Problems solved by technology

The road surface dust suppressant is sprayed on the road surface to make dust and other particles bond into stable soil and land on the road surface. However, the dust suppression cycle of the dust suppressant is short and cannot suppress dust for a long time. It is necessary to continuously spray the dust suppressant on the road surface

Abstract

The invention discloses a colored building site dust raising inhibition material. The material is characterized by being prepared from the following raw materials in parts by weight: 0.3 to 0.8 part of nano cellulose fiber, 0.5 to 1.5 parts of pigment, 0.1 to 0.4 part of polyether modified amino-terminated water-soluble hyperbranched polyamide, 0.05 to 0.15 part of N-(trimethoxysilylpropyl)ethylenediamine triacetic acid sodium salt, 0.08 to 0.12 part of adenosine, 0.03 to 0.06 part of surfactant and 80 to 90 parts of water. The invention also discloses a preparation method of the colored building site dust raising inhibition material. The colored building site dust raising inhibition material disclosed by the invention is remarkable in dust suppression effect, long in dust suppression period, diversified in function, good in environmental adaptability, high in color fastness and uniform in dyeing.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a colored construction site dust suppression material. Background technique [0002] With the advancement of science and technology and the increasing demand for environmental resources, the deterioration of the human living environment is becoming a serious problem, among which dust pollution is the most intuitive and is becoming one of the most serious environmental problems. Life and social development have brought many disadvantages. Especially in recent years, there are many construction projects in our country, and dust from construction sites has become an important source of dust pollution. In addition to reducing air visibility, causing equipment wear and affecting plant growth, dust in construction sites can also induce a variety of infectious diseases and respiratory diseases. Therefore, the research on dust suppression materials for construction site...
