Problems solved by technology

[0007] Through the ordinary humidification method, the balanced water content of the product can be improved to a certain extent, but it is still at a low level. At the same time, this simple humidification method will change with the temperature and relative humidity of the environment, especially in In an environment with high temperature and low relative humidity, the equilibrium moisture content of latex fiberboard will decrease rapidly, making the product prone to breakage and bursting during processing. The impact of environmental factors on product performance is very obvious

Embodiment 1

[0018] 1. Based on the total mass fraction of 100%, add 3.5kg of industrial glycerin (industrial pure), 3kg of zinc chloride (industrial pure), 3.5kg of carboxylated styrene-butadiene latex (50% solid content) and 990kg of water into a container In a plastic tank of 1 ton of liquid, mix and stir evenly to obtain a water-retaining treatment agent for latex fiberboard.

[0019] 2. Under the conditions of sizing temperature of 70°C and sizing pressure of 0.1MPa, apply the above-mentioned latex fiberboard water retention treatment agent on the surface of the latex fiberboard by surface sizing, so that the latex fiberboard water retention treatment agent can penetrate evenly And stay on latex fibreboard.

[0020] 3. Take 10 samples from the 1.25mm latex fiberboard treated with the latex fiberboard water-retaining treatment agent prepared in this example, detect the on-site moisture content of 5 samples, and place the other 5 samples for 48 hours for balance treatment.

[0021] 4. ...

Embodiment 2

[0035] 1. According to the total mass fraction of 100%, add 7kg of industrial glycerin (industrial pure), 6kg of zinc chloride (industrial pure), 7kg of carboxylated styrene-butadiene latex (solid content is 50%) and 980kg of water in turn into a container that can hold 1 ton In a liquid glue tank, mix and stir evenly to obtain a water-retaining treatment agent for latex fiberboard.

Abstract

The invention discloses a water-retention treating agent for latex fiber boards, a preparation process of the water-retention treating agent and a water-retention method. The water-retention treating agent for latex fiber boards is characterized by comprising, by the total mass fraction of 100%, 0.35-0.70% of a moisture absorbent, 0.30-0.60% of a deliquescing agent, 0.35-0.70% of an adhesive and 98.0-99.0% of water. The water-retention treating agent for latex fiber boards can permeate latex fiber boards effectively under high temperature conditions and under the action of pressure, so that moisture of latex fiber boards can be increased, and even if the environment humidity changes, the balanced moisture of latex fiber boards can also be in the normal state and is not changed obviously with environments. By the aid of the water-retention treating agent for latex fiber boards, 10.0% of the long fiber usage amount can be reduced, simultaneously, physical properties of materials are not reduced, and overall indicators of products can meet product quality requirements and can meet machining performance requirements and usage performance requirements of products, so that costs are reduced, and benefit can be increased.

Description

Technical field: [0001] The invention relates to a water retention treatment agent, in particular to a water retention treatment agent for latex fiberboard and a preparation method thereof. Background technique: [0002] Latex fiberboard refers to the inner sole material that contains natural plant fibers, synthetic fibers and polymer materials, and is used in the shoe industry after special processing technology. It has the characteristics of flexibility, elasticity, air permeability, wear resistance, and durability. It can meet the requirements of foot comfort, sanitation, modern hot-melt bonding and other shoe-making technologies. As a special fiberboard material, latex fiberboard is a shoemaking material developed to replace leather, borrowing non-woven fabric and recycled leather technology, and improving its performance. In 1953, the American Texon Company developed Texon products. In 1986, the first machine-made latex fiberboard production line with an annual produc...
