Preparation process of antistatic organic glass

Abstract

The invention provides a preparation process of antistatic organic glass. The preparation process sequentially comprises the steps of prepolymerized slurry preparation, antistatic agent addition, moldfilling, low temperature polymerization, high temperature polymerization, cooling and stripping and adsorption separation. An antistatic agent is a surfactant with hydrophilic lipophilic groups. Thestep of antistatic agent addition is added in the preparation process of the organic glass, so that the prepared organic glass contains the surfactant, the surfactant penetrates into the surface of the organic glass to form a smooth surfactant molecular layer, the friction coefficient on the surface of the organic glass is reduced, and the probability of static electricity generated by friction isreduced. At the same time, the hydrophilic groups arranged outwards on a surfactant molecular layer absorb trace water in the environment, and the trace water is adsorbed on the surface of the organic glass to form a conductive layer, the surface resistance of the organic glass is effectively reduced, electric charges are difficult to accumulate on the surface of the organic glass, and the antistatic effect can be achieved accordingly.

Description

technical field [0001] The invention relates to the technical field of production and preparation of plexiglass, in particular to a preparation process of antistatic plexiglass. Background technique [0002] Plexiglass is a polymer compound formed by the polymerization of methyl methacrylate. It is an important thermoplastic that was developed earlier. Plexiglass has good transparency, chemical stability, mechanical properties and weather resistance, and is easy to dye. Easy processing, beautiful appearance and so on. [0003] The surface resistance of the plexiglass produced by the prior art is large, so it is easy to accumulate charges on the surface to generate static electricity in a dry environment, thereby causing unexpected static electricity hazards. Explosions and fires may occur in places where there are flammable and explosive materials or dust and oil mist. [0004] Aiming at the problem that organic glass is prone to generate static electricity in the prior ar...
