Abstract

The invention relates to a high-tensile strength sponge and a preparation method thereof. In order to solve the problems that an existing market sponge has low tensile strength and cannot satisfy special requirements, the high-tensile strength sponge disclosed by the invention is prepared from a component A and a component B, wherein the component A includes the following materials in parts by weight: 67-90 parts of polyether polyol DEP (Diethyl Phthalate)-560D, 5-30 parts of polymer polyol POP(Polyolefin Plastomer) 45, 3-5 parts of tensile agent MU100, 0.01-0.03 part of light stabilizer, 2.5-3.3 parts of water, 0.8-1.2 parts of foam stabilizer AK6689, 0.24-0.29 part of amine catalyst A33 and 0.18-0.25 part of tin catalyst T9; the component B includes 34-40 parts of isocyanate. The preparation method of the high-tensile strength sponge comprises the following steps of: adding the materials of the component A to a stirrer for uniformly mixing; adjusting the constant material temperature of the component A to 23 DEG C -27 DEG C; adjusting the rotation speed of the stirrer to 7000r / min; pouring the component B which is pre-heated to 23 DEG C-27 DEG C to the component A for stirring for 8 seconds; pouring the mixture to a pre-mould, observing the foaming condition, and curing for 24 hours after initiating; and testing the performances. The high-tensile strength sponge disclosed by the invention has higher tensile strength than that of the common sponge, and can satisfy the requirements of some special products.

Description

technical field [0001] The invention relates to a sponge and a preparation method thereof, in particular to a sponge with high tensile strength and a preparation method thereof. Background technique [0002] Polyurethane foam, commonly known as sponge, its main raw materials are isocyanate, polyether, polyol, etc., which have been widely used in daily life. However, some high-end products have high requirements on the performance of the sponge, such as the demand for tensile strength. The current general raw material technology is not enough to meet the requirements of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sponge with high tensile strength and its preparation method, which can meet the needs of some special products. [0004] A kind of high-strength tensile sponge of the present invention is formulated according to the following weight and number ratios by A and B two kinds of component...
