Abstract
The invention belongs to the technical field of construction materials, and specifically relates to an adhesive for exterior wall thermal insulation boards. The adhesive is composed of the following components in parts by weight: 360 to 430 parts of cement, 550 to 600 parts of sand, 1.5 to 3 parts of polymer xanthan gum powder, 1.5 to 3 parts of hydroxypropyl methyl cellulose, and 5 to 20 parts of redispersable latex powder; wherein the cement and sand are the basic materials, and other components are additives. Due to the addition of redispersable latex powder, the waterproof performance of the mortar is enhanced, the adhesive can be used in a damp environment or in a rainy day, and the water tolerant property of the adhesive is also strengthened. Due to the addition of polymer xanthan gum power and hydroxypropyl methyl cellulosed, the viscosity of mortar is greatly increased, the water retaining effect of the adhesive is good, moreover the adhesive can slow the solidification speed, thus the operation time is prolonged, and the adhesive can be transported in a long distance. The raw materials of the adhesive are all solid particles or powder, and thus the adhesive is convenient to transport and can be stored for a long time.
Description
Technical field
The invention belongs to building materials technology field, be specifically related to a kind of caking agent for wall thermal insulation board.
Background technology
At present, along with the increasing of national building energy conservation dynamics, the use of wall thermal insulation board is also promoted thereupon, and is also applied day by day widely for the caking agent that heat preservation plate material is bonding with exterior wall.
Caking agent is a kind of according to different heat preservation plate material, chooses suitable additive, through the dry-mixed mortar that mixing, homogenizing are prepared from.Owing to being mixed with the additive of certain weight proportion in caking agent, therefore possesses the good performance such as bonding, water-fast, cold-resistant.
Existing heat preservation plate material is thermal insulation molded polystyrene foams plastics (EPS) and thermal insulation hormone polystyrene foamed plastics (XPS) two kinds mainly, molded polystyrene foams plastics (EPS) and thermal insulation hormone polystyrene foamed plastics (XPS) all belong to organic foam plastic, its surface is flexible body, and common caking agent is difficult to the effect reaching smooth strong bond.
Summary of the invention
Given this, technical problem to be solved by this invention is to provide the excellent caking agent bonding with body of wall for heat preservation plate material in insulating layer of external wall of building of a kind of adhesiveproperties.
For a caking agent for wall thermal insulation board, it is characterized in that, its each component and parts by weight are comprise base-material: cement 360-430 parts, 550-600 parts, sand; Additive: polymer xanthan rubber powder 1.5-3 parts, Vltra tears 1.5-3 parts, redispersable latex powder 5-20 parts.
Preferably, described cement is normal silicate 42.5 cement.
Preferably, described sand is common engineering 40-100 order quartz sands.
Get ordinary Portland cement in proportion, that sand, polymer xanthan rubber powder, Vltra tears, redispersable latex powder carry out mechanically mixing is even, add in clear water to stirrer in the ratio of weight of material 25-30% and carry out about 20 minutes uniform stirrings, the caking agent that workability is good, bonding strength is high can be obtained.
The present invention has following beneficial effect:
The present invention is on the basis of traditional sand-cement slurry, by the increase of additive, improve water-retentivity and the stickiness of mortar, emulsifying effect strengthens, the sagging resistance of mortar and ageing resistance and weatherable performance, can be that heat preservation plate material assertive evidence is firmly bonded on building exterior wall face effectively, avoid hollowing phenomenon and light caducous generation.Adding of polymer xanthan rubber powder and Vltra tears, significantly can improve the stickiness of mortar, its Water-saving effect is good, play the effect of slow setting, the operating time of operating personnel can be extended, can be suitable for longer-distance conveying, the intensity after sclerosis is high, avoids the heat preservation plate material after bonding and loosens or fall.The interpolation of redispersable latex powder, enhances the water resistance of mortar, also can construct under humidity and rainy weather, and the water resistance of the caking agent strengthened.
