Preparation method of environment-friendly degradable building material

The invention discloses a preparation method of an environment-friendly degradable building material. In the prior art, most of the existing building materials are not easy to degrade, so that the recovery effect of the building material is not good, and the waste of the building material is easily caused so as to increase the cost; the existing degradable building materials are high in preparation cost and cannot be universally used; and the content control effect in the preparation process is poor, so that the degradable effect of the building materials is poor so as to reduce the working efficiency. According to the invention, by using a mixture of bamboo fibers, wood fibers, sepiolite, corn starch, rice sugar powder, talcum powder, paper pulp and an adhesive, the degradation effect ofthe building material is realized, so that the recovery effect of the building material is good; the raw materials are mixed according to a certain ratio so as to avoid the waste of the raw materials;and the materials are all
