Abstract

The invention discloses a composite material capable of releasing volatile substances persistently and a preparation method thereof. The composite material is prepared from the following main components in parts by weight: 10-50 parts of aqueous resin, 50-180 parts of natural fiber, 3-8 parts of water-solubility hardening agent, 8-15 parts of phase transfer catalyst, 50-150 parts of filler, 2-9 parts of volatile substance and 100-200 parts of water. The invention uses the natural fiber and common high molecular materials as carriers of the volatile substances, has simple preparation and low production cost and can be decomposed directly in a natural state.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a composite material capable of sustainably releasing volatile substances and a preparation method thereof. Background technique [0002] Among the volatile substances, essential oils can give off a pleasant smell, but the simple use of essential oils is easy to volatilize, and the fragrance cannot last; similarly, the active ingredients of repelling (killing) insects also have the problem of easy volatilization and long-lasting drug effect. In order to prolong the action time of essential oils and insect repelling (killing) active ingredients, the existing method is to use special polymer material carriers to reduce the volatilization of volatile substances, such as making mosquito repellent patches and mosquito repellent crystal jelly, etc., but its Not only is the production complicated and the cost is high, but also the polymer materials used in large q...
