Problems solved by technology

However, adding magnesium carbonate to engineering plastics will cause the mechanical properties of the plastic to decrease, and its heat resistance will also decrease. To achieve good mechanical properties and heat resistance, organic flame retardants such as bromine or phosphorus must be used. , so the preparation of fire-resistant engineering plastics with good mechanical properties and heat resistance and the use of inorganic flame retardants has always been a difficult point in the industry

The magnesium carbonate modified fireproof plastic has good mechanical performance and heat resistance and is good in flame retarding effect.

Description

technical field [0001] The invention relates to the technical field of polymer engineering materials, in particular to a magnesium carbonate modified fireproof plastic and a preparation method thereof. Background technique [0002] Polymer materials such as plastics, rubber, adhesives and fibers are widely used in our daily life. The obvious disadvantage of these materials is that they are flammable or combustible, and a large amount of smoke and harmful gases will be produced when they are burned, which has a serious impact on people's daily life, especially when it involves personal safety issues. Therefore, the flame retardancy of polymer materials is extremely important. Commonly used halogenated flame retardants will decompose a large amount of toxic smoke during combustion, which can easily poison and suffocate people present, affect vision and escape, and even pose a cancer-causing threat. Therefore, many developed countries have banned their use. With the promotion...
