example 1

[0025] Take 10g of dimethyl diallyl ammonium chloride and 100mL of absolute ethanol into a three-necked flask equipped with a thermometer and a reflux device, place the three-necked flask in a water bath, control the temperature of the water bath to 85°C, and stir and mix for 3 minutes , add 8g sodium methpropylene sulfonate, 6g ethylene glycol monovinyl ether and 0.3g lauroyl peroxide to the three-necked flask, stir and react for 2h, then add 3g p-tert-butylcatechol to the three-necked flask, continue stirring React for 40 minutes, the reaction is over, and the product is obtained. The product is placed in a rotary evaporator, and concentrated by rotary evaporation for 15 minutes to obtain a concentrated solution. Then take 20g of polystyrene and 200mL of methyl ethyl ketone and add it to a three-port tube with a thermometer and a reflux device. In the flask, place the three-necked flask in an oil bath, control the temperature of the oil bath to 130°C, stir and dissolve for 3 ...

Abstract

The invention belongs to the technical field of flexible packaging material preparation, and particularly relates to an anti-static film and a preparation method thereof. The method comprises the following steps: firstly, heating dimethyl diallyl ammonium chloride and absolute ethyl alcohol and mixing; adding sodium methallyl sulfonate, ethylene glycol monovinyl ether and the like to carry out reaction to obtain a product; carrying out rotary evaporation and concentration on the product to obtain a concentrated solution; heating polystyrene and methyl ethyl ketone and then dissolving to obtain a mixture, and carrying out reaction between the mixture and 2,4-toluene diisocyanate and a catalyst; subsequently, carrying out rotary evaporation and concentration to dryness to obtain modified polystyrene; finally, mixing the modified polystyrene with chlorinated polypropylene, a toughening agent and the concentrated solution to obtain a premix; carrying out plasticization extrusion and inflation traction to obtain the anti-static film. The anti-static film obtained by the method has good mechanical performance and an anti-static effect; meanwhile, compared with a conventional anti-static film, the anti-static film disclosed by the invention has the advantages of better anti-static effect and longer anti-static period; therefore, the anti-static film is a desired flexible packaging material.

Description

technical field [0001] The invention belongs to the technical field of soft packaging material preparation, and in particular relates to an antistatic film and a preparation method thereof. Background technique [0002] With the rapid development of the electronics industry, the integration of electronic circuit boards is getting higher and higher. The high density of electronic components on the motherboard, the compact wiring, and even the widespread use of surface mount components can easily lead to electrostatic damage to circuit boards. . Based on this, antistatic film packaging materials came into being. [0003] Usually we put the volume resistivity at 10 -2 Objects below Ω·cm are called conductors and have a resistivity of 10 10 Anything above Ω·cm is called an insulator, and the resistance is above 10 -2 ~10 10 Between Ω·cm is semiconductor or antistatic material. As a kind of functional film, antistatic film refers to a functional film that adheres to the sur...
