Problems solved by technology

Nylon fiber is easy to absorb moisture. After absorbing moisture, the weight of the rope will increase, and the strength will decrease accordingly, and the wear resistance will decrease. After the rope absorbs moisture and freezes, it loses its original softness and is difficult to operate

preparation example Construction

[0025] A preparation method of an outdoor sports rope waterproof coating agent is realized through the following steps:

[0026] 1) Weigh the reactants in the components according to the volume content, add 1 / 2 emulsifier and 1 / 2 initiator into 1 / 2 ion water, and form emulsified aqueous solution system A in the colloid mill;

[0027] 2) Mix acrylate and acrylic acid monomers according to the volume ratio, slowly add to the above emulsifier system A in the colloid mill, and emulsify for 40 minutes to form prepolymer emulsion B;

[0028] 3) Put the remaining emulsifier, initiator, ionized water and 1 / 4 of the prepolymer emulsion B into a three-necked flask with a stirrer and a condenser, and heat it to 80-85°C in a water bath;

[0029] 4) Drop the remaining prepolymer emulsion B into the flask within 2-3 hours, continue to react for 2-3 hours after the dropwise addition, cool down and discharge to obtain a homogeneous emulsified dispersion, which is the waterproof coating agent....

Abstract

The invention discloses a preparation and use method of a waterproof coating agent of an outdoor exercise rope and relates to the field of a rope net. The waterproof coating agent is formed by pre-polymerizing and polymerizing acrylate and fluorine-containing acrylic monomer in an initiator and emulsifier aqueous solution system. The preparation technology and the use method are relatively simple; the cost of the raw materials is low; the raw materials are simple and are easily acquired; the water absorption not more than 5% is required on the basis of the requirement for waterproof property according to a performance index of the outdoor exercise rope; after the invention is applied, the test is performed according to a waterproof test method for Power Rope on the basis of international mountain climbing union standard UIAA101; the water absorption of the rope after being settled is 0-4%, meets the standard requirement and meets the requirement for the waterproof property of the rope in outdoor exercise.

Description

technical field [0001] The invention relates to the field of rope nets, in particular to a method for preparing and using a waterproof coating agent for outdoor sports ropes. Background technique [0002] The safety ropes used in outdoor sports such as high-altitude hiking, iceberg travel, and steep wall trekking are mostly made of nylon fibers. Nylon fiber is easy to absorb moisture. After absorbing moisture, the weight of the rope will increase, and the strength will decrease accordingly, and the wear resistance will decrease. Therefore, it is necessary to carry out waterproof finishing to this type of outdoor sports rope, so as to improve the safety and protection performance of the rope to outdoor sports personnel. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a method for preparing and using a waterproof coating agent for outdoor sports ropes. The waterproof performance of the outdoor rope...
