Embodiment 1

[0023] First take 800kg of water, 20kg of polyvinyl alcohol, 80kg of acrylic acid-based copolymer emulsion, 1kg of sodium alkylbenzenesulfonate, 1kg of sodium nitrite, 0.4kg of tributyl phosphate, and 0.6kg of xanthan gum. Add 800kg of water and 20kg of polyvinyl alcohol into the reactor, heat to 95°C to completely dissolve the polyvinyl alcohol; lower the temperature to about 40°C, then add 80kg of acrylic-based copolymer emulsion and 1kg of anionic surfactant Sodium alkylbenzene sulfonate as an agent, fully stirred evenly; finally, 1kg of antirust agent sodium nitrite, 0.4kg of antifoaming agent tributyl phosphate and 0.6kg of thickening agent xanthan gum were added successively, fully stirred evenly, and filtered out That is the finished product.

Embodiment 2

[0025] First get 800kg of water, 16kg of polyvinyl alcohol, 90kg of acrylic acid-based copolymer emulsion, 1kg of sodium alkylbenzenesulfonate, 1.5kg of boric acid, 0.4kg of tributyl phosphate, and 0.6kg of xanthan gum. Add 800kg of water and 16kg of polyvinyl alcohol into the reactor, heat to 95°C to completely dissolve the polyvinyl alcohol; lower the temperature to about 40°C, then add 90kg of acrylic-based copolymer emulsion and 1kg of anionic surfactant Sodium alkylbenzene sulfonate, fully stirred evenly; finally add 1.5kg of antirust agent boric acid, 0.4kg of antifoaming agent tributyl phosphate and 0.6kg of thickener xanthan gum, fully stir evenly, filter and discharge to obtain finished product.

Abstract

The invention relates to a dust agglomerating agent which comprises, by weight, 2.5 to 10 parts of polyvinyl alcohol, 1 to 30 parts of acrylic acid-based copolymer emulsion, 60 to 96.5 parts of water, 0.01 to 1.0 part of anionic surfactant, 0.05 to 1.0 part of an antirust agent, 0.01 to 1.0 part of an antifoaming agent and 0.05 to 1.0 part of a thickening agent. The invention is advantaged in that the dust agglomerating agent with a simple mixing formula is brought forward and the dust agglomerating agent can effectively inhibit discharging of dust in road building, mining and related industries and reduce environmental pollution and harm to human bodies.

Description

technical field [0001] The invention relates to an auxiliary agent for protecting the environment, in particular to a binder for suppressing dust particles and a preparation method thereof. Background technique [0002] With the continuous development and progress of human society, people pay more and more attention to the earth environment on which they live. In all production industries, the requirements for environmental protection occupy a very important position. At present, during the transportation of goods, especially granular goods such as coal or sand, there are problems of particle splashing and dust during vehicle operation. Splashing particles and flying dust disperse in the environment causing safety, health and environmental concerns. Dust particles not only contaminate food and water, but when inhaled, can cause serious respiratory illness. [0003] Common methods of reducing dust are with fixed or mobile pressurized sprinkler systems, gravity feed distribu...
