specific Embodiment approach 1

[0017] Its specific implementation mode one is:

[0018] 1. Remove impurities from raw materials by filtering;

[0019] 2. Mix the water and silane in the raw materials according to their weight ratio of 2:1 and then stir, put the stirred solution into the reactor and heat to 70°C, and then heat for 60 minutes;

[0020] 3. Add sodium abietate into the reactor according to 2% of the weight of the silane, and heat and stir for 30 minutes at a temperature of 70°C;

[0021] 4. Add sodium hydroxide into the reactor according to 50% of the weight of the silane, and heat and stir for 30 minutes at a temperature of 70°C;

[0022] 5. Lower the temperature to 50°C and stir for 30 minutes, adjust the pH value to 10, and cool naturally to form the waterproofing agent.

Abstract

The present invention discloses a production process for a novel permeable crystallization water proofing agent. According to the production process, silane, sodium abietate, sodium hydroxide and water are adopted as main raw materials; the raw materials are diluted according to a certain dilution ratio and sequentially added; treatments of heating, uniformly stirring and cooling are performed to form colorless and transparent liquid, which is the novel permeable crystallization water proofing agent, wherein the dilution radio of the silane to the sodium abietate to the sodium hydroxide to the water is 100:50:1:25. The novel permeable crystallization water proofing agent provided by the present invention has the following advantages that: the prepared water proofing agent through the production process provided by the present invention provides excellent waterproof performance and impermeability performance for mortar and concrete, such that the water proofing service life is substantially prolonged, the aging resistance properties of the mortar and the concrete are enhanced, the service life of the whole reinforced concrete building is prolonged; the novel permeable crystallization water proofing agent is nontoxic, and does not cause the pollution to the environment during the production process and the use process.

Description

technical field [0001] The invention relates to a production process of a osmotic crystalline waterproofing agent. Background technique [0002] At present, linoleum, paste and various waterproof coatings are widely used in domestic building waterproofing projects, which have short service life, easy aging, high cost, limited range of use, complicated construction, toxicity, and serious environmental pollution. It is difficult to construct in complex parts, high technical requirements, time-consuming and labor-intensive and other shortcomings. Contents of the invention [0003] The purpose of the present invention is to provide a production process of a new type of osmotic crystalline waterproofing agent, which overcomes the above-mentioned problems existing in the existing waterproofing technology, and the waterproofing agent produced by this process can form excellent waterproofing and impermeability to mortar and concrete, greatly improving Extend the service life of w...
