Halogen-free inflaming retarding permanent antistatic polypropylene composite material and preparation method

Abstract

The invention relates to a halogen-free inflaming retarding permanent antistatic polypropylene composite material and a preparation method. The halogen-free inflaming retarding permanent antistatic polypropylene composite material is manufactured by the composite materials with the following weight preparation ratio: 40%-70% of polypropylene,5%-15% antistatic agents,1%-8% compatilizer, 5%-30% fire retardant, 0.1%-0.5% antioxygen, and 0.1%-0.5% lubricant. The preparation method comprises the following steps: weighing materials based on the weight preparation ratio; putting all the materials into a high-effective mixing machine to mix for 2-5 minutes and discharging the materials; and putting the uniformly blended materials in a double screw extruder and squeezing out prilling. Compared with the prior art, the halogen-free inflaming retarding permanent antistatic polypropylene composite material has an excellent inflaming retarding feature, 1.6 millimeters inflaming retarding V0 level, and permanent anti-static electricity. The surface resistance is 1010 omega. The halogen-free inflaming retarding permanent antistatic polypropylene composite material has the advantages of being good in mechanics performance, capable of satisfying product requirements and inflaming retarding performance, greatly improving the surface resistance of the composite material, and achieving a good antistatic level.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant permanent antistatic polypropylene composite material and a preparation method thereof. The material can be used to produce environmentally friendly products with high flame retardancy and good antistatic properties, and has great potential in the fields of electronics, home appliances, and packaging. Very broad application prospects. Background technique [0002] Polypropylene material is widely used in many fields because of its excellent mechanical properties and cost performance. The development of flame-retardant PP has expanded the new field of PP product application. The addition of antistatic agent will further add a new direction in the field of PP materials within a certain filling range, so that the composite material has good mechanical properties and excellent flame retardancy. , It also prevents accidents caused by static electricity, and has extremely broad application prospects in...

Problems solved by technology

[0003] At present, a variety of flame-retardant and antistatic polypropylene composite materials have appeared at home and abroad, and the scope of application is gradually expanding, but the halogen-free flame-retardant permanent antistatic polypropylene composite with high-efficiency permanent antistatic and excellent environmental protection and halogen-free flame retardancy Fewer materials and relatively expensive

At present, the addition of halogenated flame retardants is often used to meet the flame retardancy of composite materials, but the price is relatively high and does not meet environmental protection requirements. Highly filled flame retardants also lead to a decrease in the impact of composite materials

However, general halogen-free flame retardants are easy to absorb water and precipitate out of flame retardants, which affect the processing of composite materials and the appearance of products.

Now the general antistatic agent is ionic antistatic agent, although the effect is good, but the short-term effect is not permanent; conductive carbon black can be used as a permanent antistatic agent, but because of the large amount of use, the production operability is difficult, and the development prospect is not good.
