The invention discloses a spray-filmed
composite material for fruit and vegetable or
crop bagging, as well as preparation and application thereof, and belongs to the field of
functional composite materials and fruit and vegetable or
crop bagging. The material is prepared from the following components in parts by
mass: 5-30 parts of a film-forming substance, 58-94 parts of a dispersing agent, 1-10 parts of a
pesticide-loading reinforcing material, 0.1-2 parts of an
insect-proofing
disease-resisting agent and 0-0.1 part of dye. The material has multiple colors and excellent
insect-proofing
disease-resisting performance, can be adhered to the surface of
fruits and vegetables or crops to form a film to achieve the aim of bagging, does not influence growth of the
fruits and vegetables or crops, does not have toxic or
side effect, and can sustainably release
insect-proofing
disease-resisting substances. The material is simple in preparation method and low in
raw material cost, can be used for replacing
pesticide to solve the problem of
pesticide residue, can be used for producing green organic foods, has
long acting duration for 1-3 months, and can be used for preventing insects and resisting diseases for fruits, vegetables, crops, flowers, woods and the like.
