Problems solved by technology

[0003] However, the prepared masterbatch does not yet have the function of fire warning. Although general plastic combustion will produce indicator substances such as sulfur dioxide, sulfur dioxide is a common substance in the air and should not be used as an indicator.

preparation example Construction

[0020] A preparation method of a flame retardant antistatic masterbatch with a fire early warning indicator, comprising the following steps:

[0021] Step 1. Put 20%~70% carrier, 4%~20% flame retardant, 15%~50% antistatic agent, and 3%~20% dispersant in a pressurized kneader for 30 minutes~ 50 minutes, the temperature is 170 ° C; obtain the masterbatch blank;

[0022] Step 2: Grinding ferrous ammonium sulfate crystals into powder, putting them into the masterbatch blank and mixing, the mixing temperature is not higher than 100°C;

[0023] Step 3, using twin-screws to granulate the masterbatch blank mixed with ferrous ammonium sulfate crystals to form a flame-retardant and antistatic masterbatch with a fire warning indicator; the temperature of the twin-screws is 75°C to 90°C.

Embodiment 1

[0025] Flame-retardant antistatic masterbatch of the present invention, its weight consists of:

[0026] Linear High Pressure Polyethylene 70%

[0027] Magnesium Hydroxide 4%

[0028] Phosphoric acid 20%

[0029] Polyethylene wax 3%

[0030] Ammonium Ferrous Sulfate 3%

[0031] Plasticize high-pressure polyethylene, antimony trioxide, dithiocarbamate and polyethylene wax in a pressurized kneader for 30 to 50 minutes at a temperature of 170°C, then mix in ferrous ammonium sulfate, and then use a twin-screw to make Granules were granulated at 90°C.

Embodiment 2

[0033] Flame-retardant antistatic masterbatch of the present invention, its weight consists of:

Abstract

The invention relates to a flame retardant and antistatic master batch with a fire prewarning indicator. The flame retardant and antistatic master batch is prepared from the following raw materials inpercentage by weight: 20 to 70 percent of a carrier, 4 to 20 percent of a flame retardant, 15 to 50 percent of an antistatic agent, 3 to 20 percent of a dispersant and 2 to 4 percent of ammonium ferrous sulfate. At high temperature, the ammonium ferrous sulfate can be decomposed to produce ammonia used as the fire prewarning indicator. At the temperature of 110 DEG C, the ammonium ferrous sulfatecan be decomposed to produce the ammonia; the ammonia has pungent smell; generally, air contains a little of alkaline gas and a lot of acidic gas (such as sulfur dioxide), so that the ammonia which is the alkaline gas is more suitable for being used as a detection indicator; a plastic product disclosed by the invention has a chance to prewarn a fire before the fire occurs, and the possibility ofmisreporting is low.

Description

technical field [0001] The invention relates to a functional masterbatch for plastic processing, in particular to a flame-retardant and antistatic masterbatch with a fire warning indicator and a preparation method thereof. Background technique [0002] In the preparation of plastics, synthetic resin is used as a carrier, and a variety of plastic functional additives are added, such as toughening, antistatic, coloring, flame retardant, extinction and other additives, to prepare functional masterbatches. Plastic modification by functional masterbatch method has the advantages of convenient use, clean environment, good fineness dispersion and stable quality. Patent 200810122321.3 discloses a flame retardant and antistatic masterbatch and its preparation method. This patent can prepare a flame retardant and antistatic masterbatch with high conductivity, excellent flame retardancy, less smoke, and low cost. Good quality, low price, convenient production, and high-grade products....
