Abstract
The invention discloses a preparation method of fireproof smoke-suppressing PVC synthetic leather. The PVC synthetic leather is prepared by tightly compositing a polyurethane fabric layer, a PVC layer, a glass fiber cloth bottom layer from top to bottom, wherein the PVC layer is prepared through the steps of blending PVC, a plasticizer, tris(2-chloroethyl) phosphate, epoxidized aliphatic ester, aluminium hydroxide, magnesium hydroxide, a barium zinc stabilizer and PVC color paste into mixed paste with certain viscosity and drying the mixed paste. The preparation method comprises the following steps: preparing the mixed paste, drying the mixed paste to obtain the PVC layer, bonding the polyurethane fabric layer, PVC layer and glass fiber cloth bottom layer into a whole by using the mixed paste step by step, drying, and trimming, so as to obtain the PVC synthetic leather. The PVC synthetic leather is fireproof, thermal-insulating and sound-insulating, suppresses smoke, and is more ideal in use effect.
Description
Technical field
The invention belongs to artificial leather production technical field, relate to PVC synthetic leather production technical field, particularly a kind of fire prevention presses down the preparation method of the PVC synthetic leather of cigarette.
Background technology
At present, the range of application of synthetic leather says benefit extensively, but the application in building trade is at the early-stage, be mainly used in the inner wall decoration of household and place of public amusement, the inner wall decoration of place of public amusement presses down cigarette and there are certain requirements heat insulation, sound insulation, fire prevention, the fire-retardant PVC synthetic leather of prior art, its fire retardant normally adds antimonous oxide fire retardant, antimonous oxide is the fire retardant applied the earliest, and when being used alone, consumption is large, and flame retardant effect is poor; When with halide (R.HX) and the used time then have good cooperative effect, flame retardant effect is obvious.
The fire-retardant PVC synthetic leather of prior art, can use certainly, but only prevent fires not press down the inadequate Environmental Safety of cigarette, have impact on the use of synthetic leather in building trade to a certain extent.Smog to produce at first and the most lethal and affect the factor on fire fighting opportunity adversely in a fire, death toll according to statistics in fire have 80% be suffocate caused by, so it is more even more important than " fire-retardant " " to press down cigarette " to the PVC synthetic leather of building trade application, the fire-retardant PVC synthetic leather of prior art is only prevented fires and is not pressed down cigarette, heat-insulating sound-insulating heat insulation effect is also poor, and its fire retardant used is from bibliographical information, has carcinogenic possibility, result of use is desirable not enough.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the preparation method that a kind of fire prevention presses down the PVC synthetic leather of cigarette.
The present invention for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of fire prevention presses down the preparation method of the PVC synthetic leather of cigarette, described PVC synthetic leather from top to bottom by polyurethane fabric layer, polyvinyl chloride layer, glass fabric bottom totally three layers be closely composited; Wherein, described polyvinyl chloride layer makes after being dried by the mixed paste of polyvinyl chloride, plasticizer, three (2-chloroethyl) phosphate, epoxy aliphatic ester, aluminium hydroxide, magnesium hydroxide, barium zinc stabilizer, polyvinyl chloride color; Described preparation method comprises the following steps:
Steps A, preparation mixed paste; The preparation of mixed paste utilizes DOTP, as plasticizer, the mixed material of polyvinyl chloride, three (2-chloroethyl) phosphate, epoxy aliphatic ester, aluminium hydroxide, magnesium hydroxide, barium zinc stabilizer, polyvinyl chloride color is diluted to the mixed paste that viscosity number is 1500-3000cps; Wherein:
The weight portion of polyvinyl chloride: 100 parts;
