preparation example Construction

[0032] Further, as figure 1 Shown, the present invention also provides a kind of preparation method of magnesium phosphorus anchor glue, it may further comprise the steps:

[0033] S1. Take 80-120 parts of dead-burned magnesium oxide and 40-60 parts of ammonium dihydrogen phosphate for dry mixing to obtain a dry material mixture;

[0034] S2. Add 10 to 20 parts of water to the dry material mixture and stir to obtain a wet material mixture;

[0035] S3. Add 40-60 parts of ammonium dihydrogen phosphate to the wet material mixture, stir and mix to obtain the magnesium phosphorus anchoring glue.

[0036] Wherein, the acid-base reaction mechanism of preparing above-mentioned phosphorus-magnesium anchor glue is:

[0037] First stage, dissolution of the phosphate component. When magnesium phosphate cement is mixed with water, the phosphate component that is easily soluble in water dissolves first, releasing PO 4 3- 、H + , forming a low pH phosphate aqueous solution.

Embodiment 1

[0075] A magnesium phosphorus anchoring glue is composed of 100kg of dead-burned magnesia, 100kg of ammonium dihydrogen phosphate and 15kg of water. The specific preparation method includes the following steps:

[0076] S1. Put 100kg of dead-burned magnesia and 50kg of ammonium dihydrogen phosphate into a mixer for dry mixing for 1min to obtain a dry material mixture;

[0077] S2. Add 15 kg of water to the dry material mixture and stir for 1 min to obtain the wet material mixture;

[0078] S3. Add 50 kg of ammonium dihydrogen phosphate to the wet material mixture and stir for 2 to 3 minutes to obtain phosphorus and magnesium anchor glue.

Embodiment 2

[0080] A magnesium phosphorus anchor glue is composed of 100kg of dead-burned magnesium oxide, 120kg of ammonium dihydrogen phosphate and 20kg of water, and the specific preparation method is the same as that of Example 1.

Abstract

The invention relates to the technical field of building materials, and especially relates to a phosphorus and magnesium anchoring glue and a preparation method thereof. The glue comprises, by weight,80-120 parts of dead-burned magnesia, 80-120 parts of ammonium dihydrogen phosphate and 10-20 parts of water. The preparation method includes the following steps: S1, taking 80-120 parts of the dead-burned magnesia and 40-60 parts of ammonium dihydrogen phosphate, and performing dry mixing until uniformity in order to obtain a dry material mixture; S2, adding 10-20 parts of the water to the dry material mixture, and performing stirring and mixing until uniformity in order to obtain a wet material mixture; and S3, adding 40-60 parts of the ammonium dihydrogen phosphate to the wet material mixture, and performing stirring and mixing until uniformity in order to obtain the phosphorus and magnesium anchoring glue. The phosphorus and magnesium anchoring glue has can firmly bond to steel and other metals, has an excellent reinforcement performance, no special requirements for anchoring or fixing parts, very low creep and shrinkage and good resistance to acid and groundwater corrosion, is suitable for rapidly anchoring post-anchor bolts (reinforcements) and anchor poles of concrete structures, and has excellent application prospects in the fields of rapid repairing, first-aid repairing and reinforcement.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a phosphorus-magnesium anchor glue and a preparation method thereof. Background technique [0002] With the continuous development of economic construction, road engineering, as the link of economic construction, is playing an increasingly important role. However, an important problem facing road engineering construction is the aging of anti-collision walls. Many expressways have been built and put into use for more than 20 years since the 1980s and 1990s. Due to the early construction of highways, the anti-collision performance of concrete anti-collision walls has declined due to natural aging of concrete and road surface reconstruction. Repairs and reinforcements to the crash walls of the highway are required. When repairing and strengthening, it is necessary to plant bars on the concrete structure of the original anti-collision wall and then pour concrete. When ins...
