Embodiment 1

[0021] The invention provides a method for preparing a release agent for laminated tubes, comprising the following steps:

[0022] 1), oily asphalt and floor wax are weighed respectively according to the ratio of 1:10 according to the mass ratio of asphalt and floor wax;

[0023] 2) Heat the weighed floor wax in an oven at 120°C for 2-3 hours to melt the floor wax;

[0024] 3), heat the weighed asphalt in an enamel pot to melt the floor wax;

[0025] 4) Stir the melted floor wax and asphalt evenly, and get the required laminate tube release agent after cooling, which can be applied and used.

[0026] The release agent for laminated pipes of the present invention has strong weather resistance and large modulus of elasticity of the oily asphalt, changes from solid to liquid as the temperature rises, exists in solid state at room temperature, and has heat resistance. Floor wax is a waxy product, easy to form a film, has strong adhesion on the surface of objects, and protects th...

Embodiment 2

[0030] The invention provides a method for preparing a release agent for laminated tubes, comprising the following steps:

[0031] 1), oily asphalt and floor wax are weighed asphalt and floor wax according to the ratio of 1:8 according to the mass ratio;

[0032] 2) Heat the weighed floor wax in an oven at 120°C for 2-3 hours to melt the floor wax;

[0033] 3), heat the weighed asphalt in an enamel pot to melt the floor wax;

[0034] 4) Stir the melted floor wax and asphalt evenly, and get the required laminate tube release agent after cooling, which can be applied and used.

Embodiment 3

[0036] The invention provides a method for preparing a release agent for laminated tubes, comprising the following steps:

[0037] 1), oily asphalt and floor wax are weighed asphalt and floor wax respectively according to the ratio of 1:12 according to mass ratio;

[0038] 2) Heat the weighed floor wax in an oven at 120°C for 2-3 hours to melt the floor wax;

[0039] 3), heat the weighed asphalt in an enamel pot to melt the floor wax;

[0040] 4) Stir the melted floor wax and asphalt evenly, and get the required laminate tube release agent after cooling, which can be applied and used.

Abstract

The invention discloses a method for preparing a laminated tube release agent. The method comprises the following steps: (1) respectively weighing asphalt and floor wax according to a ratio of 1:(8-12); (2) heating the weighed floor wax, so that the floor wax is melted; (3) heating the weighed asphalt, so that the asphalt is melted; and (4) uniformly stirring the melted floor wax and asphalt, and cooling, thereby obtaining the needed laminated tube release agent. The preparation method is simple in preparation process, is used in a coating mode and is convenient to operate. Moreover, the prepared laminated tube release agent has short drying time, the molding time is not influenced, and the mold is easily infiltrated to form a continuous film layer, so that the demolding property is excellent.

Description

Technical field: [0001] The invention relates to the field of release agent manufacturing, in particular to a method for preparing a release agent for laminated tubes. Background technique: [0002] The laminated pipe product is a tubular product that is continuously wound with semi-cured sheet-shaped gummed paper and cloth on an iron mold, and then solidified after high temperature. After molding, the product is separated from the mold. In order to remove the cured product from the mold smoothly, it is necessary to apply a release agent on the working surface of the mold. On the one hand, it can make the surface of the product smooth, and on the other hand, it can protect the mold from damage. The release agent cannot contain any components that affect the final quality of the product or post-molding treatment. Molded parts must be able to demould smoothly and cleanly, and cannot be demolded before curing. In addition, because the product needs to be cured after high temp...
