Description
Technical field
The present invention relates to the manufacture technology field of the composite with fire-retardant, waterproof, airing function.
Background technology
The heat-insulating property of heat-preservation cotton in the market, the outer diaphragm of rock wool is poor, and in addition, easily spread when naked light, its fire safety performance is poor, can not adapt to the demand of modern industry or building.
Summary of the invention
The present invention seeks to propose a kind of preparation method with the fire-resistant waterproof ventilation pad of fire-retardant, waterproof, airing function,
The present invention includes following steps:
1) after polypropylene H2800, metallocene PE, Exxon Mobil elastomer PP6002, nano-calcium carbonate, coupling agent, dispersant, lubricant and chlorinated paraffin wax being mixed, through double-screw extruding pelletizing, then form sheet material through curtain coating, cooling, finally by sheet material by adding hot-stretch, cooling and shaping makes copolymerization microporous barrier;
2) by two the surperficial hot pressing polypropylene non-woven fabrics of hot roll at copolymerization microporous barrier, three-in-one semi-products are formed;
3) after three-in-one semi-products being flooded the mixed impregnant liquor including fire retardant, hydrophilizing agent and silane coupler JS-D758, dry through drying cylinder, form fire-resistant waterproof ventilation pad.
The product gone out by above explained hereafter is applicable to metal Roof, pitched roof; layer protecting film outside heat-preservation cotton, rock wool, the permeability performance of its uniqueness, makes the inner aqueous vapor of fabric structure discharge rapidly; protection property value, and ideally solve protection against the tide and people's health in residential environment.When breaking out of fire, its fire resistance can be manifested, toxic gas can not be produced, simultaneously because fire retardant has good one-tenth charcoal effect, polypropylene becomes charcoal with blend fusion and decomposition, can reduce fire damage.
The present invention has the following advantages and feature.
1, the present invention adopts the polymeric matrix of polypropylene H2800, metallocene PE, Exxon Mobil elastomer PP6002 blend, instead of traditional polyethylene support, solve the resistance to temperature problem of copolymerization microporous barrier, make the copolymerization microporous barrier close with polypropylene fusing point, instead of external imported product, production technology easily controls, be convenient to batch production, and yield rate is high.
2, its fire resistance is when breaking out of fire, can not produce toxic gas, simultaneously because fire retardant has good one-tenth charcoal effect, polypropylene becomes charcoal with blend fusion and decomposition, can reduce fire damage.
3, ultralight, fire-resistant waterproof ventilation bed course of the present invention every square metre of quality is only 80 ~ 200 grams,
4, ultra-thin, fire-resistant waterproof ventilation cushion thickness of the present invention only has 0.2 ~ 0.6MM
5, easy construction, while the liquid phase water that metal Roof, pitched roof prevent building external to infiltrate and vapour phase water, makes again the steam of heat-insulation layer emit rapidly.
6, fire-resistant waterproof ventilation pad of the present invention freely can be breathed, has perspiration functions, not possess growth of microorganism environment, mould fungus inhibition grows.
In step 1) of the present invention, the mass ratio that feeds intake of polypropylene H2800, metallocene PE, Exxon Mobil elastomer PP6002, nano-calcium carbonate, coupling agent, dispersant, lubricant and chlorinated paraffin wax is 30 ~ 50 ︰ 10 ~ 30 ︰ 20 ~ 30 ︰ 100 ~ 150 ︰ 2 ~ 4 ︰ 1 ~ 2 ︰ 2 ~ 4 ︰ 2 ~ 4.
In described step 1), the film thickness that curtain coating is formed is 0.080 ~ 0.11mm.
When cooling in described step 1), employing surface temperature is the cold roller of 10 ~ 20 DEG C.
Add hot-stretch in described step 1) and be through level Four stretching, the velocity ratio that first, second and third and level Four stretch is 1 ︰ 1.4 ~ 1.8 ︰ 1.6 ~ 2.5 ︰ 2.2 ~ 3.5 ︰ 3.2 ~ 3, and first, second and third grade of draw speed progressively increases progressively, fourth stage speed is lower than third level draw speed; Temperature when first, second and third grade stretches is also in progressively increasing progressively, and temperature when first, second and third and level Four stretching is respectively 40 ~ 60 DEG C, 50 ~ 80 DEG C, 80 ~ 100 DEG C, 70 ~ 60 DEG C.
In described step 1), cooling and shaping adopts surface temperature to be the cold roller of 10 ~ 20 DEG C.
Described step 2) in, after first copolymerization microporous barrier being passed through 80 ~ 100 DEG C of preheatings, be 0.3 ~ 0.5MPa at pressure, surface temperature is compound in the hot roll of 100 ~ 130 DEG C.Because the Main Ingredients and Appearance of copolymerization microporous barrier is polypropylene H2800, metallocene PE and Exxon Mobil elastomer PP6002, close, the main material molecule of the fusing point of three kinds of materials is close, so the pressure of compound tense breaker roll machine and temperature requirement lower, temperature is generally under polyacrylic fusing point, so the temperature that combination process requires is low, be beneficial to energy-saving production.The invention solves in the past that the resistance to temperature of copolymerization microporous barrier is low simultaneously, easily cause the phenomenon of perforation in the process of hot pressing.
In described step 3), described fire retardant accounts for 20 ~ 35% of mixed impregnant liquor gross mass.
Detailed description of the invention
One, production copolymerization microporous barrier:
1,30 ~ 50kg polypropylene H2800 is taken respectively, 10 ~ 30kg metallocene PE, 20 ~ 30kg Exxon Mobil elastomer PP6002,100 ~ 150kg nano-calcium carbonate, 2 ~ 4kg coupling agent, 1 ~ 2kg dispersant, 2 ~ 4kg lubricant, 2 ~ 4kg chlorinated paraffin wax.
Wherein, coupling agent can adopt Aluminate or titanate esters; Dispersant is organic dispersing agent, as polyacrylamide; Lubricant can adopt OPE.
2, after adopting high-speed mixer to mix above material, adopt double-screw extruding pelletizing, again through drying and processing after granulation, form pellet.
3, pellet is passed through extruder, formation casting thickness is 0.080 ~ 0.11mm, width is the film of 1.8 ~ 2.0m, is then the cold roller cooling and shaping of 10 ~ 20 DEG C through surface temperature, so that copolymer cools rapidly formation sheet material.
4, cooled sheet material is added hot-stretch through level Four, make the copolymerization microporous barrier that width is 1.5 ~ 1.6m.
Wherein, the velocity ratio that first, second and third and level Four stretch is 1 ︰ 1.4 ~ 1.8 ︰ 1.6 ~ 2.5 ︰ 2.2 ~ 3.5 ︰ 3.2 ~ 3, and first, second and third grade of draw speed progressively increases progressively, and fourth stage speed is lower than third level draw speed, so that copolymer membrane resilience.Temperature when first, second and third and level Four stretching is also in progressively increasing progressively, and temperature when first, second and third and level Four stretching is respectively 40 ~ 60 DEG C, 50 ~ 80 DEG C, 80 ~ 100 DEG C, 70 ~ 60 DEG C.
5, by copolymerization microporous barrier through surface temperature be the cold roller cooling shaping type of 10 ~ 20 DEG C again, form copolymerization microporous barrier.
Two, compound:
1, the copolymerization microporous barrier of cooling and shaping is preheated to 80 ~ 100 DEG C.
2, be 0.3 ~ 0.5MPa by pressure, surface temperature be the hot roll of 100 ~ 130 DEG C at two surperficial hot pressing polypropylene non-woven fabrics of copolymerization microporous barrier, form three-in-one semi-products.
Three, flame treatment:
1, fire retardant, hydrophilizing agent, silane coupler JS-D758 and water are mixed in dipping tank, forming fire retardant quality accounting is the mixed impregnant liquor of 20 ~ 35%.
2, three-in-one semi-products are pulled through from mixed impregnant liquor, drier through drying cylinder, form fire-resistant waterproof ventilation pad.
Owing to adding chlorinated paraffin wax in production copolymerization microporous barrier, this mixed impregnant liquor does not act on copolymerization microporous barrier, copolymerization microporous barrier can not absorbing fluid, and only has polypropylene fibre in non-woven fabric component to have hydrophily, so the non-woven fabrics of extexine is then provided with fire resistance.
3, rolling, cuts into rouleau, packaging.
