Abstract

The invention relates to a method for preparing a sound insulation coating. The sound insulation coating prepared by the method is prepared from, by weight parts, 10-20 parts of acrylic emulsion, 2-7 parts of bamboo charcoal, 2-5 parts of flame retardant, 10-20 parts of mixed solvent, 1-1.5 parts of wetting agent, 1-1.5 parts of ceramic powder, 1-2 parts of dispersing agent, 1-2 parts of adhesive, 5-10 parts of inorganic thickener, 5-8 parts of flexibilizer, 2-4 parts of mica powder, 10-15 parts of detergent, 2-5 parts of swelling agent and 20-30 parts of water. The sound insulation coating has effects of purifying air and adjusting humidity. The coating contains plenty of pores, so that the internal surface area is large, poisonous and harmful gas in the air can be adsorbed, and the sound insulation coating can have the effect of regulating indoor air humidity.

Description

A kind of preparation method of deadener

Technical field

The present invention relates to a kind of preparation method of deadener.

Background technology

The sound-proof material of existing traditional architectural decoration is all based on glass fibre, its shortcoming is that glass fiber material is to low-frequency sound-absorbing weak effect, does not have fire retardation, can not mosquito proof, and not only material itself is harmful, also obnoxious flavour can be produced when burning.

The sound pollution that modern society occurs, especially room noise pollute to the harm of healthy and daily life gradually by people are paid attention to, and therefore, a lot of modern architecture needs when design the soundproof effect considering its inside.Sound-proof material not only can improve indoor tonequality environment, and also plays very important effect to noise control.The kind of traditional building sound-proof material is a lot, and common mainly contains gypsum decorative acoustic board, glass wool decoration acoustic absorption, rock (ore deposit) cotton decoration acoustic absorption, pearlite decorative acoustic board, polystyrene foamed plastics decoration acoustic absorption, metal finishing acoustic board, perforated microstructure acoustic board etc.These acoustic boards, owing to being subject to limitation of size, not easily being stored, are transported, assembled, and some material surface also needs supplementary protection and ornament layer.And rock (ore deposit) cotton material is harmful, if improper use has carcinogenic danger; Polystyrene foamed plastics acoustic board ventilation property and thermotolerance bad, meet fire can discharge harmful gas; And porous metal plate sound-absorbing material and perforated microstructure acoustic board, cost is too high, is not also widely used.

But it is not high to there is following several problem: NRC in current announced patented technology, and soundproof effect is limited; The flame retardant properties of product is not good enough; The irritant obnoxious flavour releasing of gluing emulsion etc. in drying process.Patent CN1425720A (application number 03118445.6) discloses a kind of sound-absorbing environment protection paint, this coating adopts flyash pearl of wafing to make light skeletal, to improve soundproof effect, but due to flyash waft pearl pore close, not penetrating, make this coating soundproof effect undesirable.Patent CN1429869A (application number 01145015.0) discloses a kind of special flashing and sound-absorbent coating for music hall, and this coating with the addition of light pearl stone and foam polystyrene particle, produces certain sound-absorbing soundproof effect; But foam polystyrene particle meets fire can discharge poison gas, so this coating exists potential safety hazard.

Summary of the invention

The object of the invention is to: just to prior art defect, provide that a kind of soundproof effect is good, safety and environmental protection, deadener and preparation method thereof.

The technical solution used in the present invention is such:

A preparation method for deadener, its concrete steps are as follows:

(1) by ACRYLIC EMULSION 10-20 part, bamboo charcoal 2-7 part, fire retardant 2-5 part, mixed solvent 10-20 part puts into the reactor heated and stirred 5-10 minute with agitator, and temperature, at 60-65 DEG C, then sends into storage tank;

(2) by wetting agent 1-1.5 part, ceramics powder 1-1.5 part, dispersion agent 1-2 part, tackiness agent 1-2 part is put into reactor and is stirred 8-10 minute, and temperature, at 60-65 DEG C, then puts into another storage tank stand-by;

(3) mixture handled well in step (1) and step (2) has been delivered to inorganic thickening agent 5-10 part with two volume pumps respectively simultaneously, in the mixing tank of toughner 5-8 part and water 20-30 part, by all the other components: mica powder 2-4 part, purificant 10-15 part, swelling agent 2-5 part is sent in mixing tank with another volume pump successively simultaneously, be uniformly mixed 15-20 minute through 2500-3000r/min, temperature controls at 100-110 DEG C, becomes material after final cooling.

Further, propyl carbinol 2-8 part is also added in described step (2), dimethylbenzene 3-8 part, pigment 1-2 part, smoke suppressor 3-7 part.

In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: damping of the present invention is good, and sound-proofing properties is high, the material to human body and bad environmental can not be produced; Deadener of the present invention purifies air in addition, regulates the effect of humidity, a large amount of hole contained in film, and internal surface area is large, can toxic and harmful in absorbed air, can regulate the effects such as indoor air humidity simultaneously.
