Abstract
The present invention relates to a kind of frp industry additive flame retardant, its component comprises aluminium hydroxide, magnesium hydroxide, antimonous oxide, aluminate coupling agent, ammonia chloride condensed polymer.When the present invention 1: 1 adds, can guarantee oxygen index more than 40, the viscosity centipoise is below 1500, and product brightness is good, deliquescence not, and physicochemical property obviously improves.
Description
The present invention relates to a kind of frp industry additive flame retardant.
In the existing glass reinforced plastic low-smoke and flame retardant technology, use inorganic combustion inhibitor aluminium hydroxide, magnesium hydroxide (United States Patent (USP)) always, reach synergist antimonous oxide (Japanese Patent), its shortcoming is (1) poor fire, when adding at 1: 1, oxygen index is generally about 28, and (2) viscosity is big, and 1: 1 when adding, the viscosity centipoise influences technological forming up to 4500.If add solvent, treat the small molecules solvent evaporates after, stay a large amount of pin holes, the goods physicochemical property is sharply reduced.
The present invention aims to provide a kind of flame retardant resistance height, and viscosity is low, the glass reinforced plastic additive flame retardant of good stability.
Efficient additive flame retardant for composite GRP of the present invention, its component comprises (weight %):
(1) aluminium hydroxide 50-75
(2) magnesium hydroxide 3-10
(3) antimonous oxide 3-10
(4) aluminate coupling agent 3-5
(5) ammonia chloride condensed polymer 15-35
The aluminate coupling agent that the present invention adopts is through the tetraethoxy esterification, and the inorganic fire-retarded thing of activation treatment at high temperature solidifies, and strengthens binding ability, improves the dispersiveness of inorganics in synthetic resins, improves intermiscibility.
It is to coat ammonium chloride through fluorine silicon telomer that the present invention adopts ammonia chloride condensed polymer, and lipophilic group is with on condensation reaction post chlorization ammonium surface, has hydrophobicity, and oxygen index is increased substantially.
Fluorine silicon telomer of the present invention comprises components such as fluorine, silicone oil, white carbon black, atlapulgite.
The present invention compared with prior art has following advantage: when adding at 1: 1 with the unsaturated polyester resin, oxygen index can be brought up to more than 40 by 28, the viscosity centipoise can be reduced to below 1500 by 4500, product brightness is good, and deliquescence, physicochemical property obviously do not improve.
Component comprises (weight %) in the preferred embodiment of the invention:
(1) aluminium hydroxide 64.5
(2) magnesium hydroxide 5
(3) antimonous oxide 7.5
(4) DL-411-A type aluminate coupling agent 5
(5) ammonia chloride condensed polymer 18
The reinforced plastic plate that vibrin is made in 1: 0.8 ratio is closed in this composite flame-retardant agent and 191# insatiable hunger, and detect through " national glass fiber reinforced plastics product quality supervision and test test center " in June, 1991:
Oxygen index 40(HC-02 type oxygen index instrument, 25 ℃ of temperature are according to GB2406-80)
21 ℃ of relative humidity 64% of viscosity centipoise 1.4 * 10(temperature are according to GB7193.1-87)
Crust formula hardness of X=49.4 S=2.6 Cv=5.3%(HBa-1 type hardness tester machines, 21 ℃ of temperature, relative humidity 64% is according to GB3854-83)
Flexural strength X=2.25 * 10MPa S=19 Cv=8.6%(test type LJ-500, span 30mm, 21.5 ℃ of temperature, relative humidity 60% is according to GB1449-83)
