Insulating plate for manufacturing tea tray and manufacturing method thereof

Abstract

The invention discloses an insulating plate for manufacturing a tea tray, which is characterized by being prepared from, by weight, 150-200 g of formaldehyde, 150-160 g of phenol, 6.8-7.6 g of ammonia water, 40-80 g of cashew nut oil, 140-150 g of ethyl alcohol, 1-5 g of oleic acid, 2-8 g of hexamethylenetetramine, and 20-40 g of magnesium hydroxide. The insulating plate has the advantages that the defect that various materials difficultly meet the requirements on corrosion resistance, heat resistance, appearance attractiveness, price, environmental friendliness and the like is overcome, the insulating plate that has good properties and low price is provided, a preparation method of special modified phenolic resin adhesive is provided, and the preparation method is simple and easy to perform, low in environmental damage and low in cost.

Description

Technical field [0001] The invention relates to the field of bakelite tea trays, in particular to an insulating board for making tea trays and a manufacturing method thereof. Background technique [0002] With the diversification of the application of phenolic laminated cotton cloth board, the tea tray production industry needs a phenolic laminated cotton cloth board with excellent water resistance and exquisite appearance to replace some solid wood tea trays. The market can produce low-cost, environmentally friendly and excellent performance. Insulating materials are the main trend. [0003] At present, the tea tray industry in the market uses metal, stone, wood, etc. as the main raw materials, but the advantages and disadvantages of various tea trays are different, and in many cases they cannot meet customer satisfaction. Metal tea trays are basically not cracked or deformed, and they are clean and odorless, but they are not high-grade, and the atmosphere of tea tasting is great...

Problems solved by technology

[0003] At present, the tea tray industry in the market uses metal, stone, wood, etc. as the main raw materials, but the advantages and disadvantages of various tea trays are different, and in many cases it cannot satisfy customers

Metal tea trays are basically not broken and deformed, and clean and odorless, but they are not high-grade, and the atmosphere of tea tasting is greatly reduced; stone tea trays are not easy to absorb water, not easy to deform, and have a beautiful appearance, but the price of high-quality stone is too expensive; wooden tea trays meet the The atmosphere of drinking tea, but compared with other tea trays, the hardness, corrosion resistance, and water resistance of wooden tea trays are slightly inferior, and most of the wooden tea trays on the market today are imitations of miscellaneous wood, so be careful when buying
