Description
Technical field:
The present invention relates to high molecular fire retardant material preparation method field, particularly the preparation of trimeric-cyanamide cyanurate fire-retardant nylon material.
Background technology:
Along with the development of electric industry, the demand of fire-retardant nylon keeps increasing fast.Though the halogen containing flame-retardant good flame retardation effect, when burning the amount of being fuming big, and produce toxic gas and cause secondary pollution.Melamine cyanurate is called for short MCA, is a kind of polymkeric substance that is polymerized by trimeric cyanamide and cyanuric acid, and being considered to be in bromo-antimony minimum on price/performance index is substitute, has caused the interest on international fire-retardant boundary.As a kind of nitrogen flame retardant, to compare with halogenated flame retardant, toxicity is lower, has the excellent fire retardant over-all properties.Nylon 6 is a kind of good toughness, electrical property excellence, oil resistant, attrition resistant important engineering plastics, but as a kind of flammable plastics, it is used for goods electric, the transportation building field and generally also needs to carry out fire-retardant finish.Therefore, Liu Yuan, Wang Qi, Hu Fuyu, the research of modified cyanurotriamide cyanurate flame-proof PA 6, polymer material science and engineering, 2004,20 (3), 220; Chinese invention patent application number 200510022046.4; Chinese invention patent zI03135668.0.But a kind of mode of above research is that melamine cyanurate is carried out molecule is composite modified, prepares fire-retardant nylon then; Another mode is to be raw material with trimeric cyanamide, cyanuric acid, adopts original position compound mode preparation fire retardant earlier.These two kinds of methods are the raw materials cost height not only, and the method complexity.
Summary of the invention:
In order to address the above problem, the object of the present invention is to provide a kind of employing reaction extrusion method to prepare melamine cyanurate/nylon 6 fire retardant materials.Whole synthesis excellent performances such as the fire retardant material shock resistance of the present invention's preparation, color and luster, and raw materials cost is low, method is simple.The technical solution used in the present invention is:
1) with material, nylon 6, poly cyanamid cyanurate, oxidation inhibitor are prepared burden by weight ratio, mix in high-speed mixer, and the weight part proportioning is:
6 100 parts of nylon
6～16 parts of melamine cyanurates
0.3 part in oxidation inhibitor
2) expressing technique: after mixing of materials is even, material is thrown in the twin screw extruder, extrusion temperature is 200-240 ℃, the main frame revolution is 400r/min～580r/min, reacted 1～2 minute, through check rod, cooling, pelletizing, pellet is in 80～120 ℃ of following vacuum-drying 2～6h.
Described oxidation inhibitor is [β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester (being antioxidant 1010).
The preparation of described trimeric-cyanamide cyanurate fire-retardant nylon material is characterized in that material also comprises 1～4 part retardant synergist.
Described retardant synergist is triphenylphosphate (TPP) or zinc borate.
Adopt expressing technique to be by the advance copy invention: extrusion temperature is 200-240 ℃, and the main frame revolution is 400r/min～580r/min, reacts 1～2 minute.
Consumption further experiment to melamine cyanurate and retardant synergist illustrates below:
Test example 1
Get 6,0.3 part of antioxidant 1010 of nylon of 100 parts, get melamine cyanurate by table 1, in high-speed mixer, mix, after mixing of materials is even, material is thrown in the twin screw extruder, and extrusion temperature is 230 ℃, and the main frame revolution is 480r/min, reacted 1～2 minute, through check rod, cooling, pelletizing, pellet the results are shown in Table 1 in 100 ℃ of following vacuum-drying 4h.
