Problems solved by technology

[0006] For the above two types of formaldehyde pollution, formaldehyde scavenger products currently on the market usually eliminate residual formaldehyde according to physical adsorption or chemical adsorption treatment methods, but there will be the following technical defects: (1) using physical adsorption, such as activated carbon, bamboo charcoal, etc. , the adsorption capacity is limited, and it is inconvenient to use, and often needs to be replaced, causing secondary pollution; (2) using chemical adsorption, although the treatment effect of formaldehyde is good, but the compound added in the scavenger is more toxic and not environmentally friendly

Abstract

The invention belongs to the technical field of formaldehyde scavengers and in particular relates to a compound protein formaldehyde scavenger as well as a preparation method and application of the compound protein formaldehyde scavenger. The compound protein formaldehyde scavenger comprises the following raw materials: 10-20% of plant proteins, 0.2-1.0% of acidic proteinase, 10-20% of animal proteins, 0.2-1.0% of alkaline protease, 0.2-1.0% of oxidant, 0.2-1.0% of decolorizing agent, 0.2-2.0% of penetrating agent, 5-15% of humectant and 40-70% of water. The compound protein formaldehyde scavenger contains a great amount of amino acid derivatives, biological enzymes and the like, the amino acid derivatives react with formaldehyde, the compound protein formaldehyde scavenger is good in chemical stability, nontoxic, tasteless and nonvolatile and incapable of generating secondary pollution due to certain antibacterial property, and the biological enzymes and the like adsorb formaldehyde to play a clearing role; and the compound protein formaldehyde scavenger is relatively low in raw material cost, simple and convenient in preparation method, wide in application range, green, environment-friendly and higher in formaldehyde removal efficiency due to the combination of the plant proteins and the animal proteins.

Description

technical field [0001] The invention belongs to the technical field of formaldehyde scavenger, and in particular relates to a composite protein formaldehyde scavenger, its preparation method and application. Background technique [0002] Formaldehyde is a colorless, soluble, irritating gas. It is recognized as a highly toxic substance. Formaldehyde can be absorbed through the respiratory tract, and damage the body by increasing tissue active oxygen, lipid peroxidation, and affecting the body's immune system, causing bronchial asthma, etc.; formaldehyde also has a stimulating effect on the skin and mucous membranes, which can cause allergic dermatitis, Pigmentation, skin necrosis, etc.; In addition, formaldehyde is also highly carcinogenic and can cause nose cancer, blood cancer, etc. Moreover, high concentrations of formaldehyde are harmful to the respiratory system, nervous system, immune system, and liver. It can be seen that formaldehyde, especially high-concentration f...
