Description

Preparation method of halogen-free flame-retardant POE material
The invention is a divisional application of an invention patent application with the application number of 201410391702.7 and the application date of 2014, 8 and 11, and the invention is named as a halogen-free flame-retardant POE material and a preparation method thereof.
Technical Field
The invention relates to a high polymer material and a preparation method thereof, and particularly relates to a halogen-free flame-retardant POE material and a preparation method thereof.
Background
The POE resin is a novel polyolefin elastomer polymerized by the Dow chemical company in America by taking metallocene as a catalyst, has the advantages of low price, easy molding and processing and the like compared with other polyolefin elastomers, and is widely applied to the fields of automobiles, electronic appliances, building sealing, sports equipment, toughening and modification of polymers and the like.
POE belongs to flammable materials, and with the increasing application of POE, flame retardant modification of POE is imperative.
Chinese patent document CN102585346A discloses a halogen-free flame-retardant POE composite material, which is prepared from POE resin, a halogen-free composite flame retardant, a modifier, a lubricating dispersant and an antioxidant, wherein the halogen-free composite flame retardant is composed of active magnesium hydroxide/active aluminum hydroxide, zinc borate and microcapsule red phosphorus, and the antioxidant is single antioxidant 1010. The halogen-free flame-retardant POE composite material has the following defects: (1) the flame retardant with the dosage higher than that of POE (polyolefin elastomer) is used for obtaining a better flame retardant effect, so that the mechanical property of the POE composite material is reduced, a modifier is needed for improving the mechanical property of the material, and meanwhile, the proportion of the POE composite material is increased, so that the production cost is further increased. (2) With the addition of modifiers, the elongation at break is still low (less than 650%), so that the use is somewhat limited. (3) The heat aging resistance is poor, the tensile strength change rate is more than 10 percent and the elongation at break change rate is more than 15 percent after aging for 168 hours at 80 ℃.
Disclosure of Invention
One of the purposes of the present invention is to solve the above problems and provide a halogen-free flame retardant POE material which has a good flame retardant effect, a low production cost, a good mechanical property, and no need of any modifier.
The invention also aims to provide a preparation method of the halogen-free flame-retardant POE material.
The technical scheme for realizing one purpose of the invention is as follows: a halogen-free flame-retardant POE material is prepared from the following components in parts by weight: 100 parts of POE resin, 25-60 parts of halogen-free composite flame retardant and 0.1-1.0 part of antioxidant; preferably 100 parts of POE resin, 35-40 parts of halogen-free composite flame retardant and 0.2-0.5 part of antioxidant.
The halogen-free composite flame retardant consists of active ammonium polyphosphate (APP), Melamine Cyanuric Acid (MCA) and tris (2-hydroxyethyl) isocyanurate in a weight ratio of 100: 8-20.
The active ammonium polyphosphate is obtained by modifying ammonium polyphosphate by using a silane coupling agent, wherein the weight ratio of the ammonium polyphosphate to the silane coupling agent is 100: 2-100: 4.
In order to improve the heat aging resistance of the halogen-free flame-retardant POE material, the antioxidant is preferably a composite antioxidant consisting of an antioxidant 1010 and an antioxidant 168 according to the weight ratio of 1: 1-1: 3.
the preparation method of the halogen-free flame-retardant POE material comprises the following steps of pouring POE resin, active ammonium polyphosphate, melamine cyanuric acid, tris (2-hydroxyethyl) isocyanurate and an antioxidant which are weighed according to a formula into a high-speed mixer to be mixed until the temperature of the material rises to 65-75 ℃ due to friction heat generated by mixing, discharging and cooling, ② feeding the cooled mixed material into a double-screw extruder to be melted and extruded, and cooling and drawing the extruded strips into a granulator to be granulated to obtain the halogen-free flame-retardant POE material.
the antioxidant in the step ① is a composite antioxidant which is composed of an antioxidant 1010 and an antioxidant 168 according to the weight ratio of 1: 1-1: 3.
the active ammonium polyphosphate is obtained by modifying ammonium polyphosphate by using a silane coupling agent, wherein the weight ratio of the ammonium polyphosphate to the silane coupling agent is 100: 2-100: 4.
in step ②, the temperature of each zone of the double-screw extruder is T1=80℃～85℃，T2=85℃～90℃，T3=90℃～100℃，T4=100～110℃，T5=110～120℃，T6=120～130℃，T7=130～140℃，T8=140～145℃，T9=130～140℃，TDie=135～140℃。
The invention has the following positive effects: (1) the halogen-free flame-retardant POE material disclosed by the invention adopts a halogen-free composite flame-retardant system consisting of active ammonium polyphosphate, melamine cyanuric acid and tris (2-hydroxyethyl) isocyanurate, and the halogen-free composite flame-retardant system can obtain a better flame-retardant effect (the oxygen index is greater than 30 and the vertical combustion V-0 level) only by using a small amount, so that the production cost is reduced, and in addition, the material still has higher mechanical properties without a modifier, especially the elongation at break can reach more than 850%, so that the halogen-free composite flame-retardant POE material has wider application. (2) The halogen-free flame-retardant POE material adopts the hindered phenol antioxidant 1010 and the phosphite antioxidant 168 to form the composite antioxidant, so that the heat aging resistance of the material can be greatly improved, the material is aged for 168 hours at the temperature of 80 ℃, and the change rate of the tensile strength and the elongation at break is less than 5 percent.
