Abstract
The present invention discloses sealant for an air conditioner, which comprises the following ingredients by weight percentage: 16 percent to 27 percent of adhesive type chloroprene rubber modified by antiageing agent, flame resisting agent and curing agent, 16 percent to 22 percent of 2402 phenol-aldehyde resin, 14 percent to 22 percent of CaCO<3> or talcum powder filler and solvent prepared from toluene, acetic ether and gasoline. Fluid sealant is obtained after reaction in a reaction still for 24 hours under normal temperature and pressure. The present invention has the advantages of rapid curing speed, fire resistance, good chemical stability in high and low temperature, capability of effective noise reduction for an air conditioner and capability of energy consumption reduction.
Description
The invention relates to research, refer more particularly to the seal gum that is used for seam between the air conditioning machinery inwall wallboard a kind of sealant composition.
Air conditioning machinery and environment carry out heat exchange to be realized by axial-flow fan.The axial-flow fan housing is that spot welding connects at present, and the slit is big, thereby has caused the air quantity leakage.So both make power loss, also caused noise.People's imagination is filled out the slit with sealing material for this reason.The way of most convenient is to utilize glue or liquid sealing material to be coated on the slit, solidifies in very short time.As polyurethane glues (CN1091765A), but this material cost height, economic benefit is not good, a kind of application rubber-type liquid sealing material (CN1048050A) that is coated with is arranged again, but it is not fire-retardant, condition of cure requires high, and the chemical stability when high temperature is bad, thereby is unsuitable for using on the air-conditioning.Application number is that 94101867.9 patent application then discloses a kind of rubber-type sealing material, its sealing property is better, stable chemical performance, but it exists with solid form, can not resemble glue or liquid sealant-coating and locate, on the air-conditioning production line, use difficulty in the slit.
The object of the present invention is to provide that a kind of fire-retardant, high low temperature chemical stability is good, the seal gum of quick solidifying, it can seal slit between the air conditioning machinery wallboard easily, is suitable for fitting work on the streamline.
The objective of the invention is by comprising the adhesive type chloroprene rubber, zinc oxide, magnesium oxide, antimonous oxide, clorafin, N-phenyl-2-naphthylamines, toluene, ethyl acetate, 2402 resol, gasoline, the composition that lime carbonate or talcum powder are formed is realized, at first utilize zinc oxide, magnesium oxide, antimonous oxide, clorafin, N-phenyl-2-naphthylamines is to the modification of adhesive type chloroprene rubber, again with chloroprene rubber after the modification and toluene, ethyl acetate, 2402 resol, gasoline, lime carbonate or talcum powder synthesize the seal gum that is used on the air conditioning machinery, and modification adhesive type chloroprene rubber prescription is:
The gluing formulation chloroprene rubber 25 of weight of material (kilogram)
ZnO 1.25-1.5
MgO 1-1.5 N-phenyl-2-naphthylamines 0.2-0.4 tri-chlorination two antimony 2.5-2.8
Clorafin 0.5-0.8 with the prescription that modified chloroprene rubber and other material synthesize seal gum is:
Weight of material (per-cent) modified chloroprene rubber 16-27%
Toluene 10-19%
Ethyl acetate 10-19% 2402 resol 16-22%
Gasoline 7-18% CaCO
3Or talcum powder 14-22%
In modification adhesive type chloroprene rubber prescription, zinc oxide and magnesium oxide are as solidifying agent, antimonous oxide and clorafin are as fire retardant, each mixing of materials of chloroprene rubber modification opened be smelt film, the graphite that also can add 1-1.5kg in addition in modification adhesive type chloroprene rubber prescription is as weighting agent and make toner.The fineness of ZnO and MgO is between the 200-400 order.
To put in the reactor by the modified chloroprene rubber sheet that above prescription makes, make reactor under normal pressure, the solvent that temperature is controlled under 20-40 ℃ and toluene, ethyl acetate, gasoline are formed, play that plasticising is toughness reinforcing, 2402 resol of solidifying agent effect, as the CaCO of weighting agent
3Or raw material such as talcum powder synthesizes, and the compound that has reacted gained is gelationus seal gum, and available pressure is irritated the shape machine and got in the plastic hose of toothpaste-like.During use, only need seal gum in the flexible pipe is extruded on the envelope crack that is coated between the air-conditioning wallboard.Sealing glue at normal temperatures, do not need external pressure with regard to Pasting on wallboard, and mobile little, just curable in the extremely short time.
The present invention is with the prior art ratio, it designs at the requirement of air conditioning machinery wallboard gap sealing, so have very strong specificity: one, it is by carrying out modification to gluing formulation chloroprene rubber interpolation antimonous oxide and clorafin, have fire retardation, meet safety requirements on the air-conditioning.Its two: select for use gluing formulation chloroprene rubber as main raw material, it mobile little, cohesive force is strong, does not need external pressure to bond, thereby uses easily.Its three: chloroprene rubber and 2402 resol blend, the gained elastic properties of materials is good, thereby sealing effectiveness is good.Its four: raw material, additive, solvent and their proportioning institute constitution system that sealing glue is selected, at room temperature can very fast curing, meet the suitability for industrialized production requirement on the streamline.Its five, by the modification to chloroprene rubber, gained seal gum chemical stability is good, uses under the hot conditions all reliable at low temperature.Its six, sealing glue is flow-like, is coated on the slit just, thereby uses easily.In addition,, can reduce air-conditioning noise effectively, reduce energy waste owing to use sealing glue can stop air quantity to leak, and the present invention raw materials used all are general chemistry raw materials, cheap.
By the following examples the present invention is further described.
Embodiment 1, material formula all by weight, the unit kilogram.
Gluing formulation LDJ-240 chloroprene rubber 25kg, 300 purpose ZnO 1.3kg, 300 purpose MgO 1.3kg, 0.2kg N-phenyl-2-naphthylamines, 1kg carbon black, 2.5kg antimonous oxide, 0.6kg clorafin at room temperature, opens refining 45 minutes in two roller rubber mixing machines, makes the modified chloroprene rubber film.
