Chloroprene-based latex products, and methods for manufacturing chloroprene-based latex products

Abstract

This invention provides a chloroprene-based latex product that can reduce the generation of aggregates during storage and / or transportation, which was difficult with conventional chloroprene-based latex products. [Solution] According to the present invention, a chloroprene latex product is provided, comprising a container and chloroprene latex filled in the container, wherein at least a portion of the inner surface of the container is made of resin, and the amount of chloroprene latex filled is 90 to 100% of the maximum filling amount of the container.

Claims

1. A container and a chloroprene-based latex filled in the container, At least a portion of the inner surface of the container is made of resin. A chloroprene latex product in which the amount of chloroprene latex filled is 90 to 100% of the maximum filling amount of the container.

2. The chloroprene-based latex product according to claim 1, wherein the container is a blow-molded container and the resin comprises high-density polyethylene.

3. The chloroprene-based latex product according to claim 1 or claim 2, further comprising an outer frame for housing the container.

4. The container is equipped with a filling port and a cap capable of sealing the filling port. The filling port is provided on the upper surface of the container. The chloroprene-based latex product according to claim 1 or claim 2, wherein the cap is removable and gas can be released from the container with the cap attached to the filling port.

5. The chloroprene latex product according to claim 1 or claim 2, wherein, after being stored at 23°C for 3 days, the chloroprene latex is removed from the container and filtered through an 80-mesh wire mesh, and the mass of solids remaining on the wire mesh is 0.0300% by mass or less relative to 100% by mass of the chloroprene latex.

6. The chloroprene latex product according to claim 1 or claim 2, wherein the chloroprene latex has a solid content concentration of 35.0 to 70.0% by mass.

7. The chloroprene-based latex product according to claim 1 or claim 2, wherein the chloroprene-based latex has a viscosity of 5 to 1500 mPa·s as measured by a B-type viscometer at 23°C.

8. A method for manufacturing chloroprene latex products, This includes a filling process for filling containers with chloroprene-based latex products. In the filling process, chloroprene latex is filled to 90-100% of the maximum filling capacity of the container. The container has an inner surface that is made of resin, at least a portion of it. A method for manufacturing chloroprene latex products.
