Abstract
The present invention relates to a chemical sand fixing and dust preventing agent and a preparing process thereof. The present invention is characterized in that butadiene, styrene, acrylic acid, persulphate and an anionic emulsifier are used for being stirred for 8 to 20 hours at the temperature of 50 to 90DEGC to be polymerized to generate carboxy styrene-butadiene latex. The dust preventing agent has the advantages and the effects of rapid sand fixation and dust prevention, good ventilation property in a mask in the shape of a sand face, no influence on plant growth, large penetration depth, no poison, no harm and favourable effects of water retention and soil retention. The present invention can be used for the urban dust prevention and the dust prevention of a building site, road repairing and earth work transportation.
Description
The present invention relates to a kind of chemical sand fixating agent, be applicable to that vegetative sand control, mechanical sand barrier fix the sand, the dustproof dedusting of construction site, road finishing, cubic metre of earth transportation.
The invention still further relates to the preparation method of this sand fixating agent.
The chemistry sand prevention was abroad just studied as far back as the thirties, the USSR (Union of Soviet Socialist Republics) and the U.S. are the countries of studying chemical sand-fixing the earliest, they utilize bitumen compound, sand fixating agents such as bitumen emulsion, oil, artificial-synthetic copolymer, but these sand fixating agents all exist different weak points, and bitumen compound will spray by stages, can not once finish troublesome poeration; Bitumen emulsion waters the water that carries out in advance of sand before use, and not only workload is big, and the water source difficulty, easily decomposes during transportation; Oil fixes the sand and forms polymkeric substance through peroxidation and photochmeical reaction, easily wind erosion, weathering, can only plant one season growing plants, the time of fixing the sand is short, and the cost height, also has a kind of latex rubber to fix the sand, its wear-resisting wiping is poor, cohesive force is low.
The objective of the invention is shortcoming and deficiency in order to overcome above-mentioned prior art, and provide a kind of sand-fixed dust-proof rapid, the hold-time is long, and is easy to operate, low-cost a kind of chemical sand fixating agent, thus sand-fixed dust-proof technology popularization is used.
The present invention seeks to realize by following technical proposal:
A kind of chemical sand fixating agent is characterized in that it is the carboxylic styrene butadiene latex that is generated through polyreaction by the following weight proportion raw material:
Divinyl 30-60 part vinylbenzene 40-60 part vinylformic acid 1-3 part
Persulphate 0.15-0.45 part anionic emulsifier 0.05-0.1 part.
Wherein persulphate is Ammonium Persulfate 98.5 or Potassium Persulphate or Sodium Persulfate, and anionic emulsifier is sodium lauryl sulphate or Sodium dodecylbenzene sulfonate or the alkylphenol oxyethane basic thing that contracts; Sand fixating agent adds the octadecylamine polyoxyethylene and carries out modification, and its add-on is the 1-3% of sand fixating agent weight; Be used for sand-fixed dust-proof, add additive, add-on is the 0.5-1.0% of sand fixating agent weight; Additive is triethanolamine oleate or stearic acid or Vaseline or machine oil.
The preparation method of sand fixating agent is characterized in that it is undertaken by following step:
With 30-60 part divinyl, 40-60 part vinylbenzene, 1-3 part vinylformic acid, 0.15-0.45 packing into, part persulphate, 0.05-0.1 part anionic emulsifier in the reactor, carry out heated and stirred, Heating temperature is 50-90 ℃, stirs and carries out polyreaction in 8-20 hour, generates the carboxy styrene-butadiene rubber milk product.
Sand fixating agent of the present invention is a kind of polymkeric substance, by divinyl, vinylbenzene and vinylformic acid persulphate bring out with the anionic emulsifier effect under, generate carboxylic styrene butadiene latex, its performance is as follows:
Viscosity＜100 centipoises, PH=9.5-10.5
Surface tension＜4.8 dyne/cm
2, particle diameter 3000-2400A
The mechanically stable life is less than 0.3%, and transformation efficiency is more than 98%.
When being used for sand-fixed dust-proof, this sand fixating agent is added compound, as triethanolamine oleate, stearic acid, Vaseline and machine oil, can prevent to solidify, be convenient to fix the sand spray.
This sand fixating agent adds the octadecylamine polyoxyethylene and carries out modification, makes its perviousness better.
Owing to take technique scheme, make this technology compared with the prior art have following advantage and effect:
A) sand-fixed dust-proof can be finished in 5-10 hour rapidly, formed the fine and closely woven nethike embrane of one deck at Shamian Island, can keep 1-3;
B) do not change the porousness of sand bed, soil, after the sand bed soil fixing, water-permeable and water-absorbent are all very high, after planting, do not influence plant-growth, break through the soil, and water conservation is protected soil;
C) depth of penetration 1-5mm in the situation of 12 grades of strong wind, can not sweep nethike embrane;
D) nontoxic pollution-free, viscosity is big, is not afraid of wind erosion, weathering, and wear resistance is good;
C) easy to operate, cost is low, and raw material sources are wide, and the preparation method is simple.
