preparation example Construction

[0033] The present invention provides a kind of preparation method of polyurethane wall tile, and this preparation method uses the composition material of polyurethane wall tile of the present invention as raw material, comprises:

[0034] Mix 100 parts of polyether polyol, 2 to 5 parts of crosslinking agent, 1 to 2 parts of amine catalyst, 3 to 5 parts of stabilizer, 30 to 50 parts of flame retardant and 10 to 30 parts of blowing agent to obtain Group A Minute;

[0035] Add component A and polyisocyanate to a high-pressure injection molding machine in a weight ratio of 10:12 to 10:15 to obtain a mixed material, and the temperature of the mixed material is 20 to 40 degrees Celsius;

[0036] The mixed material is poured into a mold, and the mixed material is solidified and formed by one-step foaming to obtain a polyurethane wall tile. The temperature in the mold is 30 to 60 degrees Celsius.

[0037] Concretely, in practical application, in order to make the appearance of the p...

Embodiment 1

[0043] In this embodiment, the polyurethane wall tile can include component A and component B, in parts by weight, component A is 10 parts, and component B is 15 parts;

[0044] Among them, component A may include 70 parts by weight of polyether polyol GR-635C, 30 parts of polyether polyol GE-210, 5 parts of 1,4-butanediol, 2 parts of triethylene Diamine catalyst, 5 parts of organosilicon surfactant, 50 parts of dimethyl methylphosphonate and 10 parts of dichloro-fluoroethane;

[0045] The B component may be a polyisocyanate.

[0046] Using the above-mentioned component materials in parts by weight as raw materials, the specific preparation method can be as follows:

[0047] After the polyether polyol GR-635C and polyether polyol GE-210 are mixed evenly, mix the uniformly mixed polyether polyol, crosslinking agent, amine catalyst, stabilizer, flame retardant and blowing agent to obtain A components;

[0048] Add component A and polyisocyanate to a high-pressure injection mo...

Embodiment 2

[0056] In the present embodiment, the polyurethane wall tile may include component A and component B, in parts by weight, component A is 10 parts, and component B is 13.5 parts;

[0057] Among them, component A can include 65 parts of polyether polyol GR-635C, 35 parts of polyether polyol GE-210, 3.5 parts of 1,4-butanediol, 1.5 parts of triethylene Diamine type catalyst, 4 parts of silicone surfactants, 40 parts of dimethyl methylphosphonate and 20 parts of dichlorofluoroethane;

[0058] The B component may be a polyisocyanate.

[0059] The preparation method of polyurethane wall tiles in this example is the same as the preparation method of polyurethane wall tiles in Example 1 except that the parts by weight of each component are different, and will not be repeated here.

[0060] Further, in order to understand the performance of the polyurethane wall tile in this embodiment, a performance test can be performed on the polyurethane wall tile, and the specific test results ar...

Description

technical field [0001] The invention relates to the field of building materials, in particular to a polyurethane wall tile and a preparation method thereof. Background technique [0002] At present, the wall tiles suitable for decoration and design mainly include marble, ceramic tiles and other products. Among them, marble has been widely attracted and widely used due to its beautiful appearance and durability. However, marble also has some shortcomings such as easy staining, low stain resistance, regular maintenance, low radiation, bulky, fragile, non-slip, water absorption, and high cost, so it is difficult to meet people's special needs. [0003] As a structural PU foam plastic, also known as imitation wood, polyurethane rigid foam is currently recognized as the most ideal building energy-saving insulation material at home and abroad. There are two main reasons: on the one hand, the PU rigid foam has good toughness and high strength. , dense and tough crust, simple moldi...
