Embodiment Construction

[0017] For overcoming above-mentioned technical problem, the technical scheme that the present invention adopts is as follows:

[0018] A molding compound formula, the ratio is as follows: 5% to 59% glass fiber (5 to 59% GF) and polyamide (PA) hereinafter referred to as "PA+GF5 to 59%", maleic anhydride (Maleicanhydride) 35% ~70%, polyethylene (PE) 30~70%.

[0019] The polyamide (PA) includes all thermoplastic polyamides such as PA6, PA66, PA10, PA11, PA12, and PA1212.

[0020] The molecular formula of maleic anhydride is: C4H2O, also known as: maleic anhydride (MAH)+polyethylene (PE).

[0021] A method for preparing a molding compound, the steps are as follows:

[0022] (1): Use thermoplastic injection molding machine (vertical machine or horizontal machine) to make polyethylene (PE) 30-70% and maleic anhydride (Maleicanhydride) 35%-70% into any desired shape by thermoplastic molding Parts, hereinafter referred to as "Ring" process steps: 1) Polyethylene (PE) 30-70% and ma...

Abstract

The invention provides a formula of die plastic.The formula is characterized in that the die plastic is prepared from 5-59% of glass fibers (GF) and polyamide (PA), 35-70% of maleic anhydride and 30-705 of polyethylene (PE).The die plastic has the advantages that PA+GF and PE plastic particles can be effectively and fully combined through the maleic anhydride, it is guaranteed that two types of materials of different ingredients can meet the combination requirement, meanwhile the use environment requirement that a part contains two different types of materials at the same time is met; the process that local of the part can be welded to any polyethylene material is met; combination of two types of materials is achieved; fuel vapor in a container can be effectively prevented from permeating and volatilizing into air among molecular chains, emission of fuel hydrocarbons is lowered, and the making method is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of compounds and preparation methods, in particular to a formulation and preparation method of a molding compound. Background technique [0002] Molding compound is a type of plastic. Compared with common thermoplastics, molding compound has higher geometric and dimensional stability, more resistance to extreme high heat and high humidity complex environments, chemical resistance, and high mechanical strength. Compared with common thermoplastics, molding compounds have higher geometric and dimensional stability, are more resistant to extreme high heat, high humidity and complex environments, chemical corrosion resistance, and high mechanical strength. It is used in industries such as aerospace, naval vessels and civil ships, firearms, electronic and electrical components, and power equipment components. The molding process of molding compound mainly includes compression molding and injection molding, in add...
