Problems solved by technology

[0003] Most of the current waterproof coatings are made of petroleum and rubber raw materials. With the depletion of petroleum resources, it is inevitable that raw materials will be tense or even unable to be guaranteed.
At the same time, the existing waterproof materials may also cause harm to the environment and the human body, such as polyurethane waterproof materials

Abstract

The invention discloses a construction waste anticorrosive coating and a preparation method thereof, and belongs to the technical field of anticorrosive coating. The waterproof paint is formed by mixing a powder material part and a liquid material part according to the proportion of 6: 5; the powder material part is prepared from the following components in parts by weight: 65 to 75 parts of ground construction waste, 10 to 15 parts of ordinary Portland cement or white cement, 8 to 15 parts of heavy calcium powder and 1 part of other modified materials; the liquid material part is prepared from the following components in parts by weight: 90 to 95 parts of acrylic emulsion, 3 to 5 parts of water-based pigment and 1 to 3 parts of other modified materials; the other modified materials in the powder material part are universal waterproof coating modified materials, and the other modified materials in the liquid material part are materials for adjusting the performance of the emulsion. The solid construction waste is used for replacing natural quartz sand and partial filler in the current waterproof coating, so that the comprehensive utilization of the construction waste is realized, the existing mineral resources are effectively protected, the energy is saved, the environment is protected, and good economic benefits and wide market prospects are realized.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, and in particular relates to a water-based construction waste waterproof coating and a preparation method thereof. Background technique [0002] In recent years, in some areas, in terms of urban planning, industrial layout, and infrastructure construction, insufficient attention and consideration have been paid to the reduction, recycling, utilization, and disposal of solid waste, which has seriously affected the sustainable development of the urban economy and society. Coupled with the strengthening of the implementation of environmental protection policies, "garbage siege" has become a headache for the governments of many cities and a problem for the masses. How to turn waste into treasure and solve the problem of "garbage siege" is imminent to take the road of industrialization of construction waste recycling. [0003] Most of the current waterproof coatings are made of petroleum ...
