Abstract
A high-wt. wall element consists of the following materials in wt. ratio (portions): magnesium oxide 80-120, magnesium chloride 35-45, talcum powder 3-6, water-proofing powder 3-6, urea formaldehyde resin 0.4-0.8, filler 40-80 and additive 0.5; and the filler being saw dust, crushed rice straw or crop stems. Its making method is as follows: the magnesium oxide, filler, etc. are weighed according to wt. proportion and are uniformly mixed; the magnesium chloride is further dissolved by adding water, and the dissolved urea formaldehyde resin and addtiive are further added; then magnesium chloride mixed solution is poured into the dry material and stirred to make a slurry, and the slurry is injected into a mould, tamped to formation, demoulded after hardening, then is trimmed and inspected to obtain the product. Advantages are stable crystalline structure, no strength decrease during soaking in water, and long-term stability.
Description
Technical field
The present invention relates to a kind of light wall material, also relate to the manufacture method of this materials for wall.
Background technology
Infilled wall in the construction work or in the building frame uses clay brick or concrete grey sanded brick for many years, and silica-magnesia panel is promoted in examination now.Fire clay brick and destroy arable land, consumes energy, and body of wall is heavy, the framework load is big, building cost is high, so clay solid brick is forbidden in 160 cities, the Ministry of Construction explicit order whole nation in limited time.In recent years, came the substitute for clay brick with holllow building block gradually, the holllow building block that wherein useful slag, flyash are made as stopping composition, also useful light sandwich Taibai panel is made infilled wall.Though wall weight reduces, but still has some problems, slag holllow building block intensity is relatively poor, and lightweight Taibai panel production investment is huge, unfavorable promoting the use of.Disclosed 94,110,824 1 kinds of light-weight hollow building block mades in the Chinese patent literature are that aggregate accounts for total raw material 41-48% with the mixture of ground silica or magnesium oxide, magnesium chloride, and with wood sawdust, to pulverize straw etc. be stopping composition, accounts for 50-55%, other adds jelling agent 2-4%.The magnesium oxide consumption accounts for the 23-27% of building block batching total amount, and the magnesium chloride consumption accounts for the 2-4% of total amount.This material, though in light weight, draw materials easily, easy to make, there is a deadly defect, anti-halogen phenomenon is serious under moist situation, and along with the prolongation of time, its intensity progressively reduces simultaneously.The like product that examination is in China at present promoted all has this phenomenon.
Summary of the invention
To be the anti-halogen phenomenon that exists of materials for wall that main raw material is made and to prolong the problem that reduces intensity in time in order to solve with magnesium oxide, magnesium chloride, stopping composition etc., through the repetition test research of more than ten years, develop a kind of more satisfactory light wall material and manufacture method finally.
Light wall material of the present invention is characterized in that, is made up of the raw material of following weight part:
Magnesium oxide 80-120 part, magnesium chloride 35-45 part,
Talcum powder 3-6 part, water-proofing powder 3-6 part,
Urea-formaldehyde resin 0.4-0.8 part, stopping composition 40-80 part,
0.5 part of additive, additive is made up of the following raw materials according weight part:
Sodium pyrosulfate, ferrous sulfate, sodium hydroxide, each 0.08-0.15 part of Sodium Silicofluoride, potassium permanganate 0.06-0.12 part.
Stopping composition is wood sawdust, pulverizing straw or straw and agricultural crop straw etc.
The making method of light wall material of the present invention is:
It is even to take by weighing magnesium oxide, talcum powder, water-proofing powder, stopping composition mixing dry mixing by weight; Again magnesium chloride is dissolved in water, adds the urea-formaldehyde resin mixing again, take by weighing additive raw material more by weight and pour in the magnesium chloride mixture solution with water dissolution; Then the magnesium chloride mixed solution is poured into and stirred into wet slurry in the siccative; Wet slurry is injected mould, and building block adds glass cloth or silk, the compaction moulding that vibrates when big, sclerosis back form removal, finishing, check finished product.
Product of the present invention has the following advantages: 1. because chemical reaction is arranged, product produces stable crystal phase structure in process of setting, thereby makes product not anti-halogen in wet environment, does not also reduce intensity during water logging; 2. the destruction of having contained crystal phase structure in the product with leach, product can be in steady state for a long time; 3. can produce solid slab, cored slab, little medium-sized building block and the building and ornament materials of various models by national standard.With other material of construction good adhesive effect is arranged; 4. product weight is light, intensity is high, anticorrosive, ageing-resistant, do not burn; 5. can suitably reduce construction costs, improve operating efficiency; 6. raw material 30% is to adopt worker, agriculture production waste, can turn waste into wealth.
Embodiment
