Embodiment 1

[0007] Adjust the temperature of the reaction vessel to 60°C, take 30kg of polyhexamethylene adipamide, put it into the reaction kettle, stir, and at the same time add 30kg of propylene carbonate, then add 30kg of diethyl phthalate, add 10kg of silicon dioxide, and then Add 10kg of graphite, then add 10kg of diboron trioxide and 20kg of polyurethane in turn. After stirring thoroughly, heat to 200°C and keep for 10h. After cooling, a flame-retardant, acid- and alkali-resistant plastic containing polyhexamethylene adipamide is obtained. Determination of acid-base time is 20 days.

Embodiment 2

[0009] Open the reaction container, adjust the temperature to 60°C, take 40kg of polyhexamethylene adipamide, put it into the reaction kettle, stir, and add 40kg of propylene carbonate, 40kg of diethyl phthalate, and 20kg of silicon dioxide , then add 20kg of graphite, then sequentially add 20kg of diboron trioxide and 30kg of polyurethane, after stirring thoroughly, heat to 200°C and keep for 10h, and after cooling, a flame-retardant, acid- and alkali-resistant plastic containing polyhexamethylene adipamide is obtained. The acid-base time is 25 days.

Embodiment 3

[0011] Adjust the temperature of the reaction vessel to 60°C, take 35 kg of polyhexamethylene adipamide, put it into the reaction kettle, stir, add 35 kg of propylene carbonate, then add 35 kg of diethyl phthalate, add 15 kg of silicon dioxide, and then Add 15kg of graphite, then add 15kg of diboron trioxide and 25kg of polyurethane in turn. After stirring thoroughly, heat to 200°C and keep for 10h. After cooling, a flame-retardant, acid- and alkali-resistant plastic containing polyhexamethylene adipamide is obtained. Determination of acid-base time is 23 days.

Abstract

The invention relates to flame-retarding acid-alkali-resistant plastic comprising polyhexamethylene adipamide. The plastic is composed of the following components, by weight, 30-40 parts of polyhexamethylene adipamide, 30-40 parts of propylene carbonate, 30-40 parts of diethyl phthalate, 10-20 parts of silicon dioxide, 10-20 parts of graphite, 10-20 parts of boron trioxide, and 20-30 parts of polyurethane. The prepared plastic comprising polyhexamethylene adipamide has good flame retarding performance and acid-alkali resistance.

Description

technical field [0001] The invention relates to a flame retardant acid and alkali resistant plastic, in particular to a flame retardant acid and alkali resistant plastic containing polyhexamethylene adipamide. Background technique [0002] At present, in-depth research on plastics is currently being carried out at home and abroad, and some of the research has achieved some remarkable scientific research results. In terms of the specific properties of plastics, such as the flame retardant effect and acid and alkali resistance effect of plastics, there are few studies on the combination of the two at the same time, and there are few reports. Plastics with good flame retardancy and acid and alkali resistance are widely used, but there are few types of plastics with both flame retardancy and acid and alkali resistance on the market. Alkaline plastics are necessary. Contents of the invention [0003] The technical problem to be solved: the problem of poor flame retardancy and...
