preparation example Construction

[0019] The application provides a method for preparing a low-VOC flame-retardant composite filler, comprising the following steps:

[0020] (1) Pulverize boehmite in a pulverizer, cross a 500-mesh sieve, then fully mix boehmite, bentonite, and basic calcium phosphate, and stir in a high-speed mixer for 40-60min to obtain mixture A; the temperature of the high-speed mixer is 70-90°C, the speed is 240-320r / min; the mass ratio of boehmite, bentonite and basic calcium phosphate is (60-80):(20-30):(10-16).

[0021] (2) Add octabromobisphenol S ether and nano-calcium silicate to the mixture A of step (1), fully stir and mix for 20-40min, and cool to room temperature to obtain a low-VOC flame-retardant composite filler; octabromobisphenol S ether , Nano calcium silicate, the mass ratio of mixture A is (40-60): (10-16): (60-80).

preparation example 1

[0023] (1) Take by weighing 600g boehmite, 200g bentonite, 100g basic calcium phosphate, pulverize boehmite in a pulverizer, cross a 500 mesh sieve, then fully mix boehmite, bentonite and basic calcium phosphate, Stir with a high-speed mixer for 40 minutes to obtain mixture A;

[0024] (2) Weigh 400g octabromobisphenol S ether, 100g nano-calcium silicate, and 600g mixture A, add octabromobisphenol S ether and nano-calcium silicate to step (1) mixture A, fully stir and mix for 20min, Cool to room temperature to obtain low VOC flame retardant composite filler P1.

[0025] Wherein the temperature of the high-speed mixer in the step (1) is 70° C., and the rotating speed is 240 r / min.

preparation example 2

[0036] (1) Take by weighing 800g boehmite, 300g bentonite, 160g basic calcium phosphate, pulverize boehmite in a pulverizer, cross a 500 mesh sieve, then fully mix boehmite, bentonite, basic calcium phosphate, Stir with a high-speed mixer for 60 minutes to obtain mixture A;

[0037] (2) Weigh 600g octabromobisphenol S ether, 160g nano-calcium silicate, and 800g mixture A, add octabromobisphenol S ether and nano-calcium silicate to step (1) mixture A, fully stir and mix for 40min, Cool to room temperature to obtain low VOC flame retardant composite filler P2.

[0038] Wherein the temperature of the high-speed mixer in the step (1) is 90° C., and the rotating speed is 320 r / min.

Abstract

The invention relates to a preparation method of a low-VOC flame-retardant composite filling material. Boehmite is crushed in a crushing machine and is sieved by a 500-mesh sieve; then, the boehmite,bentonite and hydroxyapatite are sufficiently mixed and are stirred for 40 to 60 min in a high-speed stirring machine to obtain a mixture; next, tetrabromobisphenol S ether and nanometer calcium silicate are added into the mixture, and are subjected to sufficient stirring and mixing for 20 to 40 min; cooling is performed to reach the room temperature; the low-VOC flame-retardant composite fillingmaterial is obtained. By using the technical scheme, the low-VOC flame-retardant composite filling material is synthesized; the functions of improving the polyolefin flame-retardant performance and VOC performance can be improved at the same time; important popularization values are realized.

Description
