Technical Field

The present invention relates to a lightweight foaming agent.

Background

The foaming agent is a substance for forming pores in a target substance and can be classified into a chemical foaming agent, a physical foaming agent and a surfactant. Chemical blowing agents are those compounds which decompose upon heating to release gases such as carbon dioxide and nitrogen and form pores in the polymer composition; physical blowing agents are those in which the foam cells are formed by a change in the physical form of a substance, i.e., by expansion of a compressed gas, volatilization of a liquid, or dissolution of a solid; the foaming agents have higher surface activity, can effectively reduce the surface tension of liquid, are arranged on the surface of a liquid film in an electric double-layer mode to surround air to form bubbles, and then form foam by single bubbles.

The existing chemical foaming agent has heavy weight and high cost after being used, and cannot be used in some environments with light weight requirements.

Disclosure of Invention

The invention aims to provide a lightweight foaming agent which is light in weight, low in cost and wide in application range.

In order to solve the technical problems, the invention provides a lightweight foaming agent which comprises the following components in parts by weight: 100 portions of crude rubber and 150 portions of carbon black: 120-130 parts of zinc oxide: 6-9 parts of polyether modified silicone oil: 1-3 parts of light calcium carbonate: 40-60 parts of cocoyl diethanol amine: 60-80 parts of polyethylene glycol: 1-3 parts of calcium oxide: 1-3 parts of a vulcanization system: 3.5-5 parts of pentafluoropropane: 3-4 parts of a nucleating agent: 0.5 to 1.0 portion.

Further, the paint comprises the following components in parts by weight: 135 parts of raw rubber, carbon black: 125 parts, zinc oxide: 7 parts of polyether modified silicone oil: 2 parts of light calcium carbonate: 49 parts, cocoyl diethanol amide: 68 parts of polyethylene glycol: 2 parts, calcium oxide: 2 parts of a vulcanization system: 3.9 parts, pentafluoropropane: 3.5 parts, nucleating agent: 0.7 part.

The invention has the beneficial effects that:

the product prepared by the invention can reduce weight and cost, meets the requirements of light weight, energy conservation and consumption reduction, and accords with the development of times.
