Embodiment Construction

[0035]In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] Such as Figure 1 to Figure 8 Shown, a kind of chlorinated polyethylene production technique of the present invention, this technique comprises the steps:

[0037] Step 1: adding hydrochloric acid to the polyethylene, and suspending the polyethylene therein after the hydrochloric acid reacts with the polyethylene;

[0038] Step 2: After step 1 is completed, add oxidizing agent and initiator to replace;

[0039] Step 3: after the replacement in step 2 is completed, feed chlorine to carry out chlorination reaction;

[0040] Step 4: after step 3, enter chlorine gas for chlorination for 30 minutes and then filter to obtain a high-concentration chlorinated polyethylene solution;

[0041] Step five: the chlorinated polyethylene solution in step...

Abstract

The invention belongs to the technical field of chlorinated polyethylene preparation, and particularly relates to a production process of chlorinated polyethylene. The process comprises the followingsteps: adding hydrochloric acid into the polyethylene, carrying out a reaction on the hydrochloric acid and the polyethylene, and then dissolving the polyethylene; after the polyethylene is dissolved,adding an oxidizing agent and an initiator for replacement; after the replacement is completed, introducing chlorine to carry out a chlorination reaction; after the chlorination is carried out through the introduction of the chlorine for 30 minutes, carrying out filtration treatment to obtain a high-concentration chlorinated polyethylene solution; feeding the chlorinated polyethylene solution into a filter for deacidification; feeding the chlorinated polyethylene solution subjected to filtration and deacidification into a centrifugal machine for dewatering, and then carrying out drying to obtain a chlorinated polyethylene product; and carrying out washing, drying and sieving on the chlorinated polyethylene product obtained in the step 6 through a chlorinated polyethylene comprehensive treatment device. The process is mainly used for producing chlorinated polyethylene on a large scale, and the three working procedures comprising washing, drying and sieving of chlorinated polyethylene are integrated into one device, so that the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of chlorinated polyethylene, in particular to a production process of chlorinated polyethylene. Background technique [0002] Chlorinated polyethylene, white powder in appearance, non-toxic and tasteless, is a saturated polymer material with excellent weather resistance, ozone resistance, chemical resistance and aging resistance, good oil resistance, flame retardancy and coloring performance. Good toughness, good compatibility with other polymer materials, high decomposition temperature. With the development of the economy, the domestic demand for chlorinated polyethylene is increasing, especially the development of the wire and cable industry and the auto parts manufacturing industry, which has driven the consumer demand for chlorinated polyethylene. In the production process of chlorinated polyethylene, it needs to be dried and then made into powder. [0003] When using the aqueous phase s...
