Antifreezing paste and preparation method

Abstract

The invention discloses an anti-freezing paste and a preparation method thereof and relates to a paste and a preparation method thereof. The invention solves the problems that: in the prior art, the viscosity, bonding degree and waterproof performance of the paste are bad, the paste is easy to be frozen up and concreted at low temperature, and a low-temperature glue has high manufacturing cost and is added with toxic substances such as oxymethylenes and the like. The anti-freezing paste is prepared by halogen powder, clean water, flour, table salt, white sugar, a pearl glue and ammonium hydrocarbonate. The preparation method includes: mixing the halogen powder, the clean water, the flour, the table salt, the white sugar and the pearl glue together, stirring and heating till boil, then adding the ammonium hydrocarbonate, keeping on heating and stirring, lowering to room temperature after boiling, and obtaining the anti-freezing paste. The viscosity of the anti-freezing paste is increased by 10 percent to 60 percent, and the bonding degree is increased by 20 percent to 40 percent. When being used outdoor in winter, the anti-freezing paste can not be frozen up or concreted in 24 hours under enclosed status. And toxic substances such as oxymethylenes and the like are not added and the manufacturing cost is low.

Description

Technical field [0001] The invention relates to a paste and a preparation method. Background technique [0002] At present, the adhesives sold on the market are mainly divided into two types: paste and glue. The paste has poor viscosity, cohesiveness and water resistance; it is easy to freeze and solidify even when used outdoors in winter in northern China (-20~-35℃), making it impossible to use it outdoors in winter; and the low temperature environment causes the existing The bonding performance of the paste is lost, the bonding force is reduced, and the normal application is affected. Therefore, measures such as heat preservation of the paste are required, which causes inconvenience; the glue cannot be used under the condition of -20~-35℃, and it can be used by adding antifreeze Improve its antifreeze performance, but it leads to high production costs and reduced glue adhesion. In addition, antifreeze ingredients are chemical substances and formaldehyde is released, which not o...
