Description

A kind of composite baking-free knot pervious floor tile adding modification pomelo peel bagasse

Technical field

The present invention relates to building material technical field, particularly relate to a kind of composite baking-free knot pervious floor tile adding modification pomelo peel bagasse.

Background technology

Along with the aggravation of Development of Urbanization speed, urban surface progressively cover by the water preventing ability such as buildings and various concrete material, waterproof regional percentage is significantly increasing, and its fraction of coverage of some areas is more than 80%.Due to city drainability worse and worse, many cities one run into heavy rain, and its rainwater on road surface cannot seepage fast, is easy to cause urban waterlogging.Therefore, for solving urban surface sclerosis problem, build high-quality natural living environment, safeguard balance of city ecosystem, the building material product-water-permeable brick of environmental protection arises at the historic moment, and is developed rapidly.

At present, common on market water-permeable brick mainly contains concrete permeable brick, ceramic water-permeable brick, sand base water-permeable brick etc.And the raw material that ceramic water-permeable brick is commonly used mainly contains phase red mud for many years, gold tailings, flyash, glazed ceramic, concrete etc.And the water-permeable brick prepared by these raw materials generally all needs the high temperature sintering through 1000-1400 DEG C, waste fossil oil, and produce industrial gaseous waste and cause topsoil.Sand base water-permeable brick is the novel water permeable brick grown up in recent years, with the drift-sand in desert for aggregate.Because sand base water-permeable brick emerges just trivial several years, extensive use is not also formed, and does not more further investigate the benefit that it produces.Store a large amount of drift-sand resources in desert, these drift-sands have the advantages that particle is tiny, water ratio is low, for development sand base water-permeable brick provides cheap starting material.From the angle of research, development and the performance analysis work of carrying out sand base water-permeable brick are conducive to improving China's water-permeable brick research system, and play and promote that sand base water-permeable brick is applied; From the angle of city ecology construction, be conducive to advancing Application of Urban Rain Water paces, alleviate the situation of city water resource scarcity; From the angle of desert treatment, be conducive to alleviating Desertification, and bring huge social economy and ecological benefits.As can be seen here, the research carrying out sand base water-permeable brick has major and immediate significance.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of composite baking-free knot pervious floor tile adding modification pomelo peel bagasse.

The present invention is achieved by the following technical solutions:

Add a composite baking-free knot pervious floor tile for modification pomelo peel bagasse, be made up of the raw material of following weight part: Desert Sand 50-53, novolac resin 4-5, urotropine 0.6-0.7, calcium stearate 0.2-0.22, water are appropriate, label is 42.5 silicate cement 42-45, flyash 5-6, Emulsion acrylic resin 3-4, pomelo peel 7-8, rice husk 4-5, hexalin are appropriate, tetrathio carboxylamine 12-14, haydite 150-160, zeolite 10-12.

Described a kind of composite baking-free knot pervious floor tile adding modification pomelo peel bagasse, be made up of following concrete steps:

(1) Desert Sand is washed post-drying and obtain baked sand, baked sand is put into fluidizing furnace, heating makes the temperature of baked sand rise to 160 DEG C, then baked sand is shifted in sand mill, keep constant temperature 160 DEG C, slowly novolac resin is added while mixed grind, mixed grind slowly adds the urotropine being dissolved in 10 times of water gagings in 80 seconds afterwards, continue mixed grind 60 seconds, when being blown into cold front heavy rain to 100 DEG C afterwards, add calcium stearate equably, mixed 30 seconds, shake out in crusher, air-cooled to fragmentation when 35 DEG C, cross 30 mesh sieves, obtain overlay film Desert Sand;

(2) baking oven is put into by after pomelo peel, the cleaning of rice husk water, dry with the temperature of 70 DEG C, pulverize after being cooled to room temperature, mix with the hexalin of total amount 5 times amount after crossing 20 mesh sieves, be stirred to after being uniformly dispersed and add tetrathio carboxylamine, stirring reaction 3 hours at 80 DEG C of temperature, then suction filtration, getting filter residue washes with water for several times, dries, obtain modification pomelo peel powdered rice hulls after cooling at 70 DEG C; To add in the water of 2 times amount in Emulsion acrylic resin, dispersed with stirring evenly after add above-mentioned modification pomelo peel powdered rice hulls, overlay film Desert Sand that step (1) obtains, send in mixer, stir 30 minutes with the speed of 600 revs/min, obtain skin-material;

(3) haydite is put into water soak 2 hours stand-by; Zeolite is put into crusher broken, then ball mill is put into, add appropriate water, wet-milling is taken out after 2 hours and is mixed with the haydite after immersion, put into stirrer, continue to add silicate cement and all the other remaining components that label is 42.5, the water adding total amount 10% after stirring 5 minutes with the speed of 800 revs/min continues stirring 10 minutes, obtains primer;

(4) primer is poured in mould, jolt ramming primer flattening surface, again skin-material is poured in mould, in the pressure system of 3MPa after 15 minutes after jolt ramming, freeze-day with constant temperature 48 hours at 25 DEG C, puts into standard concrete curing box maintenance 21 days and get final product on request by brick body after the demoulding.

Advantage of the present invention is: first the present invention carries out the process of coating thermoplastic resol to baked sand, obtain overlay film Desert Sand, the compositions such as tackiness agent are coordinated to make skin-material, give the permeable hole that water-permeable brick top layer is small, the macropore improving concrete brick body, easily by the shortcoming that mud blocks, also enhances aesthetic property; Coordinate the application of bottom concrete material, improve intensity and the water-permeable of brick body, and not only reduce production cost, also solve the environmental protection object of desert improvement.

The present invention with the addition of modified pomelo peel, rice husk in the preparation of skin-material, after mixing with overlay film Desert Sand, effect of fractionation by adsorption can be played, the heavy metal in rainwater and the surface water can be filtered, be convenient to the recycling of underground water, simultaneously with low cost, technique is simple, is convenient to realize suitability for industrialized production.
