Inorganic mineral waterproof active master batch

Abstract

The invention discloses an inorganic mineral waterproof active master batch, which comprises the following raw materials in percentage by weight: 20 to 80 percent of attapulgite or modified attapulgite, 5 to 20 percent of a thickening moisturizer, 5 to 30 percent of water glass, 10 to 30 percent of active aluminum salt, 0 to 15 percent of an early reinforcing agent and 0 to 5 percent of a water reducing agent. The waterproof active master batch is a permeable crystalline dense waterproof material, is obtained by dry mixing of various active mineral auxiliaries, and is an advanced novel powdery waterproof material which is green, odorless, nontoxic and pollution-free.

Description

technical field [0001] The invention belongs to the field of building decoration materials, and in particular relates to an inorganic mineral waterproof active masterbatch. Background technique [0002] After the hardening of traditional mortar concrete and other materials, due to factors such as water retention, shrinkage, internal air, and incomplete hydration, many tiny gaps and cracks will appear inside, making the facing water surface, back water surface, and slope of the building different. The running surface is eroded by rainwater, groundwater and internal water vapor, and there are phenomena such as hollowing, cracking, water channeling and water leakage. Therefore, water resistance has become one of the most important indicators for building detection. The existing waterproof technologies can be roughly divided into the following categories: [0003] 1. Foundation treatment: The current waterproofing generally adopts vibration compaction to ensure the impermeabili...

AI Technical Summary

Problems solved by technology

[0009] 1) Tamping method: Tamping and vibration have high requirements on equipment, and the internal air is not easy to discharge, so manual tamping results in high cost and low efficiency

[0010] 2) Film-coated coils are prone to cracking, and their internal polymers are prone to aging and cracking as time goes by during use, and the coils lack compressive capacity and are easily damaged and lost by physical shocks, resulting in damage to the waterproof effect

This type of construction method requires high conditions, complicated procedures, high labor costs, and inconvenient secondary construction, etc.

[0012] 4) Silicone oil, fluorosilicon and other materials can achieve a good hydrophobic effect, but they can only act on the surface, which is difficult to penetrate and fill holes and cracks

[0013] 5) The active masterbatch has been put on the market by means of imports. The current market price is about 40,000 to 60,000 yuan / ton, which greatly increases the production cost when applied to engineering, and the low cost performance makes it difficult for the market to accept
