Description
Technical Field
The invention relates to a shield foam additive easy to foam.
Background
For the foaming agent used in the earth pressure balance shield, the stability is a crucial performance, when the foaming agent is used in the shield process, according to the shield site construction, the foaming system sends out the foam, and the foam is mixed and improved with the soil body, and a time interval is provided, therefore, the foam for the shield has a certain stability, and the foam is not excessively decayed and destroyed before being mixed with the excavated soil body, so that the aim of improving the excavated soil is lost, but the current foaming agent has excellent foaming performance, but the stability of the foam is difficult to meet the requirement, and an additive is required to be added, so that the foaming stability is ensured.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and provides an easy-foaming shield foam additive.
The technical scheme for solving the technical problems is as follows: the easy-foaming shield foam additive comprises the following components in parts by weight: sodium lauryl sulfate: 15-20 parts of hexadecyl trimethyl ammonium chloride: 10-18 parts of fatty alcohol-polyoxyethylene ether sodium sulfate: 8-15 parts of amphiphilic polymer: 5-8 parts of polystyrene foam: 25-40 parts of modified cellulose: 4-12 parts of water: 80-90 parts of polyethylene glycol: 3-6 parts of foaming auxiliary agent: 3-5 parts of a foaming additive: 10-26 parts of a foam stabilizer: 3-7 parts of a dispersant: 5-8 parts of an acid catalyst: 3-8 parts, coagulant: 10-25 parts of hydrophilic auxiliary agent: 2-8 parts.
The invention further defines the technical scheme that:
the foaming aid is sodium bicarbonate.
The foaming additive is prepared by mixing diazene diformamide, fatty acid and calcium salt according to the mass ratio of 6-7:2-3: 1.
The foam stabilizer is one or two of nano hydroxyapatite or nano calcium carbonate.
The dispersant is one or a mixture of more of carbonate, lignosulfonate, hydroxymethyl ethyl cellulose or hydroxypropyl methyl cellulose.
The coagulant is at least one of sodium aluminate, lithium carbonate and anhydrous sodium sulfate.
The hydrophilic assistant is polyalkylene glycol.
The invention has the beneficial effects that: the foaming agent of the invention has high foaming rate, rich and fine foam, uniform distribution and small pores of generated bubbles, wherein, the lauryl sulfuric acid has excellent foaming performance, strong foaming capacity, rich foam and better wetting capacity, so that the generated foam can rapidly act on soil, the hexadecyl trimethyl ammonium chloride is a zwitterionic surfactant, the foam is fine and rich and can be compatible with various surfactants, the foam stabilizer has excellent effect on the stability of the foam, the structural stability of the foam can be improved by improving the viscosity of the foam or orderly distributing surfactant molecules in a bubble liquid film, the nano hydroxyl phosphorus lime has the characteristics of fine particles and self structure, so that a part of the surfactant in a foam system can be adsorbed on the surface of the particles, thereby leading the foaming volume to be slightly reduced, but the adsorption effect is weaker, so the foaming volume is basically kept constant along with the addition of the nano-hydroxyapatite; meanwhile, a hydration layer is formed around the hydroxyapatite, the hydration layer also exists around the bubbles, the hydroxyapatite is adhered to the outer wall of the bubbles under the action of the motion of a system solution and the surface attraction force to form a compact and mutually staggered protection layer, the hydroxyapatite is clamped between the bubbles to form a barrier for mutual combination of the bubbles, the breakage of the bubbles is slowed down, when the protection layers formed by the hydroxyapatite are mutually connected, the formed framework structure can support and protect the bubbles inside from being influenced by an external force, and the stability of the bubbles is improved; the polyethylene glycol has remarkable thickening and foam stabilizing properties, and can prolong the foam stabilizing time under the condition of stronger acidity
The dispersant is added to reduce the surface tension of the liquid solid particles, so that the surfaces of the solid particles are easy to wet and adsorb each other, the foaming performance of the foaming agent can be enhanced, the coagulant can quickly coagulate and harden the uniformly mixed and firmly adhered coagulation material, reduce foam breakage, and has high strength development speed and high mechanical strength; foaming auxiliary agent, foaming additive and acid catalyst, and can enhance foaming performance of foaming agent and increase foaming rate.
