Problems solved by technology

However, once the surface of plexiglass is rubbed, it is easy to accumulate charges, which may affect its transparency due to the adsorption of dust, etc., or cause fire or even explosion.
[0003] At present, the commonly used methods to improve the antistatic performance of plexiglass mainly include adding small molecule antistatic agents and conductive fillers; however, due to the obvious disadvantages of easy migration of antistatic agents, short maintenance time of antistatic properties, and poor transparency of conductive fillers, etc. , the above methods are all at the cost of greatly sacrificing the transparency of PMMA; and another method is to form a layer of antistatic hard film on the surface of PMMA board through coating technology, which perfectly retains the inherent physical properties of the substrate. In addition, it has an excellent function of eliminating static electricity at the same time, which can effectively prevent the accumulation of dust and avoid the possible harm caused by static electricity, but the antistatic film is easy to fall off during use, making the PMMA board lose its antistatic ability

Abstract

The invention provides a PMMA monomer copolymerized organic glass production process. The PMMA monomer copolymerized organic glass production process comprises the following steps: 1) preparing raw materials from the following components in percentage by mass: 79-85% of methyl methacrylate, 5-10% of an antistatic agent, 5-10% of an intermediate monomer and 1-3% of an initiator; 2) weighing the rawmaterials in proportion, adding the methyl methacrylate and the initiator in the step 1) into a dissolving device together, and carrying out mutual dissolution reaction for later use; and 3) weighingthe raw materials in proportion, adding the double-bond-containing antistatic agent in the step 1) and an intermediate monomer into a high-temperature dispersion device together, dissolving the double-bond-containing antistatic agent into the intermediate monomer through ultrasonic treatment, and taking out for later use. The transparent anti-static organic glass formed by copolymerization has the characteristics of high light transmittance, excellent anti-static performance, low possibility of migration of the anti-static agent, simple process and low cost, and has a wide application prospect.

technical field [0001] The invention belongs to the organic glass technical field, more specifically, particularly a kind of PMMA monomer copolymerization organic glass production technology. Background technique [0002] Organic glass (PMMA) is widely used in aerospace manufacturing, construction, transportation, information technology, optical manufacturing and other fields because of its advantages such as high light transmittance, low density, easy processing, and good electrical insulation. However, once the surface of the plexiglass is rubbed, it is easy to accumulate charges, which may affect its transparency due to the adsorption of dust, etc., or cause fire or even explosion. [0003] At present, the commonly used methods to improve the antistatic performance of plexiglass mainly include adding small molecule antistatic agents and conductive fillers; however, due to the obvious disadvantages of easy migration of antistatic agents, short maintenance time of antistati...
