Problems solved by technology

[0002] At present, the size of the tarpaulin used in railway transportation is too small (9.1m×5.5m). An open car needs two or three tarpaulin covers. Reinforcement with hemp rope or hemp rope net is a waste of manpower and material resources; for decades, the traditional tarpaulin production process is backward and all are processed by industrial sewing machines, which is inefficient and labor-intensive. Waterproof glue is a waste of man-hours; the waist and side ropes on the tarpaulin are all made of hemp rope, which is natural arrow hemp. The supply of raw materials is tight, the price is high, and the service life is short

Embodiment Construction

[0020] The best embodiment of the present invention will now be described in detail with reference to Figure 1:

[0021] A kind of high-strength chemical fiber plastic coated tarpaulin is shown in Figure 1. It is composed of a thatch cloth 1 and the edge rope 2 and waist rope 6 tied to it. The thatch cloth 1 is rectangular with three 17200×1833mm double-sided artificial leather. Frame 8 is connected, processed into an area of ​​94.6m 2 There is a hemming rope 2 on the periphery of the tom cloth, five reinforcing ribs 7 are arranged in the middle, a rope threading cloth 3 is arranged at the junction of the reinforcing ribs 7 and the panel 8, and a waist rope 6 is worn in the rope threading cloth 3 , There are big triangles 5 on the four corners of the thatch 1, and small triangles 4 on the long sides for reinforcement.

[0022] The base fabric of the double-sided artificial leather of the present invention adopts interwoven fabric 5732 or 5736, and the side rope and waist rope adop...

Abstract

A high-strength chemical-fiber paulin coated plastics and its manufacturing method. The paulin comprises a tarpaulin, side ropes and wrist ropes thereof. The tarpaulin is quadrate and is made up of atwo-side leatheroid. There have side ropes around the tarpaulin, and fortified strings in the middle thereof. The side ropes and the wrist ropes are polypropylene-polyethylene ropes. Instead of the traditional processing method by a sartorius, A polypropylene-polyethylene rope replaces a hemp rope, a high-frequency soldering method or a weld pressing method is adapted. A truck paulin could replace at least two tarpaulin to cover goods. The paulin of the invention could resist water, flame, low temperature, and comes up to requirements of TB / T1941-1999 of Ministry of railways.

Description

Technical field [0001] The invention relates to a tarpaulin and a manufacturing method thereof, and is particularly suitable for high-strength chemical fiber plastic-coated tarpaulins for railway freight cars. Background technique [0002] At present, the size of the tarpaulin used in railway transportation is too small (9.1m×5.5m). A convertible car needs two or three tarpaulin covers. The tarpaulins are not tightly overlapped, and rainwater often penetrates to cause wet damage to the cargo. In addition, it needs Reinforcement with hemp rope or hemp rope net is a waste of manpower and material resources. For decades, the traditional tarpaulin manufacturing process is backward, and it is processed by industrial sewing machines. The efficiency is low and the labor intensity is high. The needle hole of the processed tarpaulin needs to be brushed for water leakage. Waterproof glue wastes man-hours; the waist and side ropes on the tarpaulin all use hemp rope, which is natural arrow h...
