Description
Technical field
The present invention relates to waterproof roll field, more particularly to a kind of non-bituminous base reaction-type flame-retarding polymer membranes and
Its preparation method.
Background technology
As the development of Building Trade in China, buildings waterproof market are increasing, traditional water proof roofing sheet is mainly adopted
The modified asphalt waterproof coiled material of hot melt application, modified asphalt waterproof coiled material has good hydrophobicity, cohesiveness and ductility, energy
Acid and alkali resistance, the corrosion of salt, shock resistance is preferable, low price, therefore is widely used.But modified asphalt waterproof
Coiled material is heated easy aging embrittlement, and cement roof or the inconsistent easy aliquation that expands with heat and contract with cold of metal Roof, big by construction infection,
The protection time limit is short.In addition, often have larger smell during use containing noxious materials such as naphthalene, anthracene, pyridine, phenol in pitch, it is dirty
Dye environment, it is irritant to skin and mucosa, there are light toxic action and carcinogenesis.China has gradually limited pitch class waterproof roll
Use range.
Existing non-bituminous response type waterproof roll in the market, be with high density polyethylene as base material,
Special PUR is scratched on HDPE sheet materials, then PUR surface sprinkle it is a kind of with white cement as primary raw material prepare
Granular " reaction sand ", a kind of overlap edge new type waterproof coiled material by made by barrier film is covered, this waterproof roll surface it is " anti-
Answer sand ", chemical crosslinking can occur with cast-in-place concrete and physics mortise and tenon is together solidified to form one, moisture can be entirely prevented
Penetrate between waterproof roll and structure, do not affected by basic unit's displacement, fundamentally prevent the disadvantage of " channeling water ".But this volume
Due to introducing " reaction sand ", coil weight is significantly increased material, and cost of transportation substantially rises, constructing operation burdensome, and
" reaction sand " partial exfoliation of coiled material surface is often resulted in transport work progress, waterproof effect is had a strong impact on；In addition, HDPE
Sheet material is generally thick in 0.8mm～1.5mm, and quality is harder, and when face position is bent at the right angles such as bag " negative and positive angle ", operation is extremely not
Just, sealing is also had a greatly reduced quality, and in addition the cost of this kind of coiled material is generally higher, it is promoted the use of also totally unfavorable.
Chinese patent CN 201510418180.X disclose a kind of non-bituminous Multifunctional water-proof coiled material laminated adhesive, application and

13～18 parts of calcium, 2～5 parts of tackifying resin, 0.1～0.4 part of coupling agent, 0.3～1.5 part of defoamer；Non-bituminous multifunctional water-proofing
Coiled material, the laminated adhesive for intersect film by strength, intersecting on film located at strength, the barrier film on laminated adhesive are constituted；The invention is special
The laminated adhesive of profit exploitation, coordinates strength to intersect film, and made non-bituminous waterproof roll is very frivolous, to all kinds of special-shaped basal planes
Paving is very convenient, can self-adhesion, pre-installed and inverted adhered can occur hydration reaction with cement basal plane, and water resistance is excellent.But, according to
Up to four layers of non-bituminous waterproof roll structure made by the method, laminated adhesive needs to coordinate strength intersection film and barrier film to reach
To effective effect, manufacturing process is loaded down with trivial details, improves manpower, goods and materials cost and production cycle.
