A kind of sterilizing and heat-insulating reflective material for farms and its preparation method

Abstract

The invention provides an antibacterial heat-insulation reflecting material for a livestock farm. By releasing antimicrobial activity through self-cleaning property of polytetrafluoroethylene and synergistic photosensitivity of polydopamine-benzophenone-polyphenol acid, the antibacterial effect is achieved while the heat insulation effect is achieved. According to the technical scheme, the antibacterial heat-insulation reflecting material for the livestock farm comprises a flame retardant bubble layer and an antibacterial cleaning layer; a first flame retardant rubber layer, a first aluminum foil layer and an aerogel layer are sequentially arranged on one side of the flame retardant bubble layer, and a second flame retardant rubber layer, a second aluminum foil layer and the antibacterialcleaning layer are sequentially arranged on the other side of the flame retardant bubble layer; the antibacterial cleaning layer is a modified polytetrafluoroethylene layer with the surface depositedwith polydopamine-benzophenone-polyphenol acid active sites. The invention further provides the preparation method of the antibacterial heat-insulation reflecting material for the livestock farm, andmultilayer functional components can be effectively combined together.

Description

【Technical field】 [0001] The invention relates to the field of thermal insulation materials, in particular to a nanocomposite thermal insulation material and a preparation method thereof. 【Background technique】 [0002] In recent years, under the call of promoting agriculture through science and technology, my country's modern aquaculture industry has developed rapidly. In the breeding industry, the shed is the biggest problem that plagues the majority of farmers in our country. The simple shed does not keep warm in winter and does not insulate in summer. In order to maintain the healthy growth of animals, it needs to invest a lot of energy to maintain the basic temperature. Standard sheds require a large amount of fixed capital investment in the early stage, which has high risks and low returns. [0003] Aluminum foil bubble heat insulation material uses high-purity micro-aluminum coated with nano-materials as the upper and lower surface layers, and uses high-strength, low...

Problems solved by technology

However, although this material can keep warm and insulate, it has poor air permeability, and pesticide residues are easy to accumulate on the roof of the house. Over time, it will produce mildew, breed bacteria and release toxic gases, threatening and affecting the health and safety of seedlings.
