Abstract
The invention discloses a concrete air-entraining and water-proof agent and belongs to the field of building materials. The concrete air-entraining and water-proof agent comprises the following components in parts by weight: 40-60 parts of rosin, 6-20 parts of sodium alginate, 5-12 parts of sodium hydroxide, 3-10 parts of sodium dodecyl benzene sulfonate, 15-40 parts of stearic acid and 0.5-3 parts of sulfuric acid. Tiny bubbles can be uniformly introduced to the concrete air-entraining and water-proof agent, the workability and the water-proofness are improved, the concrete durability is enhanced; and the concrete air-entraining and water-proof agent has excellent air-entraining performance and bubble stability performance and is suitable for concrete structures with anti-freezing and water proof demands.
Description
Technical field
The present invention relates to building materials field, specifically, relate to a kind of concrete bleed water-resisting agent.
Background technology
Construction industry more and more prosperous, drives the demand of material of construction is constantly promoted.For improving the concrete performance of building main raw, all kinds of concrete additives emerge in an endless stream.The concrete air-entrainer that wherein improves concrete durability, frost resistance just has a lot.But existing concrete air-entrainer exists the complexity of filling a prescription, draw bubble uneven, the not good deficiency that waits of waterproof.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of concrete bleed water-resisting agent is provided.
The technical solution adopted in the present invention is a kind of concrete bleed water-resisting agent, comprises rosin, sodium alginate, sodium hydroxide, dodecyl phenenyl sulfate, stearic acid, sulfuric acid; Each composition weight umber is rosin 40-60 part, sodium alginate 6-20 part, sodium hydroxide 5-12, dodecyl phenenyl sulfate 3-10, stearic acid 15-40 part, sulfuric acid 0.5-3 part.
Described stearic acid is one or more mixing wherein of sodium stearate, Magnesium Stearate, calcium stearate.
Preparation method of the present invention: rosin is put into reactor and be heated to 140 ℃ of thawings, then add above-mentioned sodium alginate, sodium hydroxide, dodecyl phenenyl sulfate, sulfuric acid, after slowly constantly stirring and get final product.
The present invention can evenly introduce micro-bubble, improves workability and water-repellancy, strengthens concrete weather resistance, has good bleed performance and bubble stabilizes performance, is applicable to having in the concrete structure of freeze proof, water-repellancy needs.
Embodiment
Embodiment:
A concrete bleed water-resisting agent, puts into reactor by 60 parts of rosin and is heated to 140 ℃ of thawings, then adds 15 parts of sodium alginates, 8 parts of sodium hydroxide, 5 parts of dodecyl phenenyl sulfates, 35 parts of stearic acid, 1 part of sulfuric acid, after slowly constantly stirring and get final product.
The present invention evenly introduces micro-bubble, improves workability and water-repellancy, strengthens concrete weather resistance, has good bleed performance and bubble stabilizes performance, is applicable to having in the concrete structure of freeze proof, water-repellancy needs.
