The specific embodiment

The utility model embodiment as shown in Figures 1 to 3, the cross-laminated high-polymer self-adhesion waterproof coiled material of this response type, it is characterized in that comprising basic unit and composite bed 3, basic unit consists of modified pitch 2, is provided with tire base 1 in basic unit, and tire base 1 is scrim, as chemical fibre fabric, natural plants fabric or composite fibre etc., composite bed 3 consists of the HDPE film of two-layer above crosswise lamination, and the present embodiment is selected 3 layers, and adjacent HDPE film is to tilt 45 degree crosswise laminations.The manufacturing process of the cross-laminated high-polymer self-adhesion waterproof coiled material of this response type is as follows, and each component calculates by mass parts:

A, prepare modified pitch, pitch is placed in retort, heat to 140 ℃ of-150 ℃ of dehydrations, add random polypropylene and SBS, be mixed evenly, temperature is controlled at 180 ± 5 ℃, stir 1-1.5h, make modified pitch; The each component ratio is 100 parts of pitches, random polypropylene 2-5 part, 4-8 part SBS;

B, add antioxidant, filler, function additive, tackifier in retort, stir 0.5-1h, carry out fully mixed and modified; The each component ratio is: modified pitch 45-55 part that step a makes, antioxidant 0.5-1 part, filler 35-45 part, function additive 0.2-0.3 part, tackifier 2-5 part;

C, by colloid mill, to obtaining material in the b step, grind, then dip-coating on the tire base, control thick typing, cover composite bed, rolling after cooling, bonding after being covered with separation layer in basic unit and preventing from rolling up.

Wherein said tackifier are asphalt powder or butylbenzene pitch or terpene resin; Modifier is random polypropylene and SBS; Antioxidant is the antioxidant TNP trisnonyl phenyl phosphite; Function additive is alkyl alcohol polyoxyethylene ester condensates; Filler is dicalcium powder, talcum powder or flake asbestos.

SBS SBS in modifier is the class modified asphalt material that cost is lower, application is wider, SBS SBS modified pitch, has good hot strength, skin-friction coefficient is large, cryogenic property is good, the characteristics such as good processability; Random polypropylene APP belongs to the plastomer modified agent, can form unique linear network structure in asphalt, can significantly improve the resistance to elevated temperatures of modified pitch, simultaneously to cryogenic property, and tensile strength, extension property also has good modification performance.The application of antioxidant antioxidant TNP and functional aid alkyl alcohol polyoxyethylene ester condensates, can realize modified pitch and concrete generation chemical reaction.The primary condition that can mutually bond securely between two kinds of different materials is: the surface both performance is identical or close, can be affine mutually.But the different materials that uses in the application process of cold bonding waterproof material, pitch are the organic matters of the faint polarity of a kind of only tool, water resistant oleophylic; Various concrete or cement mortar are all to have the inorganic matter of natural affinity, the strong polar surfaces of tool with moisture,, so be incompatible mutually between the two, certainly can not mutually bond securely.Alkyl alcohol polyoxyethylene ester condensates is a kind of take nonionic as main surfactant.The terminal polar group that has simultaneously in their molecules and nonpolar end group, have extremely strong adhesion with the molecule of concrete and pitch respectively.Existence due to alkyl alcohol polyoxyethylene ester condensates, just erected a molecule bridge that connects each other between pitch and concrete two interfaces, make affine, the closely adhesion mutually of two kinds of mutual incompatible storerooms by it, thereby formed function and the effect of anti-strip.The modified pitch and the concrete surface that have added alkyl alcohol polyoxyethylene ester condensates form physical absorption and rely on its special chemical constitution to make itself and concrete carry out combination reaction, form powerful chemical tie between them, thereby modified pitch and concrete adhesiveness have been improved, make it have good resistance to heat aging and water resistance, extend the service life of waterproof roll.

The utility model waterproof roll and cement or concrete reaction and bonding mechanism: the size of concrete and modified pitch adhesion derives from absorption, infiltration and the capillarity of modified pitch at concrete surface; Modified pitch is that mechanical adhesion power is larger in the degree of sprawling of concrete surface to the opposing of water stability, more is not subject to the impact of water; Modified pitch can represent with contact angle and spreading coefficient in the degree of sprawling of concrete surface, alkyl alcohol polyoxyethylene ester condensates can make the water stability of modified pitch improve, because alkyl alcohol polyoxyethylene ester condensates is a kind of surfactant, it can make modified pitch diminish at the contact angle of concrete surface, and modified pitch improves in the degree of sprawling of concrete surface; The operation principle of alkyl alcohol polyoxyethylene ester condensates is in modified asphalt waterproof coiled material and concrete base layer carry out bonding process, the hydrophilic polar of concrete surface is converted into neutrality, before and after reaction, as shown in Figure 2,3, modified pitch and concrete generation chemical reaction form cross-linked structure and produce bonding concrete surface character.When installation of membrane behind concrete surface, concrete generates in the hydration reaction process hydrated calcium silicate (C-S-H gel) and calcium hydroxide, chemical equation is as follows:

3CaO·SiO2+nH2O＝xCaO·SiO2·yH2O+(3-x)Ca(OH)2

There is the Si-OH group in concrete, contain TMOS in the lower surface glue-line that waterproof roll contacts with concrete, it and concrete joint react after touch, generation has the hydroxyl of reactivity, hydroxyl in this activity hydroxy and Si-OH group reacts, generate ehter bond, make gel of calcium silicate and coiled material top layer form chemical bond and firmly link together.This cementation is very firm, affected by the environment for use factor of coiled material less, thereby it can be bonded on basal plane enduringly, and with basal plane, forms full bonding structure.

Composite bed adopts the density polyethylene film with high of crosswise lamination as facing material, and this material adopts the oblique 45 degree stacks of density polyethylene film with high to intersect and makes, and has higher tearing strength and dimensional stability, and water resistance more is better than general thin.

The utility model can be used for the waterproofing work of the hidden environment such as basement, needs can cover and add the metal aluminum foil layer while implementing for the waterproofing work of the exposed environment such as roofing on composite bed, aluminium foil layer covers the polyester rete outward, this facing material has higher tearing strength and dimensional stability, protection against the tide, oxygen barrier, shading, shielding, antistatic, water resistance more is better than general thin, solved simultaneously aluminium foil self tearing strength little, very easily tear, the easy problem of oxidation, the service life of improving aluminium foil.
