Thermal decomposition temperature of the MAH-g-CPVC/PVC composite material is more than 15-20 DEG C higher than that of normal CPVC resin. Vicat softening temperature of the MAH-g-CPVC/PVC modified plastic profile can reach 90-125 DEG C, and 110 DEG C to the greatest extent, and long-time use temperature is 95 DEG C.

Description

MAH-g-CPVC/ PVC composite modification technology and manufacture method
Technical field
The present invention relates to the modification technology of polyvinyl chloride (PVC) material and the manufacture method of plastic material.
Background technology
Pvc material, particularly rigid polyvinyl chloride material can as structured material, be widely used in the building materials fields such as door-window section bar, tubing, sheet material owing to have preferably tension, bending resistance, resistance to compression and impact resistance.Fast development along with China's economy, the construction market that comprises civilian residential architecture constantly enlarges, improving constantly of living standards of the people, people have higher requirement to the thermotolerance of building materials, weathering resistance, safe handling temperature etc., original plastic material with pvc material production shows as poor heat resistance in severe cold area uses, weathering resistance is poor, can not be satisfactory in the application process.The present invention proposes a kind of new plasticity section bar prescription, improved the function that the thermotolerance, shock resistance, weathering resistance aspect of igelite section bar are used, satisfied the function that material of construction is used at severe cold area, performance and the use value of plastic material have been improved, having enlarged range of application, is a kind of high functional plastics section bar of excellent property.
Summary of the invention
The present invention relates to the modification technology of polyvinyl chloride (PVC) material and the manufacture method of plastic material, the manufacture method of a kind of maleic anhydride (MAH) grafting chlorinated polyvinyl chloride (CPVC) and polyvinyl chloride (PVC) blending and modifying plastic material, the i.e. manufacture method of maleic anhydride graft chlorinated polyvinyl chloride/polyvinyl chloride (MAH-g-CPVC/PVC) modified plastics section bar.
Chlorinated polyvinyl chloride (CPVC) is heat-resisting than the high 30-40 of PVC ℃ than polyvinyl chloride (PVC).Although by introducing chlorinated polyvinyl chloride resin (CPVC), mate various auxiliary agents, carrying out blending and modifying with polyvinyl chloride (PVC) RESINS can improve in function aspects such as the Physical Mechanical of material, thermostability, weathering resistancies, but the melt temperature of CPVC resin is near its heat decomposition temperature, easily caused thermolysis in the machine-shaping goods process, cause the goods shock resistance not improve, processing characteristics descends on the contrary, the CPVC material is used be restricted.
Given this, with maleic anhydride graft chlorinated polyvinyl chloride (MAH-g-CPVC) matrix material as material modified, with polyvinyl chloride resin as resin-based materials, add according to a certain percentage various auxiliary agents, under specific temperature, use the mixer unit to carry out blend and make MAH-g-CPVC/ PVC matrix material, produce MAH-g-CPVC/ PVC modified plastics section bar by double-screw plastic extrusion machine extrude, finalize the design cooling, fixed length cutting.
Because MAH-g-CPVC matrix material heat decomposition temperature is than common CP VC resin more than high 15-20 ℃, not only satisfied the melt processing temperature of section bar, and the vicat softening temperature of the MAH-g-CPVC/ PVC modified plastics section bar of producing can reach 90-125 ℃, maximum operation (service) temperature can reach 110 ℃, the life-time service temperature is 95 ℃, improved the thermotolerance of igelite section bar, shock resistance, the function that the weathering resistance aspect is used, satisfied the function that material of construction is used at severe cold area, performance and the use value of plastic material have been improved, having enlarged range of application, is a kind of high functional plastics section bar of excellent property.
MAH-g-CPVC/ PVC modified plastics section bar basic recipe: polyvinyl chloride resin 80-90 part, MAH-g-CPVC matrix material 10-20 part; Chlorinatedpolyethylene (CPE) 6-9 part; Lead salt one package stabilizer 3-5 part; Titanium dioxide 3-6 part; Processing aid 1-3 part; Calcene 15-25 part.
MAH-g-CPVC/ PVC modified plastics section bar production technique: specific mixing temperature is mixed temperature 115-125 ℃ of heat, and heat was done time 10-15 minute, cold mixed temperature 40-45 ℃.
MAH-g-CPVC/ PVC modified plastics section bar extrusion technique: mold temperature 170-185 ℃, temperature of cooling water 14-18 ℃.
