Abstract
The invention relates to a method for producing an acrylate polymer by using a high-activity low-temperature starting type initiating agent. Reaction monomers comprise methyl acrylate and butyl acrylate. The method is characterized in that the acrylate polymer is polymerized by the high-activity low-temperature starting type initiating agent, an emulsifying agent and the reaction monomers through polymerization, the high-activity low-temperature starting type initiator is azodiisobutyronitrile or azodiisopropyl imidazoline hydrochloride, and the use amount of the initiating agent is 0.02-0.5% of the total mass of the reaction monomers and is 0.04% preferably. In the method, the high-activity low-temperature starting type initiating agent is adopted, so that the reaction can be performed at low temperature, and the accidents of high temperature kettle spilling and the like caused by excess high temperature are prevented, therefore environmental pollution, resource wasting, personnel injuries and the like can not be caused, and the safety factor is increased accordingly.
Description
Technical field
The present invention relates to a kind of method of producing acrylic polymer with high reactivity cold-starting type initiator.
Background technology
Polyvinyl chloride (PVC) is a kind of good general-purpose plastics, be widely used, annual volume of production and marketing is very huge, and acrylic polymer is a kind of good polyvinyl chloride processing aid, in the polrvinyl chloride product course of processing, can impel polyvinyl chloride (PVC) RESINS to quicken fusion, reduce the required energy that expends of processing, improve the goods various aspects of performance.What the polyreaction of normal acrylic resin adopted is the Sodium Persulfate initiator, this initiator has low price, be easy to advantages such as buying, but the reaction start-up temperature of Sodium Persulfate is more than 65 degrees centigrade, adopt higher start-up temperature, the not good boiling point that causes temperature in the kettle to reach water of exothermic peak control after the reaction beginning causes the accident of emitting still, cause the bigger waste and the environmental pollution of raw material, emit the still accident may have the possibility of scalding the workman simultaneously.
Summary of the invention
According to the prior art deficiency, technical problem to be solved by this invention is: a kind of method of producing acrylic polymer with high reactivity cold-starting type initiator is provided, this method production process is carried out at low temperatures, high temperature can not occur and emit accidents such as still, can not cause environmental pollution and injury to personnel.
The technical solution adopted for the present invention to solve the technical problems is: a kind of method of producing acrylic polymer with high reactivity cold-starting type initiator is provided, reaction monomers is methyl methacrylate and butyl acrylate, it is characterized in that: use high reactivity cold-starting type initiator, emulsifying agent and reaction monomers to be polymerized, described high reactivity cold-starting type initiator is Diisopropyl azodicarboxylate or azo di-isopropyl imidazoline salt hydrochlorate, consumption is the 0.02%-0.5% of reaction monomers quality, wherein preferred 0.04%.
Described reaction is divided into three sections to be carried out, and three sections reaction monomers consumptions are identical.
Described emulsifying agent is sodium lauryl sulphate or sodium laurylsulfonate.
The consumption of described emulsifying agent is the 0.2%-2% of reaction monomers quality.
The mass ratio of described reaction monomers methyl methacrylate and butyl acrylate is 1.3: 1.
The invention has the beneficial effects as follows: this method adopts high reactivity cold-starting type initiator, can be to react at low temperatures to carry out, prevented that Yin Wendu is too high and high temperature that cause emits accidents such as still, can not cause environmental pollution, the wasting of resources and injury to personnel etc., therefore safety coefficient also increases.
