Abstract

The invention provides air duct coating cloth for a coal mine. The air duct coating cloth consists of 50 percent of polyvinyl chloride (PVC)-3 resin, 6 to 13 percent of dioctyl-phthalate (DOP), 6 to 13 percent of dibutyl phthalate (DBP), 1 to 4 percent of epoxidized soybean oil, 4 to 8 percent of 52-DEG C chlorinated paraffin, 0.5 to 2 percent of antistatic agent (TC-90), 1 to 4 percent of antimonous oxide, 0.3 to 1 percent of dye black, 1 to 3 percent of stabilizing agent, and 10 to 20 percent of nano calcium carbonate. The technical scheme has the advantages that: the plastic coating cloth has anti-static electricity, tearing strength and other main indexes which are superior to those of the national industrial GB/T-20105-2006 standard of 'air duct coating cloth'; a heat seal surface after rolling is firm, a surface film and a bottom film at a connector of the plastic coating cloth are rolled and fused integrally, and the tearing strength is higher than that of the whole cloth; and the antistatic agent and fire retardant are fused in a PVC plastic high polymer material and do not volatilize, so that the coating cloth is environment-friendly, and does not have peculiar smell, and has good inflaming retarding and antistatic effects, and the service life which far exceeds that of the national standard.

Description

The ventilating duct coated cloth is used in a kind of colliery

Technical field

The present invention relates to the pit gear field, refer in particular to a kind of colliery and use the ventilating duct coated cloth.

Background technology

Mainly adopt when producing with two anti-plastics ventilating duct coated cloths in colliery in the market: high-strength imperial yarn woven fabric and the two-layer up and down PVC plastic film washed forms product under the situation of high temperature and pressure.The product that adopts this method to produce, the ubiquity following point:

1, static inhibitor adds film forming in the PVC raw material, and after heat compression moulding, product sticking power does not reach national standard again, and quality can not get guaranteeing.

2, after formed product, electrostatic agent evenly is applied to product subsurface, product sticking power temporarily is up to state standards, and quality is guaranteed.But the antistatic requirement of product does not reach the 1 year time of national standard defined, and static inhibitor is short, volatile in the time that product subsurface stops, pollute the related production personnel and cause health harm.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art, solve the contradiction between product sticking power and the antistatic effect, a kind of national product relevant criterion that both reached is provided, can make product life-time service under mine again.The static inhibitor that is about in the product adds in its raw materials for production before film forming, makes its product up to standard.

For realizing above-mentioned purpose; Technical scheme provided by the present invention is: a kind of mining ventilating duct coated cloth; It is black by PVC-3 type resin, DOP, DBP, epoxy soybean oil, 52 ° of chlorinated paraffins, static inhibitor, Antimony Trioxide: 99.5Min, nanometer grade calcium carbonate, dyestuff, stablizer is formed: wherein; Black 0.3 ~ 1%, the stablizer 1 ~ 3% of PVC-3 type resin 50%, DOP6 ~ 13%, DBP6 ~ 13%, 1 ~ 4%, 52 ° of chlorinated paraffins 4 ~ 8% of epoxy soybean oil, static inhibitor (TC-90) 0.5 ~ 2%, Antimony Trioxide: 99.5Min 1 ~ 4%, dyestuff, nanometer grade calcium carbonate 10 ~ 20%.

Described stablizer is Triple Pressed Stearic Acid, lead stearate, barium stearate, three salt, disalt; Static inhibitor is TC-90; Antimony Trioxide: 99.5Min; Dyestuff is a black.

A kind of colliery is put into pot with PVC-3 type resin earlier and is stirred 60S with the making method of ventilating duct coated cloth; Add 50% of DOP, DBP, epoxy soybean oil, 52 ° of chlorinated paraffin total amounts then, add 50% of stablizer total amount again, stir 60S; Add at last that nanometer grade calcium carbonate, dyestuff are black, Antimony Trioxide: 99.5Min, static inhibitor and remaining DOP, DBP, epoxy soybean oil, 52 ° of chlorinated paraffins and stablizer, stir 90S and form mixture; This mixture is poured in the funnel of mill, opened refining, put into extruding machine extrusion molding, calendering, applying, cooling then, form finished product ventilating duct cloth.

The advantage of this programme is: one, leading indicator such as antistatic, tear strength of the plastic coat cloth of this programme is superior to national industry GB/T-20105-2006 " air duct coated cloth " standard; Two, the heat seal face after the calendering is firm, and the calendering of the plastic coat cloth interface facial mask of this programme and counterdie fuses as a wholely, and tear strength is also higher than whole cloth intensity; Three, static inhibitor, fire retardant merge in PVC plastics macromolecular material, can not volatilize, environmental protection, free from extraneous odour, and fire-retardant, antistatic effect good, produce above national standard duration of service far away.

Embodiment

Be described further in the face of the present invention down, preferred embodiment of the present invention is: the described mining ventilating duct coated cloth of present embodiment is made up of PVC-3 type resin, DOP, DBP, epoxy soybean oil, 52 ° of chlorinated paraffins, static inhibitor, Antimony Trioxide: 99.5Min, nanometer grade calcium carbonate, dyestuff black (can adjust relevant colors according to requirement of client: as orange, grass green etc.), stablizer; Wherein, Black 0.3 ~ 1%, the stablizer 1 ~ 3% of PVC-3 type resin 50%, DOP6 ~ 13%, DBP6 ~ 13%, 1 ~ 4%, 52 ° of chlorinated paraffins 4 ~ 8% of epoxy soybean oil, static inhibitor (TC-90) 0.5 ~ 2%, Antimony Trioxide: 99.5Min 1 ~ 4%, dyestuff, the stablizer of present embodiment is Triple Pressed Stearic Acid, lead, barium, three salt, disalt; Nanometer grade calcium carbonate 10 ~ 20%.

The making method of accomplishing above-mentioned described mining ventilating duct cloth includes following steps:

At first, PVC-3 type resin is put into pot and stir 60S;

Add 50% of DOP, DBP, epoxy soybean oil, 52 ° of chlorinated paraffin total amounts then, 50% of stablizer total amount stirs 60S;

Add at last that nanometer grade calcium carbonate, dyestuff are black, Antimony Trioxide: 99.5Min, static inhibitor and remaining DOP, DBP, epoxy soybean oil, 52 ° of chlorinated paraffins and stablizer, stir 90S and form mixture; The mixture that forms has the sense of infiltration, and is tack-free and certain elasticity is arranged, can scatter by nature after unclamping.

Said mixture is poured in the funnel in the mill, opened refining, extrusion molding, calendering, applying, cooling, form finished product ventilating duct cloth.Wherein, the temperature of opening when refining is controlled at about 160 ℃, and the temperature during extrusion molding is divided four sections controls: first section is 110 ℃, second section and is 130 ℃, the 3rd section to be 150 ℃, the 4th section be 155 ℃; Temperature during calendering is controlled at 160 ℃ ~ 168 ℃; Temperature during applying is controlled at below 170 ℃.

The product of this programme production is black open width shape (can confirm color separately according to customer requirement); Relevant regulations according to GB/T-20105-2006 " air duct coated cloth " experimentizes; It is 2592 that this product warp-wise is pulled apart brute force, greater than GB >=2000 (N/50mm); It is 2308 that broadwise is pulled apart brute force, greater than GB >=2000 (N/50mm); Radially tear edge is 1210.9, be much higher than GB >=250 (N); The broadwise tear edge is 1243.2, be much higher than GB >=250 (N); Adhesion strength is 33.6, greater than GB >=30 (N/25mm); Other parameter all meets the GB relevant regulations, and the plastic coat cloth interface of this programme fuses as a wholely after rolling, and tear strength is also higher than whole cloth intensity; And static inhibitor, fire retardant merge in plastic material, can volatilization, environmental protection, free from extraneous odour.

The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
