▎ 摘　　要

NOVELTY - Low density aqueous workshop primer comprises a component A and component B. The component A comprises an aqueous silicate solution and an aqueous graphene slurry. The component B comprises a zinc powder, a filler and an organic modified zinc phosphate salt. USE - Used as low density aqueous workshop primer. ADVANTAGE - The low density aqueous workshop primer: has simple preparation technique which does not need to continuously stir and easily block the spray gun thus solves the problems of inconvenience in the construction of aqueous workshop primer; is economical; and has wide market application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing low density aqueous workshop primer, comprising (i) mixing the aqueous silicate solution and aqueous graphene slurry to obtain component A and mixing the zinc powder, the filler and the organic modified zinc phosphate salt to obtain the second component; and (ii) mixing the component A and B component.
