Abstract

The utility model relates to a polyurethane composite heat preservation ceramic tile of an inner wall and an outer wall, which is characterized in that a surface layer is the ceramic tile, a middle layer is hard polyester form, a bottom layer is a strong fiber cement board, and the surface layer, the middle layer and the bottom layer are compounded into a whole at high temperature and high pressure. The ceramic tile has quick construction speed, simple operation, and high efficiency; because a hard foam polyurethane material is adopted to compound, the ceramic tile has stable porosity structure, good heat preservation performance and good sound absorption performance and, can resist freezing and thawing, and the average life of the outer heat preservation structure of the outer wall can reach above 25 to 30 years under the condition of normal use and maintenance.

Description

Polyurethane composite inside and outside wall temperature preservation ceramic tile

Technical field:

The utility model relates to a kind of polyurethane composite inside and outside wall temperature preservation ceramic tile, is a kind of novel building energy-saving decoration material.

Background technology:

The main polystyrene board thermal insulation board of pasting certain intensity and thickness on wall face of present construction wall insulation forms combined wall, and polystyrene thermal insulation plate and body of wall stickup are that cavity is pasted, stickup face has only about 30% usually, polystyrene board and wall outer side adhesive surface have nearly 70% cavity like this, can directly influence heat insulation effect, in case water inlet or generation aqueous vapor also can cause the corrosion of coming off of warming plate and body of wall, have a strong impact on the use in house, promptly can appear in the period of validity of building, need carry out once above maintenance or reconstruction to wall insulated board, this is obviously economical inadequately; Expandable polystyrene plate EPS can only be in 75 ℃ environment, to 80 ℃ will seriously shrink, extruded polystyrene plate XPS and expandable polystyrene plate EPS coefficient of thermal conductivity are 0.035～0.040W/ (m.K), and the bonding work progress of EPS and XPS and cement basic layer is loaded down with trivial details, need add professional glue several times, net, stones such as nail just can be finished.The common shortcoming of heat insulating material commonly used is that fireproof performance, endurance quality are relatively poor at present.

Summary of the invention:

The purpose of this utility model is to provide a kind of polyurethane composite inside and outside wall temperature preservation ceramic tile, its speed of application is fast, simple to operate, the efficient height, because it is compound to adopt the hard-foam polyurethane material to carry out, porosity Stability Analysis of Structures, excellent thermal insulation performance, and freeze thawing resistance, sound absorption might as well, the average life span of external wall outer insulation structure under the normal condition of using and keeping in repair, can reach more than the 25-30.

The technical solution of the utility model is achieved in that polyurethane composite inside and outside wall temperature preservation ceramic tile, it is characterized in that: surface layer is a Ceramic Tiles, and the intermediate layer is the hard polyester foam, and bottom is an one for the strong fiber cement board is compound through HTHP.

Good effect of the present utility model is waterproof, insulation, decorative lamination integration heat insulating material, low-density, low thermal conductivity, can resist rugged surrounding temperature; High strength, high-adhesion, and hard polyurethane foam stable chemical performance, acid and alkali-resistance; Agent of low hygroscopicity, avirulence, "dead", inanimate object parasitics; Excellent fireproof performance, oxygen index (OI) 〉=26; Good building performance can cut combination arbitrarily, and architectural construction technology is oversimplified, enhance productivity, and simple and fast, expense is low; Environmental protection and energy saving have realized building energy conservation more than 65%, and the multi-color of Ceramic Tiles and plurality of specifications reach high aesthetic property, make it have high cost performance.

The one, moistureproof, water resistance is good.The rate of closed hole of hard polyurethane foams reaches more than 95%, can be used in 100 ℃ the environment, add the heatproof auxiliary material after, serviceability temperature can reach 120 degree, hard polyurethane foam can satisfy the building materials flame-retardant standard of higher B1 of building thermal insulation material or B2 level.

The 2nd, coefficient of thermal conductivity is low.In existing heat insulating material so far, minimum 0.019～the 0.024W/ of the coefficient of thermal conductivity of this product (m.K), because hard polyurethane foams has very excellent heat-proof quality, the heat insulation effect of the hard polyurethane foams that 50mm is thick is equivalent to the thick EPS of 80mm, thick thick plank or the thick concrete of 760mm of cork, 280mm of mineral wool, 100mm that 90mm is thick.So suitable space has been saved in the application of hard polyurethane foams.

The 3rd, hard polyurethane foam is compared better than EPS with the adhesive property of cement basic layer, makes " outer heat insulation facing system " with wall face firm adhesive property be arranged, and this product can directly stick on the wall with cement by the composite powerful fiber cement board in addition.

Four hard-foam polyurethane materials can meet domestic and the requirement of every standard in the world.It can not resemble the phenomenon that the fusing drippage is arranged EPS or the XPS material, and the hard-foam polyurethane material is in combustion process, can form spreading that the topping of a coking suppresses to burn.The Ceramic Tiles face of joining then can further strengthen its fire resistance.

The 5th, the compressive strength height.Hard polyurethane foams has higher compressive strength, caking property and shear strength.And the intrinsic intensity of polyurethane material itself is passed through and Ceramic Tiles, and the strong fiber cement board forms composite construction and is further strengthened.

Six environmental protection and energy saving.Environmental protection, it does not contain formaldehyde, so can not pollute harm to environment; It is not subjected to the invasion and attack of bacterium and microorganism simultaneously, has neutral microbiologic properties.Energy-conservation, the independence building that a building adopts polyurethane composite inside and outside wall heat preservation ceramic tile to carry out roof heat insulation is carried out modeling of energy conservation calculating, the result proves, uses the hard polyurethane foams of 1m3, WLG025, can save the energy of 6.55 ten thousand kwh in 50 years.Produce the required energy of hard polyurethane foam (house come into operation after only 8 months) in first heating phase and just can obtain recovery.

Seven construction simple and fasts.Polyurethane composite inside and outside wall heat preservation ceramic tile can disposablely be finished bonding with body of wall, insulation, and the surface is beautified.Make unit in charge of construction shorten the duration greatly, economize the people, the saving of labor saves time, and is laborsaving.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, polyurethane composite inside and outside wall temperature preservation ceramic tile, it is characterized in that: surface layer is a Ceramic Tiles 1, and the intermediate layer is a hard polyester foam 2, and to be strong fiber cement board 3 be one through HTHPs are compound to bottom.

When using that the strong fiber cement board 3 of this polyurethane composite inside and outside wall temperature preservation ceramic tile is directly sticking or direct and body of wall is bonding with cement with exterior wall bonding powder point, can the omnibearing heat insulation effect of construction bond complex region, can prevent the restriction of sealing or steam again to the body of wall condition.Because it is compound to adopt the hard-foam polyurethane material to carry out, the porosity Stability Analysis of Structures is closed pore basically, so not only excellent thermal insulation performance, and freeze thawing resistance, sound absorption, the average life span of external wall outer insulation structure, under the normal condition of using and keeping in repair, can reach more than the 25-30.
