Abstract

The invention discloses a preparation method of a flame retardant composition comprising the components in parts by weight: 1-5 parts of borax, 1-2 parts of ammonium sulfate, 2-3 parts of waterborne polyurethane resin, 1-3 parts of monoammonium phosphate, 4-6 parts of an inorganic filler, and 5-10 parts of water. The raw materials are taken according to the proportion, and the waterborne polyurethane resin is added into the water to form a mixed aqueous solution; then the borax and the inorganic filler are ground until the particle size is less than or equal to 0.55 mm; next ammonium sulfate and monoammonium phosphate are together poured into the mixed aqueous solution and are evenly stirred; and finally, the mixture is loaded into a container.

Description

A kind of preparation method of fire-retardant combination

Technical field

The present invention relates to a kind of auxiliary chemicals, particularly relate to a kind of fire-retardant combination.

Background technology

Electronic devices and components play the important and pivotal role in the modern life, it may be said that modern society is just operate on various electronic devices and components. And electronic devices and components are producing, processing or even all suffer from inflammable risk in transportation, especially in use, because of uncontrollable interference of various extraneous factors, the components and parts catching fire event caused emerges in an endless stream. So, the important topic in modern science and technology field it is always up for the flame-retarded technology of electronic devices and components. Instantly the flame-retarded technology adopted has halogen flame retardant mostly, utilizes the strong heat-insulating flame-retardant characteristic that halogen is natural, really can well play flame retardant effect. But, electronic devices and components are due to its particularity, and conventional flame-retarded technology is often while fire-retardant, and the circuit of chaff element device is stable, serious more can open circuit potential etc., cause components and parts to paralyse. So, for this phenomenon, it is desirable to have a kind of safety, anti-flammability still efficiently, can be put the product of use for a long time on market, and cost is cheap simultaneously, because the market of electronic devices and components is huge, if the high cost of flame-retarded technology, then lose the possibility of marketing.

Summary of the invention

For the defect existed in above technology, the preparation method that the present invention provides a kind of fire-retardant combination.

For solving above-mentioned technical problem, the preparation method of fire-retardant combination of the present invention, it is characterised in that comprise the following steps:

The first step, Borax 1��5 part, amine sulfate 1��2 part, waterborne polyurethane resin 2��3 parts, MAP 1��3 part, inorganic filler 4��6 parts, 5��10 parts of water.

Second step, is added to the water formation mixed aqueous solution by waterborne polyurethane resin.

3rd step, is ground Borax and inorganic filler, until granularity is��0.55mm.

4th step, in the mixed aqueous solution before pouring in the lump together with amine sulfate, MAP, uniform stirring.

5th step, contains in container.

Detailed description of the invention

Embodiment 1

A kind of fire-retardant combination, it is characterised in that include consisting of, by weight meter: Borax 2 parts, amine sulfate 1 part, waterborne polyurethane resin 2 parts, MAP 3 parts, inorganic filler 5 parts, 7 parts of water.

The preparation method of fire-retardant combination of the present invention is as follows:

First waterborne polyurethane resin is added to the water formation mixed aqueous solution. Then Borax and inorganic filler are ground, until granularity is��0.55mm. Then in the mixed aqueous solution before pouring in the lump together with amine sulfate, MAP, uniform stirring. Finally contain in container.

Embodiment 2

Make fire-retardant combination according to the method dispensing of embodiment 1, take Borax 2 parts, p-phenylenediamine 1 part, waterborne polyurethane resin 2 parts, MAP 3 parts, inorganic filler 5 parts, 7 parts of water.

The present embodiment is except with except p-phenylenediamine replacement sulfur acid amide, all the other steps are identical with embodiment 1.
