Abstract

The invention discloses a macromolecule latex foamed product capable of degrading formaldehyde and TVOC (Total Volatile Organic Compound) and inhibiting germs and a preparation method. The preparationmethod comprises the following steps: titanium silver spray preparation: adding titanium dioxide and nano silver into water to prepare a titanium silver mixed solution; latex coating: coating a carrier material of a conveying belt with foamed latex; initial latex roasting: conveying the carrier material with the surface coated with the latex into a first oven; spray coating: spray coating the surface of the latex, which is initially roasted and is not formed, with the titanium silver mixed solution; product roasting and forming: conveying the carrier material which is sprayed and covered by the titanium silver mixed solution into a second oven to dry and to form a latex layer and a nano titanium silver coating layer on the surface of the carrier material. According to the preparation method disclosed by the invention, latex coating, spray coating and two-section type drying are utilized, so that nano titanium dioxide and nano silver can be organically combined with the latex foamed product, hazardous substances of formaldehyde, TVOC and the like can be degraded, germs are inhibited, and product application is enriched.

Description

technical field [0001] The invention relates to the technical field of latex foam products, more specifically, to a polymer latex foam product that degrades formaldehyde, total volatile organic compounds (TVOC) and inhibits germs and a preparation method thereof. Background technique [0002] Latex material has the characteristics of high elasticity, good air permeability, environmental protection, pure natural, comfortable and durable, shock absorption, etc., so it has been widely used in various daily products, such as sofa mattresses, pillows, mouse pads, seat cushions, women's underwear Various latex foam products or objects, but the existing latex foam products or objects have a single function and do not have the functions of degrading formaldehyde, TVOC and inhibiting germs. [0003] Studies have found that nano-scale titanium dioxide can oxidize and decompose harmful substances such as formaldehyde and toluene into carbon dioxide, water and organic acids under light ...
