Problems solved by technology

However, the temperature in the process of synthesizing the prepolymer by this method is high (95-105°C), and the energy loss is large, which greatly increases the cost.
Moreover, the solid content of the polymer synthesized by this method has not been significantly improved.

Abstract

The invention relates to solvent-free quick-drying ultra-high-solid-content methyl methacrylate coating resin and a synthetic method thereof. The solvent-free quick-drying ultra-high-solid-content methyl methacrylate coating resin is prepared from the following components in a mixing manner: methyl methacrylate, iso-octyl methacrylate, dodecyl methacrylate, N,N-diethyl-p-tlouidine, benzoperoxide,p-dihydroxybenzene and azodiisobutyronitrile. The solvent-free quick-drying ultra-high-solid-content methyl methacrylate coating resin meets requirements of environmental protection in the world, is added with an accelerant to shorten solidifying time of the coating resin, and can be applied in a wide temperature zone; the solid content of the methyl methacrylate coating resin synthesized by the intermittent bulk polymerization can reach 90% or above, the coating resin film is high in appearance flatness, the properties of the product domestic advanced, and thus, the solvent-free quick-dryingultra-high-solid-content methyl methacrylate coating resin has an important role in pushing development and technical progress of domestic floor coating resin.

Description

technical field [0001] The invention relates to the field of floor paints, in particular to a solvent-free, fast-drying ultra-high solid content methyl methacrylate coating resin and a synthesis method thereof. Background technique [0002] In the context of rapid social and economic development, the market has higher and higher requirements for product performance. However, the traditional resin used in my country's coating industry has a slow curing time, which greatly increases the construction time and slows down the economic growth rate. At present, most of the quick-drying coating resins used in the coatings used in the field of floor construction in my country are imported from Germany, which greatly increases the economic cost. Therefore it is imminent to invent a kind of quick-drying type coating resin. [0003] The Chinese patent with authorized publication number CN 102702438 B discloses a fast-drying and weather-resistant high-solid acrylic resin and a preparat...
