Problems solved by technology

[0003] During the operation process of sewing uppers of rubber shoes, due to the certain elasticity of polyurethane foam, there will be deviations in the positioning and sewing of the composite upper cloth and the back upper of rubber shoes, which will affect the appearance quality and production efficiency of the rubber shoes heel
[0004] In order to improve the production efficiency, improve the appearance quality and accurate positioning of the rubber shoe top bag sponge, it is necessary to position and bond the composite top cloth to the corresponding part of the back side before sewing, so a sponge adhesive is needed for Overcome the quality problems existing in the operation of package system port

Abstract

The invention discloses an adhesive for black rubber shoe topline sponges as well as a preparation method and an application of the adhesive. The adhesive is prepared from natural rubber, sulfur, a vulcanizing accelerator, a vulcanizing activator, rosin and 120# gasoline as raw preparation materials. The crosslinking stress of the adhesive is improved, the adhesion stress is higher than compression resilience force of polyurethane foamed plastics and bending bounce of composite topline cloth, furthermore, the crosslinking forming speed of rubber cement is increased, the composite topline cloth is tightly fixed on an upper lining, and by means of a method for adhering covering sponges to the topline cloth and a heel part in advance, the problem of non-uniform appearance quality of a rear topline of a rubber shoe due to inaccurate positioning of the topline cloth and non-uniform press-fit tightness of the covering sponges in a sewing process of the topline cloth and the heel part is solved and the sewing speed and the production efficiency of the covering sponges for an upper topline can be greatly increased. With the adoption of the adhesive, the reworking rate of the covering sponges for the rubber shoe topline is reduced to 0 from original 5%, and the production efficiency is improved by 15%.

Description

technical field [0001] The invention relates to the field of preparation of adhesive materials, in particular to a black rubber shoe sponge adhesive and its preparation method and application. Background technique [0002] In the style design process of rubber shoes, in order to achieve the problem of wearing the rubber shoes on the heel, keeping warm and preventing cold, a type of rubber shoes adopts black composite cloth at the heel opening (generally polyester filament warp-knitted mesh fabric / polyurethane sponge composite material)” The lining is a certain thickness of polyurethane foam (conventional pattern, the thickness of polyurethane foam is about 15mm, and the specific gravity is about 0.3). This method of sewing uppers is commonly known as sewing bags. [0003] During the operation process of sewing uppers of rubber shoes, due to the certain elasticity of polyurethane foam, the positioning and sewing of the composite upper cloth and the back upper of rubber shoes ...
