The inventiondiscloses a method for manufacturing the multifunctional polyurethane rubber-enclosing sling. The method comprises the following steps: 1, selecting raw materials, namely selecting polyurethane rubber and the sling (1) as the raw materials; 2, determining the sizes of the sling and the polyurethane rubber layer (2) according to the loads of hoisted objects; 3, arranging a template to set up a mould according to the size of the polyurethane rubber layer (2) determined in the step two; 4, pouring the polyurethane rubber into the mould and coating the polyurethane rubber on the surface of the sling (1) after setting up the mould, and then cooling the mould to form the polyurethane rubber layer (2) on the surface of the sling (1); and 5, trimming two sides of the sling (1) to obtain a finished product.
Description
Technical field
The present invention relates to a kind of multifunctional polyurethane rubber-enclosing sling and preparation method thereof.
Background technology
Present suspender belt adopts the braiding suspender belt when the lifting object, but because the object that is hung is harder, therefore be easy to scratch braid, the damage owing to suspender belt causes safety misadventure easily in the process of lifting like this, and the mass ratio of hanging belt is relatively poor, and service life is short.
Summary of the invention
The invention provides a kind of multifunctional polyurethane rubber-enclosing sling and preparation method thereof, prepared suspender belt not only quality is good, is difficult for being scratched, and can improves the safety performance in when lifting.
The present invention has adopted following technical scheme: a kind of multifunctional polyurethane rubber-enclosing sling, and it comprises suspender belt, the surface of described suspender belt is provided with the Polyurethane glue-line.
Described Polyurethane glue-line is positioned at the centre portion of suspender belt.Described Polyurethane glue-line is positioned at the one side of suspender belt or two-sided.
The invention also discloses a kind of method for making of multifunctional polyurethane rubber-enclosing sling, it may further comprise the steps: step 1, and choose raw material: choosing Polyurethane glue is raw material; Step 2 is determined the size of suspender belt and the size of Polyurethane glue-line according to the load of institute's hoisting object; Step 3 is arranged template according to the Polyurethane glue-line size of determining in the step 2 then and is carried out formwork erection; Step 4 pours into polyurethane adhesive in the mould behind formwork erection and applies on the suspender belt surface, and then cools off, and so just forms the Polyurethane glue-line on the suspender belt surface; Step 5 is carried out deburring to the both sides of suspender belt and is handled, and obtains finished product.
Described Polyurethane glue comprises mark, polyester and TTR80 glue, and mark accounts for 10-12%, and polyester accounts for 60-70%, and TTR80 glue accounts for 18-20%.The rate of drawing of described Polyurethane glue-line is to be 25% below 5 tons, is 40% more than the 10-30 ton.Described Polyurethane glue-line is of a size of when the load below 5 tons: length is 2-15 rice, and width is 4-15 centimetre, and the Polyurethane glue-line is of a size of when the load of 10-20 ton: length is 10-25 rice, and width is 15-40 centimetre.The time of cooling off in the described step 4 is 24 hours.
The present invention has following beneficial effect: the present invention adopts the Polyurethane glue-line as wearing layer at suspender belt, the Polyurethane glue-line has advantages such as wear-resisting and anti-cutting, it can prevent effectively that the material that hangs can not damage suspender belt in the process of lifting, improve the intensity of suspender belt, the not generation that can cause the accident owing to the damage of suspender belt, and it is aging to prevent effectively that suspender belt from occurring, and reduces labor intensity effectively simultaneously.
Description of drawings
