Abstract

The invention provides a waterproof paint for roads and bridges and a preparation method thereof. The preparation method comprises the following steps: emulsifying 15-20 parts of rubber material, 5-8 parts of polymer emulsion and 8-12 parts of resin material in an emulsifying machine at 60-70 DEG C to obtain a rubber latex emulsifier mixed solution; and mixing the obtained rubber latex emulsifier mixed solution with 60-80 parts of heavy-duty road asphalt, 1-3 parts of film-forming assistant and 8-12 parts of defoaming agent in the emulsifying machine at 120-130 DEG C. The waterproof paint for roads and bridges has the advantages of heat resistance, cold resistance, acid resistance, alkali resistance, high softening point, long service life, favorable waterproof and impervious effects, wide raw material sources, accessible raw materials and simple preparation method.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a road and bridge waterproof paint and a preparation method thereof. Background technique [0002] At present, the waterproof method of bridge structures in my country generally adopts road and bridge flexible material pavement systems, and the waterproof materials used are mainly SBS or APP (APAO) modified asphalt waterproof membranes or building waterproof coatings, such as polyurethane waterproof coatings, JS composite waterproofing paint etc. However, due to the special performance requirements of road and bridge waterproof coatings, for example, when the average thickness of the waterproof coating film is 1.2mm to 2mm, it can meet the requirements of repeated dynamic load and compression resistance of road bridges. The amount meets the need of no cracking to ensure waterproof requirements; at the same time, the waterproof layer should have good durability, and the service l...
