Abstract

The invention provides a preparation method of liquid rubber asphalt water-proof paint and relates to a preparation method of water-proof paint. The preparation method provided by the invention is a preparation method of a rubber asphalt emulsion by taking a non-ionic surfactant as an emulsifying agent. The preparation method comprises the following steps: 1, preparing a non-ionic reclaimed rubber emulsion from the following components in parts by weight: 100 parts of reclaimed rubber, 0-2 parts of stabilizing agent, 0-8 parts of non-ionic emulsifying agent 1, 0-2 parts of non-ionic emulsifying agent 2 and 100 parts of water; 2, preparing a non-ionic asphalt emulsion from the following components in parts by weight: 100 parts of 70# petroleum asphalt, 0-2 parts of non-ionic emulsifying agent 1, 0-1 part of non-ionic emulsifying agent 2, 0-1 part of stabilizing agent and 100 parts of water; and 3, preparing the liquid rubber asphalt water-proof paint from the following components in parts by weight: 70-80 parts of non-ionic reclaimed rubber emulsion, 20-30 parts of chloroprene rubber latex and 100 parts of non-ionic asphalt emulsion. The liquid rubber asphalt water-proof paint prepared by using the method can be widely used in projects with high thermal resistance requirement and railway, highway, municipal bridges and building waterproof and anticorrosive projects which have high crack resistance requirements.

Description

Technical field: [0001] The invention relates to a preparation method of waterproof paint. Especially the preparation method of liquid rubber asphalt waterproof coating. It is a manufacturing method of rubber asphalt emulsion with non-ionic surfactant as emulsifier. Background technique: [0002] Mixing various rubbers in asphalt can overcome the shortcomings of high-temperature softening and low-temperature embrittlement of asphalt itself, and improve the tear resistance in winter, and no cracks will appear at low temperature -25°C; the anti-melt performance in summer is also improved. It is improved and does not soften at high temperature. For this reason, it is necessary to modify the petroleum asphalt in order to meet the needs of construction and municipal engineering. [0003] There are many ways to modify asphalt. At present, rubber, resin and mineral fillers are commonly used for modification. Among them, rubber is an important modified material for asphalt.
