Abstract
The invention relates to a method for increasing the anti-impact force of PVC (Polyvinyl Chloride) by adopting nano-magnesium hydroxide. The method is characterized by adding a vinyl alcohol monomer, pure water, a dispersing agent, an initialing agent, an anti-impact modifying agent and a conventional amount of fatty acid zinc hot stabilizer and a KZ terminating agent to a reaction kettle, and simultaneously adding the nano-magnesium hydroxide to the reaction kettle, wherein the mass proportion of the monometer to the pure water to the dispersing agent to the initiating agent to the nano-magnesium hydroxide is 95-100: 120-300: 8-10: 1.5-3.0: 4-6, and the temperature of polymerization reaction is 58-65 DEG C. The method has the advantages of convenience in operation, cost saving, improvement of production efficiency, energy conservation and environmental protection. The produced PVC tubular product has the characteristics of high strength and high tenacity, and is strong in anti-impact capacity and great in market competitiveness.
Description
Technical field
The present invention relates to a kind of method of the PVC of raising anti-impact force, relate in particular to a kind of method that adopts nano-sized magnesium hydroxide to improve the PVC anti-impact force.
Background technology
Continuous progress along with scientific and technological level, the PVC material is applied in every field more and more widely, PVC material in the market has rigidity and toughness two specific characters simultaneously, but shock resistance is not very desirable, be difficult to reach people's requirement, do not have the effect of transmitting striking energy, therefore not ageing-resistant, weathering resistance is bad, work-ing life is short, be not suitable with severe environment and use, the shock resistance that how to change plastics has become the current major issue that should solve.
Summary of the invention
The object of the present invention is to provide a kind of method that adopts nano-sized magnesium hydroxide to improve the PVC anti-impact force, it is poor to overcome present PVC shock resistance, not ageing-resistant, the defective that weathering resistance is bad.
The technical solution used in the present invention is as follows:
The fatty acid zinc thermo-stabilizer and the KZ terminator that in reactor, add vinyl chloride monomer, pure water, dispersion agent, initiator, anti-impact modifier and convention amount, wherein in reactor, add simultaneously nano-sized magnesium hydroxide, the mass ratio of monomer, pure water, dispersion agent, initiator and the nano-sized magnesium hydroxide that adds is 95-100: 120-300: 8-10: 1.5-3.0: 4-6, and polymeric reaction temperature is 58-65 ℃.
The present invention by adjusting the composition and engineering control condition of polyreaction, namely by adding the nano-sized magnesium hydroxide of appropriate amount, makes the anti-impact force of PVC improve more than 2.5 times under the condition that does not change existing main production plant.
The present invention has the following advantages: the present invention is under the condition that does not change existing main production plant, improve the anti-impact force of PVC more than 2.5 times, saved power, energy consumption, improved plant capacity, the production system operating safety is stable, has preferably economic benefit.
