Problems solved by technology

[0002] The demoulding technology in the existing air-entrained concrete production process mainly uses waste engine oil and heavy oil to demould, resulting in oil stains on the surface of the block. Such oil-stained blocks on the surface will cause cracking, hollowing, and peeling off of the aerated concrete wall. Serious engineering problems such as affecting the pass rate of products, polluting the production workshop and molds, reducing the air quality in the workshop, and harmful to the health of the workers

Embodiment 1

[0017] Under high-speed stirring at 70-100°C, add 0.5 kg of higher fatty acid sodium, 1.5 kg of paraffin, 0.5 kg of polysorbate 80, and 15 kg of waste engine oil to 82.5 kg of water; and add an appropriate amount of preservatives and stabilizers at high speed After stirring for 3 minutes, it becomes a light yellow emulsion.

Embodiment 2

[0019] Under high-speed stirring at 70~100°C, add 1 kg of higher fatty acid sodium, 3 kg of paraffin, 0.8 kg of polysorbate 80, and 25 kg of waste engine oil to 70.2 kg of water; and add an appropriate amount of preservatives and stabilizers at high speed After stirring for 3 minutes, it becomes a light yellow emulsion.

Embodiment 3

[0021] Under high-speed stirring at 70-100°C, add 0.7 kg of higher fatty acid sodium, 2 kg of paraffin, 0.7 kg of polysorbate 80, and 20 kg of waste engine oil to 76.3 kg of water; and add an appropriate amount of preservatives and stabilizers at high speed After stirring for 3 minutes, it becomes a light yellow emulsion.

[0022] The present invention has the following characteristics:

[0023] 1. High efficiency: firstly, the present invention has the characteristics of erosion resistance and autoclave resistance, and both the scoured surface and the autoclaved curing surface of the mold can be completely demoulded during the pouring process; secondly, it solves the problem of aerated concrete walls caused by oily blocks Serious engineering problems such as body cracking, hollowing, and peeling of the finish layer have been eliminated, and the product qualification rate has been improved.

[0024] 2. Environmental protection and energy saving: the main component of the inve...

Abstract

The invention provides an energy-saving environment-friendly mold releasing agent for production of aerated concrete. The mold releasing agent comprises, by mass, 0.5 to 1.0% of higher fatty acid sodium, 1.5 to 3.0% of paraffin, 0.5 to 0.8% of polysorbate 80 and 15 to 25% of waste engine oil, with the balance being water. The mold releasing agent further comprises an antiseptic and a stabilizing agent. The mold releasing agent provided by the invention can overcome the problem of a greasy surface of a building block, improves the qualified rate of products, is environment-friendly and energy saving, produces no pollution and reduces consumption of a petroleum product.

Description

【Technical field】 [0001] The invention relates to the field of building materials, in particular to an energy-saving and environment-friendly release agent for the production of air-entrained concrete. 【Background technique】 [0002] The demoulding technology in the existing air-entrained concrete production process mainly uses waste engine oil and heavy oil to demould, resulting in oil stains on the surface of the block. Such oil-stained blocks on the surface will cause cracking, hollowing, and peeling off of the aerated concrete wall. And other serious engineering problems affect the qualified rate of products, pollute the production workshop and molds, reduce the air quality of the workshop, and are harmful to the health of the workers. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide an energy-saving and environment-friendly release agent for the production of air-entrained concrete, which can solve the oil surfa...
