The invention belongs to the field of lightning protection materials and particularly relates to a novel lightning protection material prepared from graphene and applied to multiple fields, an adoptedassistant and a preparation method of the novel lightning protection material. According to the technical scheme, the novel lightning protection material is prepared from the following components inparts by weight: 100-200 parts of cement, 90-160 parts of sand, 50-120 parts of crushed stone and 5-30 parts of the assistant. Metal use amount can be reduced, construction steps are reduced, performance of the material is better in presence of water, corrosion is avoided, service life is long and cost is low. The material is widely applied and part of typically applications are as follows: preparation of lightning protection members, lightning protection foundations, grounding foundations and the like of facilities including an electric tower, a bridge, a railway, a high-speed rail, an airport, a signal tower, a chimney, a high-rise building and the like.
