Abstract

The invention provides sealing for a biogas generating pit and a preparation method for sealing coating, wherein, the sealing coating is prepared by formulating curing agent in proper proportion by using unsaturated polyester resin as primary sealing raw material, glass fiber is adhered to the wall of the pit after a layer of sealing coating is coated thereon, a layer of sealing coating is subsequently coated on the glass fiber to be naturally cured and formed to thereby complete the sealing operation, which effectively resolves the defect of inferior sealing quality of the wall of the cement-poured biogas generating pit, the cured unsaturated polyester resin has good acidic resistance, alkali resistance, sealing performance and long service life, and the method is simple in process, low in cost and strong in operability, and according to the actual test, 80 kilopascal water column pressure drops to 'zero' after 24 hours.

Description

The preparation method of a kind of methane-generating pit sealing and gasket coating
Technical field
The present invention relates to a kind of sealing method, the preparation method of a kind of specifically methane-generating pit sealing and gasket coating.
Background technology
Methane-generating pit is the emerging energy that is used for vast rural area more and more widely that the current whole nation is being widelyd popularize, and it is done rural environmental hygiene well and play an important role solving peasant's fuel.But mostly there is the phenomenon of leaking, leaking gas in the methane-generating pit that cement is built, and causes existing methane-generating pit benefit low, and level of application is not high, and biomass pool built from glass fiber reinforced plastic good seal but have the shortcoming of rigidity difference.
Summary of the invention
The invention provides the preparation method of a kind of methane-generating pit sealing and gasket coating, solved cement effectively and built the poor shortcoming of methane-generating pit pool wall sealing.
The technical solution used in the present invention is: be main sealing raw material by dion unsaturated resin, solidifying agent through the preparation suitable proportion is made gasket coating, is sticking glass fibre behind brushing one deck gasket coating on the pool wall, and then is brushing one deck gasket coating, seal operation is finished in the spontaneous curing moulding.
Because effective curing of solidifying agent is subjected to extraneous thermal effect bigger, the configuration proportion of dion unsaturated resin and solidifying agent changes with the variation of outside temperature, and concrete configuration proportion is:
During 20 degrees centigrade of outside temperatures: the solidifying agent of the dion unsaturated resin preparation 4ml of 250ml under other temperature, is a benchmark with the dion unsaturated resin of 250ml, the every rising of temperature or descend 5 degrees centigrade, solidifying agent increase and decrease 1ml.
The invention has the beneficial effects as follows: dion unsaturated resin solidifies that the back is acidproof, alkaline-resisting, good seal performance, long characteristics of life-span, and this method technology is simple, cost is low, workable, through 24 hours 80 kPas of water colunm pressures of reality test, pressure is reduced to " zero ".
Embodiment
Be described further below in conjunction with embodiment:
Embodiment:
During 20 degrees centigrade of temperature; according to the ratio of 250ml dion unsaturated resin than 4ml solidifying agent; make gasket coating through stirring; built after the methane-generating pit demoulding at methane-generating pit pool wall external coating one deck gasket coating; paste layer of glass, brushing one deck gasket coating again, gasket coating is advisable to soak into glass fibre; need not make protective layer in addition, the spontaneous curing moulding.

Claims (2)

1, the preparation method of a kind of methane-generating pit sealing and gasket coating, it is characterized in that, by dion unsaturated resin is main sealing raw material, solidifying agent through the preparation suitable proportion is made gasket coating, sticking glass fibre behind brushing one deck gasket coating on the pool wall, and then brushing one deck gasket coating, seal operation is finished in the spontaneous curing moulding.
2, preparation method according to claim 1, it is characterized in that, the configuration proportion of dion unsaturated resin and solidifying agent changes with the variation of outside temperature, concrete configuration proportion is: during 20 degrees centigrade of outside temperatures: the solidifying agent of the dion unsaturated resin preparation 4ml of 250ml, under other temperature, dion unsaturated resin with 250ml is a benchmark, the every rising of temperature or descend 5 degrees centigrade, solidifying agent increase and decrease 1ml.
