Abstract
The invention relates to a modification technology of chlorinated polyvinyl chloride (CPVC) composite material. Specifically, a solution method is used to graft the maleic anhydride (MAH) to the chlorinated polyvinyl chloride (CPVC) molecular chain so as to prepare the maleic anhydride grafted chlorinated polyvinyl chloride (MAH-g-CPVC) composite material. The thermal decomposition temperature of the composite material is more than 15-20 DEG C higher than that of the normal chlorinated polyvinyl chloride (CPVC) resin, the temperature condition of melting processing is satisfied, the Vicat softening temperature of the composite material is 125-135 DEG C, the highest usage temperature can be 120 DEG C, and the long-term use temperature is 105 DEG C. Thus, defects of the chlorinated polyvinyl chloride (CPVC) resin, for example, the melting temperature of the chlorinated polyvinyl chloride (CPVC) resin is close to or higher than the thermal decomposition temperature, the chlorinated polyvinyl chloride (CPVC) resin is prone to causing thermal decomposition and is high in processing difficulty, and the product is high in frangibility and poor in impact resistance, are all solved, so that the application foreground of the chlorinated polyvinyl chloride (CPVC) material is wider.
Description
Technical field
The present invention relates to the modification technology of a kind of chlorinated polyvinyl chloride (CPVC) matrix material, relate to specifically high functional polymer composites for a kind of plastics (MAH-g-CPVC) and preparation method thereof.
Background technology
The superior physicochemical properties such as that chlorinated polyvinyl chloride (CPVC) plastics have is heat-resisting, weather-proof, colourless, tasteless, the odorless and fire-retardant self-extinguishing energy of resistant to chemical media burn into, be Application Areas tempo novel plastic material faster in recent years, there is very large market potential.Chlorinated polyvinyl chloride (CPVC) material, by forming process, can be made into the various products such as tubing, section bar, sheet material, bar, is mainly used in the fields such as chemical industry, electric utility, interior decoration industry, petroleum industry industry, building trade.But the melt temperature of CPVC resin approaches or exceedes its heat decomposition temperature, in machine-shaping goods process, easily caused thermolysis, difficulty of processing is large, and goods fragility is large, shock resistance is poor, makes the application of chlorinated polyvinyl chloride (CPVC) material be subject to restriction very large.
Summary of the invention
Given this, patent of the present invention adopts solution method that maleic anhydride (MAH) is grafted on chlorinated polyvinyl chloride (CPVC) molecular chain, complete the preparation of maleic anhydride graft chlorinated polyvinyl chloride (MAH-g-CPVC) matrix material, overcome the defect of prior art.
The step of maleic anhydride graft chlorinated polyvinyl chloride (MAH-g-CPVC) matrix material:
1, selecting of chlorinated polyvinyl chloride (CPVC) resin:
Adopt suspension method to produce chlorinated polyvinyl chloride (CPVC) resin.Requirement selects the thin and surface-area of epithelium to want large, the loose PVC resin of compound with regular structure carries out chlorination, its principal feature is segmentation chlorination, utilize controllable segmentation temperature of reaction and pressure, control chlorine rate of diffusion in polyvinyl chloride resin, cl content is controlled at 63-72%, to obtain the uniform chlorinated polyvinyl chloride of chlorination (CPVC) resin.
2, concrete preparation method:
(1) basic recipe of maleic anhydride graft chlorinated polyvinyl chloride (MAH-g-CPVC) matrix material: be 100 parts of chlorinated polyvinyl chloride (CPVC) resins by weight, maleic anhydride (MAH) 5-15 part, benzoyl peroxide (initiator) 1-5 part, 1000 parts of cyclopentanone solution;
(2) first 20% sodium hydroxide (NaoH) aqueous solution is heated to 80-100 DEG C, then adds the uniform chlorinated polyvinyl chloride of chlorination (CPVC) resin reaction 3-5 hours, make the de-appropriate hydrogenchloride (HCL) of chlorinated polyvinyl chloride (CPVC) resin stand-by;
(3) by the chlorinated polyvinyl chloride after dechlorination (CPVC) resin dissolves in cyclopentanone solution, under the condition of 60-100 DEG C of heating, add benzoyl peroxide (initiator) and maleic anhydride (MAH) to stir, stirring velocity 50-80 cycle per minute clock, after the 2-8 hour stirring reaction time (percentage of grafting is controlled at 2-4%), at room temperature wash again 2-6 hour, dehydration 5-20 minute, at 105-110 DEG C, dry 4-8 hour, complete the preparation of maleic anhydride graft chlorinated polyvinyl chloride (MAH-g-CPVC) matrix material.
The beneficial effect of patent of the present invention: the heat decomposition temperature of maleic anhydride graft chlorinated polyvinyl chloride (MAH-g-CPVC) matrix material is than common chlorinated polyvinyl chloride (CPVC) resin more than high 15-20 DEG C, meet melt processing temperature condition, the vicat softening temperature of material reaches 135 DEG C of 125-, maximum operation (service) temperature can reach 120 DEG C, and life-time service temperature is 105 DEG C.Thereby the melt temperature that has overcome chlorinated polyvinyl chloride (CPVC) resin approaches or exceedes its heat decomposition temperature, in machine-shaping goods process, easily caused thermolysis, difficulty of processing is large, goods fragility is large, the defects such as shock resistance is poor, make the application prospect of chlorinated polyvinyl chloride (CPVC) material more extensive.
