Formaldehyde scavenger with pure natural plant extract and method for preparing formaldehyde scavenger

Abstract

The invention discloses a formaldehyde scavenger with pure natural plant extract and a method for preparing the formaldehyde scavenger, and belongs to the field of technologies for biologically extracting natural plants. The formaldehyde scavenger comprises, by weight, 20%-40% of Ocotea spp. extract liquid, 10%-40% of cinnamomum camphora leaf extract liquid, 10%-20% of herba houttuyniae extract liquid, 10%-20% of semen myristicae extract liquid, 10%-20% of platycladus orientalis extract liquid, 5%-20% of radix glycyrrhizae extract liquid and 5%-20% of folium eucalypti extract liquid. The weights of the Ocotea spp. extract liquid, the cinnamomum camphora leaf extract liquid, the herba houttuyniae extract liquid, the semen myristicae extract liquid, the platycladus orientalis extract liquid, the radix glycyrrhizae extract liquid and the folium eucalypti extract liquid is 100%. Processes for preparing plant extract liquid include utilizing water as an extracting agent; cooking plants, cooling the plants until the temperatures of the plants reach the normal temperature and carrying out filtering, closed fermentation and distillation. The formaldehyde scavenger and the method have the advantages that formaldehyde, harmful gas such as benzene and dimethylbenzene and undesirable odor can be efficiently decomposed by the formaldehyde scavenger prepared by the aid of the method, and the formaldehyde scavenger further has antibacterial, sterilization, deodorization and antistatic functions; the shortcomings of secondary pollution due to existing formaldehyde scavengers prepared from chemical reagents and existing formaldehyde scavengers mainly with chemical reagents and certain added plant extract liquid, poor formaldehyde scavenging effects and short shelf lives can be overcome.

Description

technical field [0001] The invention belongs to the technical field of natural plant biological extraction, and in particular relates to a formaldehyde scavenger composed of pure natural plant extracts and a preparation method thereof. Background technique [0002] Indoor decoration uses a lot of glued materials containing chemical components, which contain a lot of volatile toxic compounds, especially benzene, xylene, and formaldehyde, which seriously pollute the indoor air and endanger the health of people, especially children. In order to solve this problem, researchers have developed many varieties of formaldehyde scavengers in recent years, but the effects are not satisfactory. The formaldehyde scavengers sold on the market mainly include chemical reaction formaldehyde scavengers and formaldehyde scavengers with plant extracts as the main component and synthetic compounds added. The chemical reagents involved in the chemical reaction formaldehyde scavenger mainly inclu...
