Latex powder, hydroxypropyl methyl cellulose, wood fibre, polypropylene fibre and water composition；Preparation method is graphene oxide dispersion
Yu Shuizhong；Then by glass microballoon, cement, powdered whiting, latex powder, hydroxypropyl methyl cellulose, wood fibre and poly- third
The mixed powder of alkene fiber is added in graphene oxide dispersion；It at the uniform velocity stirs 5 ~ 10 minutes, obtains graphite oxide alkenyl guarantor
Warm mortar.In addition, Wu Yuyou et al. has invented a kind of inexpensive graphene oxide mortar and preparation method thereof（Chinese invention is special
Sharp application number 201711373540.4）, include the raw material of following mass fractions：450 parts of cement, 180 parts of water, natural river sand 1350
Part, 0.9 part of high-efficiency water-reducing agent of poly-carboxylic acid, 16.9 parts of graphene oxide solution raw material；The preparation method packet of graphene oxide mortar
The proportioning of raw material is included, the mixing of raw material, pours, be molded and conserve, preparation method is simple to operation；The oxygen prepared using the invention
Graphite alkene mortar, by the mixing ratio of optimizing raw material, and adds graphene oxide solution raw material, not only meets made of making
Concrete meets intensity requirement, and price is low.
As it can be seen that the cement-base composite material of the addition derivatives such as graphene or graphene oxide in the prior art, exists
Graphene is easily reunited in cement system, can not be evenly dispersed, and then affects the effect etc. of the modified cement composite material of enhancing,
Constrain graphene building field application development.
