Reinforced transparent sound insulation acrylic plate and preparation method thereof

Abstract

The invention relates to a reinforced transparent sound insulation acrylic plate, which comprises a transparent polymethyl methacrylate plate and plastic cellosilk uniformly embedded in the transparent polymethyl methacrylate plate, and a preparation method comprises the following steps: uniformly mixing a proper amount of methyl methacrylate and an initiator, heating until boiling, then stopping heating, keeping the temperature until a feed liquid reaches a certain viscosity, and then cooling to room temperature to form a pre-polymerized material; adding a release agent and an initiator into the pre-polymerized material, uniformly mixing, and carrying out vacuum defoaming for later use; arranging plastic fibers on a special mold with an acrylic plate, and sealing and fixing the two ends of each plastic fiber; performing mold filling on the pre-polymerized material in a special mold for the acrylic plate, wherein the polymerization time is 2-5 hours; after polymerization is completed, demolding, and the obtaining reinforced transparent sound insulation acrylic plate. The performance of the sound insulation acrylic plate is met, the problem that the base material is separated from the plastic fibers is solved on the premise that the plastic fibers do not need to be post-processed, and the preparation method is simple, low in cost and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of acrylic panels, in particular to a reinforced transparent sound-insulating acrylic panel and a preparation method thereof. Background technique [0002] Sound insulation boards are generally made of plastic glass plates, such as polymethylmethacrylate (PMMA for short), or polymethacrylate (PMMA)-based molding compounds, which have better transparency and sound attenuation. . But also there are following two problems in existing sound insulation board in actual application process: the one, once after being bumped by vehicle, sound insulation board can break into fragments and disperse at once, and vehicle easily rushes out of passage edge from the gap that rupture forms, can't Give more cushioning and proper protection after the accident of vehicle; The 2nd, because it is transparent, birds and other birds and animals can bump into the sound insulation board and be injured or die because they can't disti...

Problems solved by technology

But also there are following two problems in existing sound insulation board in actual application process: the one, once after being bumped by vehicle, sound insulation board can break into fragments and disperse at once, and vehicle easily rushes out of passage edge from the gap that rupture forms, can't After the vehicle has an accident, give more cushioning and proper protection; secondly, because it is transparent, birds and other birds will be injured or killed when they cannot tell that there is a sound insulation wall in front of them when they are flying.

However, the heat treatment requirements are strict and the treatment time is long
