Problems solved by technology

It is well known that a large amount of urea-formaldehyde glue is used in the production process of man-made boards, resulting in serious release of free formaldehyde, which pollutes the human body and the surrounding environment seriously, and seriously affects people's health. Long-term exposure to formaldehyde may lead to leukemia.

Embodiment 1

[0010] Weigh the following raw materials according to the following weight: 80 grams of glycine, 40 grams of adipic hydrazide, 610 grams of zeolite, 50 grams of zinc chloride, 150 grams of zinc sulfate, 70 grams of tourmaline powder, 0.032 grams of sodium ferrocyanide, trichloride 0.023 grams of iron, and then put the weighed raw materials into the mixer, and stir with the mixer until they are uniformly dispersed to obtain the additive.

[0011] Add 40 grams of the above additives to 1 kg of finished white latex, stir well, and the white latex will turn into light blue latex, which is the color-changing white latex.

Embodiment 2

[0013] Weigh the following raw materials according to the following weight: 70 grams of glycine, 50 grams of adipic hydrazide, 580 grams of zeolite, 40 grams of zinc chloride, 200 grams of zinc sulfate, 60 grams of tourmaline powder, 0.030 grams of sodium ferrocyanide, trichloride 0.020 g of iron, and then add the weighed raw materials into the mixer, and stir with the mixer until they are uniformly dispersed to obtain the additive.

[0014] Add 50 grams of the above additives to 1 kg of finished white latex, stir well, and the white latex will turn into a light blue latex, and the discoloration white latex will be obtained.

Embodiment 3

[0016] Weigh the following raw materials according to the following weight: 90 grams of glycine, 30 grams of adipic hydrazide, 600 grams of zeolite, 60 grams of zinc chloride, 140 grams of zinc sulfate, 80 grams of tourmaline powder, 0.033 grams of sodium ferrocyanide, trichloride 0.025 grams of iron, and then put the weighed raw materials into the mixer, and stir with the mixer until they are uniformly dispersed to obtain the additive.

[0017] Take 60 grams of the above additives and add it to 1 kg of finished white latex, stir well, and the white latex will turn into light blue latex, that is, the color-changing white latex is obtained.

Abstract

The invention discloses a white emulsion additive. The white emulsion additive is a mixture consisting of the following components in parts by weight: 70-90 parts of glycine, 30-50 parts of adipic dihydrazide, 500-700 parts of zeolite, 40-60 parts of zinc chloride, 100-200 parts of zinc sulfate, 60-80 parts of electric mountain flour, 0.03-0.033 part of sodium ferrocyanide and 0.02-0.025 part of ferric trichloride. The invention further discloses a preparation method of the white emulsion additive. The preparation method comprises the steps of adding raw materials into a stirrer, and stirring until the raw materials are uniformly scattered. The white emulsion additive, disclosed by the invention, has the advantages that the application range is wide, anions which are beneficial for human health can be chronically released, meanwhile, the release of free formaldehyde in an operating environment or a bonding plate can be effectively reduced, the effect is stable and remarkable, and the secondary pollution is avoided; and preparation and application processes are simple.

Description

technical field [0001] The invention relates to a white latex additive and a preparation method thereof. Background technique [0002] With the improvement of people's material life, home decoration is becoming more and more common, which leads to the extensive use of man-made panels in the decoration process, especially the increasing shortage of natural wood, which leads to an increase in the use of man-made panels. It is well known that a large amount of urea-formaldehyde glue is used in the production process of artificial boards, resulting in serious release of free formaldehyde, which pollutes the human body and the surrounding environment seriously, and seriously affects people's health. Long-term exposure to formaldehyde may lead to leukemia. In addition, white latex (PVAC), that is, polyvinyl acetate or modified polyvinyl acetate, is commonly used in furniture production and home decoration. Therefore, if the properties of white latex are modified, the free formalde...
