Description

Waterproofing membrane with temperature indicator strip

Technical Field

The utility model belongs to the technical field of waterproofing membrane, especially, waterproofing membrane with temperature indication strip.

Background

There are two types of commonly used waterproof rolls, one is SBS (modified asphalt waterproof roll) type, and the other is polymer type (polyethylene polypropylene); the general practice of SBS (modified asphalt waterproof roll) is as follows: 1. brush base layer treating agent: the base layer base oil plays a role in cleaning the base layer and improving the bonding strength of the coiled material, the base layer is required to be fully brushed, the thickness of the base layer is moderate, the base layer is seen through too thin, the base layer is too thick and is not easy to volatilize, the construction time is influenced, tools of the base layer can be coated with rolling brush scrapers uniformly, the phenomena of missed brushing spots and the like do not exist, the coating direction is from far to near, and the construction can be carried out by people after all the base layer base oil. Note: the engineering foundation pit basically has no underground water, and the bottom surface base course treating agent can be brushed only on the slope surface and the surface of the brick bed film without brushing. 2. Laying of coiled materials: according to the arrangement of the engineering underground base layer, the coiled material is paved between the base layer of the bottom plate and the coiled material and is constructed by adopting a hot melting method, and the part provided with the asphalt covering layer of the coiled material is constructed by adopting hot melting full adhesion; after the direction is selected, the complex part is reinforced, a coiled material additional layer is made on all the internal and external corners with the angle not more than 135 degrees, a 500-width additional layer is made on the internal and external corners at the joint of the base layer and the vertical surface, the coiled material with the diameter not less than 30mm is applied to the position of the wall-penetrating sleeve, the joint is stretched into the pipe and sealed, the coiled material is divided into sawteeth by the pipe orifice and paved around, the diameter of the coiled material outside the joint is not less than 15mm, and then the sealing is carried out to be consistent with the coiled material on the vertical surface. 3. The complex parts are processed completely, the coiled material is rolled up from two ends to the middle after being placed in the right direction, a blowtorch is used for hot melting and unfolding from two ends, the coiled material is pushed by hands to be compacted, the phenomena of hollowing and wrinkle removal are avoided, the baking time is not too long, the base is not damaged by baking, a small amount of grease is preferably overflowed from two sides of the coiled material, the lap joint of each side is not less than 100mm, and the construction is carried out by adopting a hot melting full-adhesion method between the coiled material and the coiled material. The distance between the front and the back of the lap joint of the two rows of coiled materials is one third of the length of the coiled materials, and the transverse lap edges of the large surface of the bottom plate are staggered by more than 1500 mm. 4. When the first layer of coiled material is paved on the edge of the structural wall, 300mm of coiled material is reserved upwards according to the height of the structural wall to be jointed with the vertical surface of the upper structural wall, and the reserved empty coiled material is pressed on the wall surface by using bricks and cannot be torn off under other conditions. After the first layer is laid, the edge is gradually sealed, and the raised edge cannot be formed. Hollowing occurred and was found to occur immediately before handling for a second coil lay. 5. The second laying direction is the same as that of the first laying direction from west to east, but seams of the coiled materials are staggered and cannot be sewn again, the two staggered seams are not less than 400-600 mm, and the turned edges of the structural walls on the two sides are 500mm away from the turned edges and are pressed together with the first laying direction for later use.

The construction method of SBS (modified asphalt waterproof coiled material) in the prior art adopts the hot melt method, namely, the position of the asphalt covering layer of the coiled material is heated, and then the heating and laying are carried out, the method of heating and laying generally depends on the hot melt experience of laying workers, but because the hot melt is pasted by manual visual inspection, whether the asphalt covering layer is heated by a hot melt gun or not can not be judged, and the asphalt covering layer of the workers can be heated unevenly due to work fatigue, or some places do not reach the heating point completely, so that the laying generates bubbles, the laying adhesion degree is reduced, the laying quality is greatly reduced while the laying efficiency is influenced. There is an urgent need for a waterproofing sheet having temperature indicator strips that visually indicate that the asphalt overlay has reached its hot melt-full tack state.

No patent documents relevant to the present application were found by search.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide a simple structure, design benefit can ensure the hot melt and fully glue the waterproofing membrane that has the temperature indicator strip that thoroughly just can direct range estimation waterproofing membrane asphalt blanket's the heating condition.

The utility model provides a its technical problem take following technical scheme to realize:

the utility model provides a waterproofing membrane with temperature indication strip, is the child base by polyester felt, glass fiber felt or glass fiber reinforcement polyester felt, and styrene-butadiene styrene (SBS) thermoplastic elastomer forms the pitch overburden as pitch modifier, the child base sets up on the pitch overburden, it has transparent barrier film to paste respectively to cover at the upper surface of child base and pitch overburden lower surface, it is provided with the temperature indication strip still to equipartition interval on the pitch overburden between pitch overburden and transparent barrier film.

Moreover, the temperature indication strip is temperature color-changing resin, and the temperature color-changing resin is thermosensitive ink.

Further, the color change temperature of the thermal ink was 78 ℃.

The utility model has the advantages that:

the utility model discloses the interval is provided with the temperature indicator strip on asphalt covering layer, when carrying out the high temperature and toast full abdomen and spread, can come the snap judgments through the condition of discolouing of looking over the temperature indicator strip and whether can realize pasting totally to asphalt covering layer heating to the realization is even to asphalt covering layer heating, lays and pastes more firmly, has improved full efficiency of spreading greatly.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

A waterproof coiled material with a temperature indicating strip is characterized in that a polyester felt, a glass fiber felt or a glass fiber reinforced polyester felt is used as a base 2, a styrene-butadiene (SBS) thermoplastic elastomer is used as an asphalt modifier to form an asphalt covering layer 3, the base is arranged on the asphalt covering layer, and

transparent isolating films

1 and 4 are respectively attached to the upper surface of the base and the lower surface of the asphalt covering layer;

temperature indications 5 are uniformly distributed on the asphalt covering layer between the asphalt covering layer and the transparent isolating membrane at intervals, the temperature indication strips are temperature color-changing resin, the temperature color-changing resin is thermal ink, also called temperature indicating ink, the color-changing temperature is 78 ℃, when flame of the hot melting gun passes through the temperature indicating ink, the temperature exceeds 78 ℃, and therefore the temperature indicating ink can change color due to heating, and the fact that the asphalt covering layer of the hot melting gun is heated at high temperature is proved.
