Abstract

The invention provides a rock soil curing agent and a preparation method thereof. The preparation method comprises the following steps: mixing 5-8 parts of PVC resin powder with 10-20 parts of ethanol and 10-20 parts of water, and uniformly stirring to obtain a mixed solution 1; slowly adding 1-2 parts of toluene, 1- 2 parts of ethylenediamine, 30-40 parts of isopropanol glycidyl ether and 1-2 parts of a naphthalene sulfonate formaldehyde polymer to 35-95 parts of strong acid, and uniformly stirring to obtain a mixed solution 2; and mixing the mixed solution 1 with the mixed solution 2 to obtain a mixed solution 3, adding 30-60 parts of gypsum powder into the mixed solution 3, and uniformly stirring to obtain the rock soil curing agent. The rock soil curing agent can be well applied to construct roadbeds of roads in order to greatly reduce the road construction cost and effectively solve the problems of soil discard, land occupation and the like; and additionally, raw materials required by the preparation of the rock soil curing agent have wide sources, are cheap and are easy to obtain, and the preparation method is simple, is easy to operate, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of road paving materials, in particular to a rock soil curing agent and a preparation method thereof. Background technique [0002] After mankind entered the 20th century, the level of science and technology has greatly improved, the scale of economic production has expanded rapidly, and the population has expanded extremely. The development and destruction of natural resources have also reached an astonishing degree, and the exhaustion of resources and energy has increased. Facing the situation of resource shortage and environmental change, people have to think about the sustainable development of social economy. [0003] In the construction of various highways in my country, especially the subgrade of high-grade highways, the upper base layer is mostly made of fly ash gravel or cement stabilized gravel structure layer to ensure that the quality of the road subgrade meets the design requirements. Due to the high req...
