Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blasting beads, and particularly relates to a blasting bead with anti-freezing performance and a preparation method thereof. BACKGROUND

[0002] When the blasting beads are stored for a long time in winter or cold environment, a large number of quality problems such as bubbles, breakage and concave may occur, which causes the blasting beads to be difficult or impossible to use. The main reason for the quality problems of the blasting beads is that the anti-freezing performance of the blasting beads is poor. The volume of the blasting bead core liquid changes (thermal expansion and cold contraction) when the temperature changes, but the blasting bead wall material cannot accompany the thermal expansion and cold contraction of the core liquid. When the temperature is low, the volume of the blasting bead core liquid is reduced, the volume of the wall material is unchanged, and therefore the gas fills the gap to form bubbles. The internal and external pressure of the blasting bead is different, and the gas gradually flows outward over time to form a concave. When the temperature changes from low temperature to normal temperature, the volume of the core liquid expands, and the blasting beads with small breakage pressure are easily broken.

[0003] The conventional solution is to take anti-freezing measures for the blasting beads, that is, to increase some physical warm-keeping measures for the blasting beads during transportation and storage, such as wrapping the blasting beads with some warm-keeping materials, controlling the temperature of the storage environment and the like. This method cannot fundamentally solve the quality problems of the blasting bead products, but only slows down or reduces the probability of the quality problems.

[0004] Therefore, it is urgent to provide a blasting bead with anti-freezing performance and a preparation method thereof. SUMMARY

[0005] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides a blasting bead with anti-freezing performance and a preparation method thereof. The wall material of the blasting bead achieves synchronous thermal expansion and cold contraction with the core liquid, so that the anti-freezing performance is improved, and the appearance failure rate of the blasting bead after being stored at minus 30 DEG C for one month (30 days) is less than 1 / 10,000 (under the same conditions, the appearance failure rate of the blasting bead without anti-freezing agent after being stored at minus 30 DEG C for one month is 12.5 / 10,000, and the appearance failure rate of the blasting bead with anti-freezing agent under the same conditions is about 6 / 10,000).

[0006] The inventive concept of the present application is that by adjusting the formula of the blasting bead production, the anti-freezing performance of the blasting bead is improved by adding a second colloid and an anti-freezing agent in the raw material formula of the wall material and adding the anti-freezing agent in the raw material formula of the core material, and the adaptability of the blasting bead wall material to environmental changes is improved. The blasting bead wall material achieves synchronous thermal expansion and cold contraction with the core liquid. When the environmental temperature changes, the blasting bead wall material expands and contracts with the volume increase and decrease of the core liquid. In this way, the blasting bead is not easy to produce bubbles and breakage, and the anti-freezing performance of the blasting bead itself is improved. The breakage pressure of the blasting bead is strengthened, which can further prevent the blasting bead from being broken when the volume of the core liquid expands from low temperature to normal temperature and the breakage pressure of the blasting bead is small.

At this time, the peak value of the downward pressure is read, which is the pressure resistance of the burstable balloon, i.e. the breaking pressure. 100 burstable balloons are detected each time, and the average value is calculated, which is kgf.
