Problems solved by technology

This kind of antifreeze is made of surfactant and other components, which has serious corrosion to metal, so it has been used for a long time. One is made of urea compound sodium nitrite as antifreeze component, and other fillers are added. This antifreeze The nitroso in the agent is a carcinogen, which is more harmful to the operation. In addition, the source of urea is tight, so the price is expensive and the cost is high.

Embodiment Construction

[0019] The present invention will be further described below by way of examples.

[0020] Process flow:

[0021] Get propionic acid sodium hydroxide and sodium oxide to carry out the neutralization reaction the sodium propionate and the former starch that the above-mentioned reaction makes. Fly ash, wood calcium, ABS, antirust additives, and triethanolamine are mixed in proportion and stirred. Dried, finally make the above-mentioned formula ratio (percentage by weight) of antifreezing agent to be: Sodium Propionate: Former Mingfen: Fly Ash: Wood Calcium ADS: Antirust Additive; Triethanolamine=35: 25: 25: 3: 1: 6.

Abstract

The present invention discloses the production process of antifreezer. The production process includes the reaction between low-carbon organic acid with metal oxide, hydroxide or carbonate at 50-80 deg.c to produce low carbon organic salt as the antifreezing component; adding early strength agent, early strength catalyst, additive, stuffing, water reducing agent, air entraining agent, rust inhibitor and other components, mixing and drying to form the antifreezer. The present invention has low production cost, no rustiness to steel bar, no toxicity, no smell and no harm to the operator.

Description

technical field [0001] The invention belongs to concrete antifreeze material and a production method thereof. Background technique [0002] The construction industry is generally constructed outdoors, and the outdoor temperature is above zero, but in winter, when the outdoor temperature is below zero, the concrete will freeze, so it will not be possible to construct. The antifreeze agent makes the freezing point of concrete drop, thus solving the difficulty of building construction in winter. There are two main types of antifreeze used at present: one is to use chlorine salt as the antifreeze component, and at the same time, compound yuanming is added. This kind of antifreeze is made of surfactant and other components, which has serious corrosion to metal, so it has been used for a long time. One is made of urea compound sodium nitrite as antifreeze component, and other fillers are added. This antifreeze The nitroso in the agent is a carcinogen, which is ...
