Abstract
The invention relates to a halogen-free flame-retardant polyethylene plastic. The polyethylene plastic is characterized by comprising the following components: 100 parts of high-density polyethylene (HDPE), 20 to 50 parts of ethylene-vinyl acetate copolymer (EVA), 5 to 15 parts of sodium lauryl sulfate, 20 to 50 parts of flame retardant, 2.5 to 8.5 parts of organic tin stabilizer, 1 to 5 parts of amino silicon oil, 1.5 to 5 parts of antioxidant, 1 to 5 parts of paraffin, 1 to 5 parts of zinc stearate, and 1 to 3 parts of stearic acid. The obtained polyethylene plastic has good flame-retardant property and low smoke formation quantity.
Description
Technical field
The present invention relates to a kind of Zero halogen flame resistance polyethylene plastics, belong to the plastics field.
Background technology
Vilaterm has meets the inflammable shortcoming of fire, as finishing material, for the sake of security, needs to improve its flame retardant type, and the fire retardant of halogen has shortcomings such as the amount of being fuming is big.
Summary of the invention
Technical problem to be solved by this invention provides the good halogen-free polyvinyl plastics of a kind of flame retardant effect.
For solving the problems of the technologies described above, the present invention realizes like this
The Zero halogen flame resistance polyethylene plastics is characterized in that comprising following component:
100 parts of HDPE, EVA 20-50 part, sodium lauryl sulphate 5-15 part, fire retardant 20-50 part,, organotin stabilizer 2.5-8.5 part, amido silicon oil 1-5 part, inhibitor 1.5-5 part, paraffin 1-5 part, Zinic stearas 1-5 part, Triple Pressed Stearic Acid 1-3 part.
Preferably: 100 parts of fire-retardant LDPE, EVA 25-45 part, sodium lauryl sulphate 8-12 part, fire retardant 35-45 part,, organotin stabilizer 3-5 part, amido silicon oil 1-5 part, inhibitor 2-5 part, paraffin 1-5 part, Zinic stearas 1-5 part, Triple Pressed Stearic Acid 1-3 part.
Fire retardant be white lake, tetramethylolmethane etc. the weight mixture; Inhibitor is a carbon black.
Vinyon of the present invention adopts the twin screw extrinsion pressing to obtain.
The environmental stress cracking resistance of PE is relatively poor; EVA is the random copolymers of ethene and vinyl acetate between to for plastic; Has good flexibility; Toughness and stress cracking resistance, VA (vinyl acetate between to for plastic) content of the EVA that the present invention adopts is that 10-15%, MFR (melt flow rate(MFR)) are 1.5-2.5g/10min, can improve the environmental stress cracking resistance of PE.
Under hot environment, Vilaterm is oxidized easily, even at a lower temperature, uses also easy ageing for a long time; After adding oxidation inhibitor, can improve the environmental stress cracking resistance of PE, less than 1.5 parts; DeGrain, in 1.5-5 part scope, performance significantly improves; Surpass 5 parts, continuing increases DeGrain.After adding carbon black in the component, material dispersed relatively poor, needing to add lubricant stearic acid zinc, Triple Pressed Stearic Acid, paraffin, sodium lauryl sulphate increases mixed effect, and after adding sodium lauryl sulphate, the PE material surface roughness reduction of extruding.
In order to improve the flame retardant properties of PE, need to add fire retardant, the fire retardant that the present invention adopts is white lake, EVA, tetramethylolmethane; In order to increase fire retardant and poly interface binding power, need to add an amount of coupling agent, the coupling agent that the present invention adopts is a silane coupling agent; After needing amido silicon oil simultaneously; Can improve the flame retardant properties of fire retardant, improve the processing characteristics of PE simultaneously, also possibly be and sodium lauryl sulphate performance synergy; But when adding fire retardant with coupling agent, poly tensile strength and Young's modulus are increased substantially, but toughness significantly reduces, the therefore an amount of properties-correcting agent of needs interpolation is with the over-all properties of balance material.The adding of stablizer can make the thermal weight loss temperature of fire retardant improve, and makes system have good thermostability.
