agent.Frosting phenomenon appears in the top layer of material easily in application process.
Summary of the invention:
The object of the present invention is to provide the good sub-nano silica-magnesia whisker halogen-less flame-retardant agent of a kind of result of use.
Technical solution of the present invention is:
A kind of sub-nano silica-magnesia whisker halogen-less flame-retardant agent is characterized in that: be made up of following weight item:
Concentration is 27～50% ammoniacal liquor 65～90%
Magnesium hydroxide 5～15%
Epoxy hardener 1～2.5%
Stearic acid or Zinic stearas 0.2～2%
Coupling agent 1～3%
Silicon nitride 5～15%.
Epoxy hardener is solidifying agent ANY1001 or solidifying agent SY-H115.Coupling agent is silane coupling agent KH570 or silane coupling agent KH560.
Result of use of the present invention is good, and it is flame-retardant modified to be used for Resins, epoxy, unsaturated polyester, electronics plastic cement, rail locomotive housing, tackiness agent, and addition can reach the UL94V-0 level 15% with interior, and to satisfy with the hydroxyl be the material modification needs of group.Three-waste free discharge, all recyclable cyclic process of all raw materials is used.The present invention also has following advantage:
1, the organic synthesis fire retardant of Halogen, no antimony environment-friendly high-efficiency does not contain harmful gas.
2. specific conductivity is superior, is lower than 60ns/cm.Be suitable for the processing of electronic apparatus plastic cement.
3. be beneficial to environment, formaldehydeless, heavy metal free composition is beneficial to decompose and reclaims, and meets European environmental protection instruction " ROHS " requirement.
4. mechanical property superior (good with the resin intermiscibility), shock strength are good.
5. weather resisteant is good, but widespread use with in the demanding various types of materials of photostabilization.
6. high temperature resistant reaching more than 400 ℃, ageing-resistant performance is strong, can repeatedly repeat processing.
7. tint permanence is good, can be mixed with shades of colour.
8. ratio of performance to price height is effectively controlled product development, production cost.
The invention will be further described below in conjunction with embodiment:
