Abstract
The invention discloses a waterproof daub, comprising the following raw materials in parts by weight: 80-100 parts of coal tar, 10-15 parts of epoxy resin, 0.5-1.0 parts of calcium carbonate, and 20-40 parts of alumina powder. The epoxy resin is bisphenol A type epoxy resin. The preferred composition of the waterproof daub is: 85-90 parts of coal tar, 12-15 parts of epoxy resin, 0.6-0.8 parts of calcium carbonate, and 30-35 parts of alumina powder. The technical effect of the invention is that the waterproof daub has the advantages of wide raw material resource, low cost, easy production, ageing-delaying property, long service life, acid and alkali erosion resistance, good waterproof effect, no flowing under high temperature and no crack under low temperature.
Description
Technical field
The present invention relates to a kind of material of construction, specifically is a kind of waterproof clay.
Background technology
The present building trade bituminous water-proof coating that is widely used, or in the concrete grey of building a wall, dose CaCl2-powder and cement mortar and ooze and lump together, very strong water-proof function had; Complex process, construction is lost time, for using pitch prill that serious pollution is arranged; Plastic ointment is that raw material is made waterproof paint, must synthesize by high temperature, and secondary plasticizing; Material aging is rapid, does not reach requirement during low temperature.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of good water-proof effect, the waterproof clay of acid and alkali-resistance.
Technical scheme of the present invention is achieved in that a kind of waterproof clay, comprises the raw material of following mass fraction: coal tar 80-100 part, epoxy resin 10-15 part, lime carbonate 2-5 part, aluminum oxide powder 20-40 part.
Described epoxy resin is bisphenol A type epoxy resin.
The preferred group of waterproof clay becomes: coal tar 85-90 part, epoxy resin 12-15 part, lime carbonate 3-4 part, aluminum oxide powder 30-35 part.
The preparation method of this waterproof clay is: prepare to drop in the reaction kettle behind the raw material and stir, heat 100-150 ℃ then, be incubated and promptly get waterproof clay after 1-2 hour, this product can directly be used for the building surface coating.
Technique effect of the present invention is: the raw material sources of waterproof clay of the present invention are extensive, cost is low, production is easy, and delaying retrogradation, life-span are long, are not afraid of the soda acid etch, good water-proof effect, and high temperature does not trickle, not embrittlement of low temperature.
Embodiment
