Abstract

The invention discloses a graphene antibacterial electrostatic spraying timber priming paint for reducing sheet material VOCs release and a production method thereof. The priming paint comprises an aqueous resin adhesive, a wetting dispersant, an antifreezing agent, a thickening agent, an antifoaming agent, an anti-VOCs functional filling material, an antibacterial electrostatic slurry, a pH conditioning agent, a bactericide, a dry membrane antiseptic and water. The anti-VOCs functional filling material comprises active carbon, nano negative ion powder, a coupling agent and water. The antibacterial electrostatic slurry is obtained by dispersing graphene and nano silver. The priming paint uses the characteristics of high graphene conductivity, large specific surface area and large radius-thickness ratio, small addition amount of graphene enables mutual stacking after film forming of the priming paint, a compact membrane structure is formed, sheet material VOCs release is obstructed, and the electrostatic spraying requirement of the paint can be simultaneously reached, and the absorption effect of the active carbon and the decomposition of a low molecular organic matter by the negative ion powder are used, and the functions for enriching and decomposing VOCs can be achieved.

Description

technical field [0001] The invention relates to a wood primer, in particular to a graphene antibacterial electrostatic spray wood primer which reduces the release of VOCs from boards and a preparation method thereof, belonging to the technical field of surface treatment of wood boards and woodware. Background technique [0002] Since the 1990s, with the rapid development of the real estate industry and interior decoration materials, people have higher and higher requirements for the comfort and aesthetics of the living environment, and the interior decoration styles have become more diverse and humanized. However, due to the unqualified emission of harmful gases from indoor decoration materials and indoor furniture, and the excessive use of decoration materials, the problem of indoor pollution is becoming more and more serious. [0003] Indoor air quality is an old and new issue. As the indoor pollution problem becomes more and more serious, people's health is seriously affe...
