Description

Terahertz coupling anion material energy-saving card sheet and production method thereof
Technical Field
The invention belongs to the technical field of functional sheets, and particularly relates to a terahertz coupling anion material energy-saving card sheet and a production method thereof.
Background
Energy conservation and emission reduction are basic national policies and are the permanent subjects of human social development, automobile fuel saving and electric appliance power saving are the most intuitive, outstanding and important fields of energy conservation and emission reduction benefits, and as for automobile fuel saving, a plurality of technical products are provided, but the technical products are fewer and have convenient application, stable performance, practicability and reliability.
Patent CN201610085914.1 discloses a nano negative ion electricity/fuel saving card, which is prepared by mixing 80 parts of negative ion powder with the particle size of 200 nm, 5 parts of tourmaline powder with the particle size of 20 nm, 10 parts of far infrared powder with the particle size of 55 nm, 3 parts of starch adhesive and 2 parts of dicumyl oxide cross-linking agent, stirring at high speed to prepare negative ion slurry with stable viscosity, attaching the negative ion slurry between two layers of hard plastic plates, then hot pressing at high temperature of 120 ℃ for 5 minutes, cooling and preparing into a card.
In terms of the manufacturing process of the product of the above publication, 95 parts (80 parts of anion powder +5 parts of tourmaline +10 parts of infrared powder) of functional powder can ensure the generation of anions and far infrared rays, which should be realized, but the following problems are undoubtedly existed:
(1)3 parts of starch adhesive and 2 parts of cross-linking agent, especially the adhesive accounts for too little proportion in the solid film-forming material of the total composition to be formed or the adhesive strength can not be ensured after forming, just as if the cement is too little and the sand is too much.
(2) Starch is adopted to be bonded with two layers of plastic plates under hot pressing, the peeling strength is very low, common plastics are anti-sticking materials, the starch is difficult to obtain good adhesive force and is easy to crack, and the starch is a rewetting material and is easy to rewet when meeting water. The water in the pulping process cannot be volatilized but remains in the tabletting, so the water resistance is poor, and the application range of the product is limited.
(3) Because the intermittent working procedure of the hot press molding in the process of mixing the pulping and the two-layer plastic is adopted, a continuous and efficient production process is difficult to form in the production.
In view of the above, there is a need to develop an energy-saving card sheet made of terahertz coupled anion material to meet the above requirements.
