Abstract
The invention belongs to polymeric material fields, disclose a kind of low water absorption flame-proof glass fibre enhancing PA6 composite material and preparation method.According to parts by weight, low water absorption flame-proof glass fibre of the invention enhancing PA6 composite material includes 43.6~99.3 parts of PA6,5.0~15.0 parts of hydrophobing agents, 10.0~30.0 parts of glasses, 5.0~20.0 parts of fire retardants, 0.2~0.4 part of antioxidant, 0.5~1 part of processing aid.Present invention optimizes the moulding process of the fire-retardant toughened PA6 composite material of low water absorption, PA6 matrix hydrophobic performance is promoted using stearic acid and ammonium stearate, material flame retardant property itself is promoted by MPP, and it adds glass and improves PA6 impact strength, tensile strength, the mechanical properties such as elongation at break, wherein, stearic acid, ammonium stearate can increase the compatibility of MPP Yu PA6 matrix, inhibit to be precipitated, in addition hydrophobing agent itself is generated gas by thermal decomposition and is provided simultaneously with gas phase fire retardation, melamine group in MPP structure has certain hydrophobic performance, it is provided simultaneously with cooperative flame retardant between the two and cooperates with hydrophobic effect.
Description
Technical field
The present invention relates to polymeric material fields, are specifically related to a kind of low water absorption flame-proof glass fibre enhancing PA6 composite wood
Material and preparation method thereof.
Background technique
Nylon 6 (PA6 or polyamide 6) is as the widely used important engineering plastics of one of five large-engineering plastics, tool
There are excellent shock resistance, higher tensile strength, good wear-resisting property and outstanding electrical insulation capability and chemically-resistant
Performance.Such material is mainly used in the fields such as hardware machinery, electric, instrument and meter.However, polyamide is due to its structure
In amido bond, easily form intermolecular hydrogen bonding with hydrone, cause material hygroscopic, rigidity is deteriorated, material ruler caused by absorbing water
It is very little to change the Long-Term Properties for leveraging material, and PA6 is limited in the use in delicate elements field.With product
Continuous development and new standard gradually implementation, more stringent requirements are proposed for tensile strength and toughness of the industry to nylon 6.This
Outside, PA6 belongs to combustible material, and molten drop and dense smoke can be generated after burning, can accelerate the diffusion and sprawling of flame, therefore before use
It needs flame-retardant modified.Therefore, low water absorption enhancing PA6 is an emphasis direction in current such investigation of materials.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of above-mentioned background technique, a kind of low water absorption flame-proof glass fibre increasing is provided
Strong PA6 composite material and preparation method.Low water absorption flame-proof glass fibre of the present invention enhancing PA6 composite material is using stearic acid, hard
Resin acid ammonium modified Pa 6 make its hydrophobicity improve, using MPP be used as fire retardant, with stearic acid, ammonium stearate with it is compatible with it is fire-retardant
Synergistic function.Compared to traditional PA6, which has low water absorption and outstanding flame retardant property.Meanwhile glass additive amount compared with
Low, whole auxiliary agent addition accounting is low, reduces costs, cost performance is higher.
To achieve the object of the present invention, according to parts by weight, low water absorption flame-proof glass fibre of the invention enhances PA6 composite wood
Material comprising 43.6~99.3 parts of PA6,5.0~15.0 parts of hydrophobing agents, 10.0~30.0 parts of glasses, 5.0~20.0 parts of fire retardants,
0.2~0.4 part of antioxidant, 0.5~1 part of processing aid.
Further, the hydrophobing agent is one of stearic acid, ammonium stearate or a variety of.
Further, the fire retardant is melamine polyphosphate (MPP), melamine cyanurate (MCA), trimerization
One of cyanamide is a variety of.
Further, the antioxidant is antioxidant 1010, irgasfos 168, antioxidant 1076, antioxidant 264, antioxidant
One of 245 or a variety of.
Further, the processing aid is the mixture of lubricant, dispersing agent and amino silicane coupling agent.
Preferably, the lubricant is one of stearic amide, paraffin, polyethylene wax or polypropylene wax or a variety of；
The dispersing agent is derivative of fatty acid；The amino silicane coupling agent is KH-550.
On the other hand, the present invention provides a kind of preparation sides of aforementioned low water absorption flame-proof glass fibre enhancing PA6 composite material
Method, the preparation method include:
(1) in high-speed mixer by PA6 particle, hydrophobing agent, fire retardant, antioxidant and processing aid stir 15~
30min, mixing speed 2500r/min；
(2) mixture of PA6 particle in step (1), hydrophobing agent, fire retardant, antioxidant and processing aid is placed in vacuum
It is dry in drying box；
(3) hydrophobing agent, fire retardant, antioxidant and processing aid mixture after will be dry in step (2) be from main spout
It is added, glass is added in side spout, squeezes out in double screw extruder, is granulated；
(4) particle for obtaining the granulation in step (3) is through single screw rod injection molding machine injection molding PA6 batten.
Preferably, mixture is placed in the drying 20~28 hours of 85~95 DEG C of vacuum oven in the step (2).
