Multifunctional composite natural cellulose brucite powder material and its modified material and composite mother granules manufacturing method

Abstract

A multifunctional composite powder of natural fibres and brucite, its modifier and the process for preparing its composite mother particles are disclosed. Said flame-retarding, antibacterial and reinforcing composite powder is prepared through superfine pulverizing for brucite, suspension atomizing of modifier, and directional loosening. Its modifier is composed of coupling agent and antibacterial trigger. The process for preparing said mother particles includes mixing modifier, antibacterial material, high-molecular organic polymer and viscosity decreaser, plasticizing, extruding out and cutting to become particles.

Description

[0001] (1) Technical field: the present invention relates to a kind of method that takes natural fiber brucite as raw material to prepare multifunctional composite powder material and its modified material and composite masterbatch, which belongs to the technical field of magnesium compounds. (two) background technology: [0002] 1) Flame retardant material Background technology: There are two types of flame retardant materials, one is inorganic flame retardant material, and the other is organic flame retardant material. Inorganic flame retardant materials generally have the disadvantage of decomposing at low temperature, such as aluminum hydroxide and antimony chloride, aluminum hydroxide is easy to decompose at low temperature, and antimony chloride is toxic and expensive. However, organic flame-retardant materials such as groups containing chlorine, phosphorus, and bromine have the disadvantages of being toxic, easy to decompose, easy to age, and high in cost. Therefore, th...

Problems solved by technology

The reinforcing effect of glass fiber is also quite remarkable, the mechanical properties are almost the same as those of aramid fiber, and it has good flame resistance, formability, aging resistance, yellowing, strong adhesion, good tensile strength and friction resistance, but the cost is high. Complex production process, easy to bend, poor mechanical properties

Reinforcing material with mica as raw material, excellent electrical properties (high strength, insulation resistance, low dielectric loss, corona resistance), excellent mechanical properties, and good heat resistance, moisture resistance, chemical stability and high-energy radiation resistance , but the production cost is high, the viscosity and toughness are poor, and it is not wear-resistant

Other mineral reinforcing materials represented by carbon black have the advantages of better reinforcement, wear resistance and anti-aging performance, but high energy consumption and cost, no tensile strength, easy deformation, and unattractive appearance
