Embodiment 1

[0029] Taking the preparation of 100g black-and-white photo visualization strengthening agent as an example, it contains the following components in proportion by mass:

[0030]

[0031] The preparation method of the above-mentioned black-and-white photo display reinforcing agent is as follows:

[0032] Step 1: Prepare Ethylcellulose Solution

[0033] Get 4.0g ethyl cellulose and join in the round bottom flask that fills 76.0g banana water, and put stirring bar in it, put the round bottom flask in the electric heating mantle with magnetic stirrer, adjust the temperature of electric heating mantle At 120°C, stir with a magnetic stirrer, heat and reflux for 2 hours, stop heating and reflux until the ethyl cellulose is completely dissolved, and prepare a banana aqueous solution of ethyl cellulose with a mass concentration of 5%.

[0034] Step 2: Prepare vinylidene fluoride-chlorotrifluoroethylene copolymer solution

[0035] Dissolve 0.5 g of vinylidene fluoride-chlorotrifluo...

Abstract

The invention relates to a black and white photo development reinforcing agent which is prepared by mixing banana oil solution of ethyl cellulose with nanometer silicon dioxide, banana oil solution of vinylidene fluoride-chlorotrifluoroethylene copolymer, di(1,2,2,6,6-pentamethyl-4-piperidyl)sebate and diisooctyl phenyl phosphate according to certain mass proportions. The black and white photo development reinforcing agent is mildew-proof, waterproof and acid-proof and has the properties of strong anti-aging capability, strong adhesive force and high hardness; the original appearance of seriously or slightly fuzzy or faded black and white photos can be revealed; the stability can be kept; various mechanical strength and mechanical properties of the photos can be effectively improved; and long-term storage of historical relics is more benefited.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a reinforcing agent capable of displaying blurred and faded black-and-white photos. Background technique [0002] Black and white photos are an important type of modern archives. There are a large number of precious photos in the archives system of our country, which record many major historical events and environmental changes. Relics, buildings, cultural relics, and paper documents are mutually confirmed and irreplaceable. display content. Black-and-white images not only carry huge social information, but are also a special type of archive that showcases the distinctive scientific and technological connotations of this major invention. However, due to the characteristics of the materials it is made of and the influence of the environment, a series of serious diseases have occurred in black and white photos during the preservation process, such as image fading and...
