Problems solved by technology

[0002] In the severe winter, the snow on the road is not easy to melt, and the melted snow water and the snow flakes formed after being rolled by the car bring inconvenience to people's traffic, and make the braking distance of motor vehicles driving on the road at high speed Elongated, and the wheels are easy to slip, which increases the frequency of traffic accidents
In order to reduce the occurrence of traffic accidents and increase the safety of vehicles, people sprinkle various agents that can promote the melting of ice and snow on the road, such as sodium chloride, calcium chloride and other solubilizers, but these solubilizers are used in large quantities. At the same time, people will worry that vehicles, bridges and road facilities will be corroded, which will reduce their service life; at the same time, snow water containing solubilizers will flow into lakes and rivers, which will pollute water sources, affect the environment, and even cause plant death in severe cases

experiment example 1

[0017] In the general sodium chloride raw material, the moisture is 4-6%, exists in the form of free water, by weight, get 250 parts of sodium chloride with a water content of 4-6%, in a drying oven with an outlet temperature of 200-240 degree, time 8-12 minutes, until the water content is below 2.5%, preferably below 1%, 150 parts of magnesium chloride 6 hydrate and 50 parts of calcium chloride 2 hydrate; sieve the above raw materials through a rotary sieve to obtain the particle size The material is 1mm-5mm, and the material that does not meet the particle size requirements is crushed by the crushing process and then sieved.

[0018] Select 60 parts of sodium chloride, 30 parts of magnesium chloride, and 5 parts of calcium chloride after the above screening, and mix them on an automatic mixer to obtain an antifreeze composition, and the product is marked as A.

experiment example 2

[0020] Select 40 parts of sodium chloride, 45 parts of magnesium chloride, and 15 parts of calcium chloride after the above screening, and mix them on an automatic mixer to obtain an antifreeze composition, and the product is marked as B.

experiment example 3

[0022] Select 50 parts of sodium chloride after the above screening, 30 parts of magnesium chloride, 10 parts of calcium chloride, and 2 parts of a mixture of trisodium citrate and magnesium sulfate in parts by weight of 1:1 or trisodium phosphate and magnesium sulfate in parts by weight The mixture of 1: 1 is mixed on an automatic mixer to obtain an antifreeze composition, and the product is marked as C.

[0023] In experiment 1, three snow fields with the same temperature of 1 square meter were selected, and the thickness of the snow layer was 5cm, and the snow melting experiment was carried out. The experimental results are as follows:

[0024]

[0025] In experiment 2, three iron plates of 1 square meter were selected to carry out the corrosion resistance experiment. The experimental results are as follows:

[0026]

[0027] Experiment 3, choose an asphalt road covered with ice and snow with the same road conditions, sprinkle product C on one section, and not sprinkl...

Abstract

The present invention discloses one kind of antifreezing agent composition and its production process. The antifreezing agent composition is produced with sodium chloride 40-60 weight portions, calcium chloride 5-15 weight portions, magnesium chloride 30-45 weight portions and corrosion inhibiting additive 1-3 weight portions. The corrosion inhibiting additive is mixture of trisodium citrate or trisodium phosphate and magnesium sulfate in the equal ratio. The production process includes the steps of sorting material, drying, sieving and mixing. The antifreezing agent composition is spread in road with ice and snow and can thaw ice and snow effectively to ensure traffic safety.

Description

technical field [0001] The present invention relates to an antifreezing agent composition for suppressing slipping and shortening the braking distance of a vehicle by spreading on an ice or snow surface, and a method for producing the same. Background technique [0002] In the cold winter, the snow on the road is not easy to melt, and the melted snow water and the snow flakes formed after being rolled by the car bring inconvenience to people's traffic, and make the braking distance of motor vehicles driving on the road at high speed Lengthened, and the wheels are easy to slip, which increases the frequency of traffic accidents. In order to reduce the occurrence of traffic accidents and increase the safety of vehicles, people sprinkle various agents that can promote the melting of ice and snow on the road, such as sodium chloride, calcium chloride and other solubilizers, but these solubilizers are widely used At the same time, people will worry that vehicles, bridges and roa...
