Abstract
The present invention provides a polybenzene foamed concrete heat-insulating material made of waste polystyrene foamed material and combining it with cement and foaming agent and its preparation method. Its composition includes (wt%) 4%-10% of polystyrene granules with 15 mm-30 mm grain size, 81%-91% of cement, 0.4%-1% of foating agent and 4%-8% of water. It has the advantages of saving energy, protecting environment, low thermal coductivity and low cost.
Description
Technical field
The present invention relates to a kind of material of construction, specifically a kind of cement, polystyrene foam add the lagging material that foaming agent is made, and the invention still further relates to the preparation method of this lagging material.
Background technology
The specification of polybenzene foamed concrete thermal-insulating material and shape have two kinds: a kind of is to cast according to present situation to be shaped, can be irregular; Another kind is can water to make: 60mm * 500mm * 1000mm, 600mm * 300mm * shapes such as 80mm.With regard to lagging material, at present China market mainly contains perlite block, sheet material, polypropylene foam plate etc. are moulded in agent, but all there is the problem of some technical elements in these miscellaneous products, and the material thermal conductivity that has is up to standard, and resistance to pressure is bad; The bending resistance that has, crushing resistance are good, and thermal conductivity is not up to standard; There are aspects such as cost and power consumption, expensive source all to exist certain problem again, though for example the perlite product cost is lower, this product suction, a drum, expansion, and also power consumption is high, so the use back is endangered bigger.The extruded sheet thermal conductivity is less, and weak point is all being arranged aspect resistance to compression, bending resistance, the anti-intensity and on the cost.The polypropylene foam plate also is to have power consumption, shortcoming that cost is high equally.So, only meet the product innovation of Economic development requirement, could replace the currently available products of existing market.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art and provide a kind of waste product polyethylene that utilizes in conjunction with cement and foaming agent and the polybenzene foamed concrete thermal-insulating material of making.It has energy-saving and environmental protection, thermal conductivity is low, cost is low advantage.
Another object of the present invention is to provide a kind of preparation method of polybenzene foamed concrete thermal-insulating material.
Purpose of the present invention can reach by following measure.
A kind of polybenzene foamed concrete thermal-insulating material, its component and content are: 15 millimeters-30 millimeters granules of polystyrene: 4%～10%, cement: 81%～91%, foaming agent: 0.4%～1%, water: 4%-8%, all percentage ratios are weight percentage.It is to utilize foaming agent to make cement play the hole, and combining well with granules of polystyrene under the situation that does not influence cement character forms.
The production method that above-mentioned each component is made lagging material of the present invention is:
1. foaming agent is added water with 15 millimeters-30 millimeters granules of polystyrene and cement and mix stirring, lay the smooth bulk of making;
2. add cement with foaming agent again and add water and stir into slurries, slurries are covered the block surface, make slurries naturally osmotic after coagulation and form the lagging material of an integral body.
The foaming agent that the present invention adopts has various ways, as: gum rosin foaming agent, the agent of resin saponin fat vacuole foam, the plumbous foaming agent of oil yellow acid, hydrolysis blood foaming agent, polyurethane foam agent etc.
Polybenzene foamed concrete can reach the building operation needs by the scope of adjusting the component amount, and it has very strong modulability, can satisfy different construction requirements, as roofing, balcony, metope and filling part.
The present invention compared with prior art has following advantage.
The present invention have that thermal conductivity is low, intensity good, from heavy and light, good toughness, do not absorb water, do not expand, difficult to burn, nontoxic, tasteless, modulability is good, the cohesive force advantages of higher.
2. environmental protection: main raw material of the present invention is: waste polystyrene foam, it is that waste product utilizes renewable resource, can reduce white pollution again, is good environmentfriendly products.
3, energy-conservation: making of the present invention only need utilize a spot of energy, has only 40～60% of other product institute energy requirements.
4, low, the easy construction of cost, product stability are good.
Characteristics of the present invention are that polystyrene foam and the cement that thermal conductivity is low well combines by foaming agent, make promptly heat insulation, the sound insulation again of this lagging material have certain resistance to compression, bending strength simultaneously.
