Abstract
The present invention relates to a polystyrene foam plastic insulation brick which is composed of polystyrene foam plastics, fibrous material, glue, air-entraining agents, cement, early strength agents and water reducing agents. The preparation method is characterized in that the polystyrene foam plastics and the fibrous material are pulverized and cut; each component material is weighed according to a partition ratio and filled into a stirring device to be stirred into feed pulp by adding water; the feed pulp is injected into a brick die with multiple die cavities or a brick die with a large die cavity; then, the feed pulp is revitalized in the die, and the feed pulp is dried and solidified after the die is released. Using the waste polystyrene foam plastics as skeletal material, the polystyrene foam plastic insulation brick has the advantages of low cost, moisture resistance, freeze thawing resistance, good thermal insulation, advanced and reasonable manufacturing method, easy operation and high efficiency.
Description
The present invention relates to a kind of building thermal insulation material, specifically a kind of thermal insulation brick made of polystyrene foam plastics and manufacture method.
Insulating brick is pasted on the metope of building, because its coefficient of thermal conductivity is lower, can make building in severe cold winter or during the broiling summer, the temperature balance conduction of heat of inner temperature of room and external temperature is carried out slowly, thereby reach the effect of warm within doors temperature of maintenance or cold temperature.The insulating brick that uses is mainly made by perlite and cement at present, its production method is: perlite and cement are taken by weighing by 1: 10 proportioning, be put into mixing and water adding stirring in the agitator, then the blank that stirs is sent in the stock mould in monotype chamber according to quantity, extrusion modling on forcing press, and the demoulding at that time, be placed in and carry out natural Health preservation 10-15 days on the smooth place.This pearlite insulation brick and manufacture method thereof exist following weak point:
1, have trickle in the pearlite insulation brick body and hole that be communicated with has tangible capillarity, cause moisture content to infiltrate easily to retain, so pearlite insulation brick water absorption rate height, resistance to freezing and thawing is poor, and heat insulation effect can't satisfy all insulation requirements of modern architecture.
2, blank is an extrusion molding in the stock mould of monotype chamber on forcing press in the manufacturing process, is placed in the place after the demoulding and carries out natural Health preservation 10-15 days, and the production cycle is long, and efficient is low, and floor space is big.
The purpose of this invention is to provide a kind of is the insulating brick and the manufacture method thereof of the function admirable of aggregate with the polystyrene foam plastics.
The present invention is peculiar, the polystyrene foam plastics that will from rubbish and in the junk, reclaim, be aggregate through the processing development and use, the poly-third plastic warp packaging bag that to discard again, packing ropes etc. are through processing as fibrous material, and with cement and glue as cementitious material, be equipped with other auxiliary material and additive again, give full play of these materials characteristic separately, as polystyrene foam plastics coefficient of thermal conductivity 0.027-0.04, water only can moistening its surface, there is not the hair suction phenomenon ... Deng, make insulating brick obtain good protection against the tide, anti-thawing, insulation, caking property waits comprehensive physical property well.In its manufacture method, adopted many types of chamber stock mould or whole big injection molding of die cavity stock mould, build advanced effective production process such as buttress Shi Monei health, overcome present pearlite insulation brick and the existing weak point of manufacture method fully.
The object of the present invention is achieved like this: thermal insulation brick made of polystyrene foam plastics is made up of polystyrene foam plastics, fibrous material, glue, air entrained agent, cement, early strength admixture, water reducing agent, water, and it forms proportioning following (percentage by weight):
Polystyrene foam plastics 7-15%, fibrous material 0-6%, glue 10-20%, air entrained agent 0.5-2%, cement 51-80%, early strength admixture 0.5-1%, water reducing agent 0.5-2%, water 1.5-3%.
Polystyrene foam plastics mainly is to utilize the polystyrene foam plastics that reclaims from rubbish and junk, through processing as aggregate, the discarded poly-third plastic warp packaging bag, packing rope etc. through processing as fibrous material, also can be used materials such as finished product polystyrene foam plastics and glass fiber; Air entrained agent, early strength admixture, water reducing agent, glue are selected rosin soap, salt, wooden calcium, polyvinyl formal adhesive respectively for use.The polyvinyl formal adhesive is made up of polyvinyl alcohol, formaldehyde, water, hydrochloric acid, alkali.
The surface of finished product thermal insulation brick made of polystyrene foam plastics can be with plain ash, mortar is fine combine, be the recessed coarse convex-concave of a salient point and.
The manufacture method of thermal insulation brick made of polystyrene foam plastics, its step is as follows:
A, the polystyrene foam plastics that will reclaim from junk and rubbish with the poly-third plastic warp packaging bag, packing rope etc., are made needed particle diameter, length with mill, and generally between 5-20mm, length is between 30-150mm for particle diameter;
B, take by weighing polystyrene foam plastics, fibrous material, glue, air entrained agent, cement, early strength admixture, water reducing agent with measurement instrument by forming proportioning; Polystyrene foam plastics, glue, three error in dippings of cement are respectively less than 0.25kg, and fibrous material, air entrained agent, early strength admixture, the every error in dipping of water reducing agent are respectively less than 0.05kg;
C, the material for preparing are packed in the mixing plant, add water mixing stirring at normal temperatures, and the weight ratio of material and water is 1: (0.5-0.9), stir into various materials and dissolve together slip mutually uniformly;
D, slip are by conveying device each quantitative injection many types of chamber stock mould or whole big die cavity stock mould, filling with the back pressurization wipes off, after first stock mould annotated, original position is motionless, buttress is put second empty stock mould and is carried out injection molding more thereon, go round and begin again and repeat work, when buttress is put into absolute altitude, move on to the position work of next buttress;
E, slip carry out natural Health preservation under the normal temperature in stock mould, when a health 2-3 days slip condenses into solid, carry out the demoulding;
At normal temperatures, place again and dried curing in 4-7 days after f, the demoulding,, can cut into standard or off-standard size insulating brick as required by the large volume insulating brick of the big die cavity stock mould of integral body output.
The present invention has the following drawings:
Fig. 1 is a thermal insulation brick made of polystyrene foam plastics cross-sectional view of the present invention.
Fig. 2 is the structural representation that thermal insulation brick made of polystyrene foam plastics of the present invention is affixed on metope.
