Polymethylmethacrylate waterproof paint and preparation method thereof

Abstract

The invention relates to a polymethylmethacrylate waterproof paint and a preparation method thereof. The waterproof paint consists of components A and B, wherein the component A is a methacrylic acid resin liquid generated by reaction based on methyl methacrylate (MMA) utilized as a main composition, and the component B is an initiator. When the component A is prepared, a hard monomer, a soft monomer and a cross-linking monomer are put in a reaction kettle and evenly stirred, and then heating is carried out; polymethylmethacrylate moulding plastic is put, and then reaction is carried out for 1-6 hours at the temperature of 70-90 DEG C; cooling is carried out until the temperature is 50-65 DEG C, a polymerization inhibitor, an accelerator, sealing wax and a thixotropic agent are added and evenly stirred; and cooling is carried out until the temperature is 30-45 DEG C, and filtration and packaging are carried out so as to prepare the component A resin liquid. The components A and B are evenly stirred and mixed in a proper proportion, then coated, and finally solidified into a film. The waterproof paint has the characteristics of good strength, good elasticity, low temperature hardness, excellent weather resistance and the like, is simple and convenient for construction, can be solidified rapidly, and can be used for waterproof work of rapid transit railway bridge surfaces and super highway subgrades.

Description

technical field

[0001] The invention relates to a waterproof coating, in particular to a polymethyl methacrylate waterproof coating which can be used for high-speed railway bridge decks and expressway roadbeds and a preparation method thereof. Background technique

[0002] With the rapid development of the country's economy, the current road and rail transportation network can no longer meet the growing transportation demand. In January 2004, the State Council deliberated and approved the national "medium and long-term railway network plan". In order to achieve the national railway network development goal of 100,000 kilometers in operation by 2020, it is planned to build about 16,000 kilometers of ordinary railway lines and 12,000 kilometers of new lines The above "four vertical and four horizontal" railway rapid passenger transport channels and three intercity rapid passenger transport systems. These passenger dedicated lines belong to the high-speed railway system, and t...
