Abstract
The invention relates to a composite flame retardant for a silicon rubber additive. The composite flame retardant is prepared from the following effective ingredients: triphenyl phosphate, magnesium stearate, bisphenol A, antimony trioxide and calcium carbonate. A preparation method of the composite flame retardant comprises the following steps of: putting triphenyl phosphate, magnesium stearate and calcium carbonate in a reaction kettle, increasing the temperature to 55-65 DEG C, and stirring; adding a catalyst antimony trioxide and bisphenol A; reducing the pressure, evenly increasing the temperature to 165-180 DEG C, preserving the temperature for 1-1.5 hours, continuously increasing the temperature to 220-250 DEG C, preserving the temperature for 1-2 hours and finishing reaction; discharging materials, naturally cooling the materials for solidification, and grinding the solidified materials in a grinder; pouring the ground materials in a washing kettle, adding absolute ethyl alcohol, washing for 0.5-1 hour, and discharging the washed materials; and drying the materials in a dryer. A silicon rubber product prepared from the flame retardant is good in flame retarding effect.
Description
Technical field
The present invention relates to a kind of fire retardant, relate in particular to a kind of silicon rubber additive composite flame-retardant agent.
Background technology
Silicon rubber is widely used in the every field of producing and living, but because the inflammableness of silicon rubber is also the main Root of Clark Clematis of its development of restriction, the flame retardant resistance that how to improve this product is the direction of the sector technician research always, add the flame retardant resistance material to reach the successful experience of fire-retardant purpose in making the additive of this product a lot, but result is not very desirable yet.Along with the application of this product in high-end fields such as electrical equipment, electronics, aerospaces, also more and more high to the fire-retardant requirement of this product material.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, a kind of silicon rubber additive composite flame-retardant agent is provided, the silicone rubber products good flame retardation effect of using this fire retardant to produce.
