Embodiment 1

[0012] Example 1: First, put 1200kg of polyether polyol in a stainless steel reactor and heat it to 80°C for 3 hours, then lower the temperature to 40°C, add 80g of dibutyltin dilaurate and 300g of ethanolamine to react for 2.5 hours, and during the reaction process Gradually heat to 95°C (after 2.5 hours of reaction, the temperature is 95°C), then add 550kg of polymethylene polyphenyl polyisocyanate, add 650kg of diphenylmethane diisocyanate after 2.5 hours of heat preservation reaction, and pump out after 6 hours of heat preservation reaction To the high-speed mixing tank, finally add the auxiliary material dimethyl carbonate 1600kg and stir for 1 hour to produce the finished product. Promptly make the regenerated sponge glue of the present invention environmental protection, adhesive force strong.

Embodiment 2

[0013] Example 2: First, put 1120kg of polyether polyol in a stainless steel reactor and heat it to 76°C for 2.7 hours, then lower the temperature to 37°C, add 73g of dibutyltin dilaurate and 305g of ethanolamine to react for 2 hours, and during the reaction process Gradually heated to 92°C (98°C after 2 hours of reaction), then added 590kg of polymethylene polyphenyl polyisocyanate, added 690kg of diphenylmethane diisocyanate after 2.2 hours of heat preservation reaction, and pumped out after 6.3 hours of heat preservation reaction. To the high-speed mixing tank, finally add the auxiliary material dimethyl carbonate 1680kg and stir for 85min to produce the finished product. Promptly make the regenerated sponge glue of the present invention environmental protection, adhesive force strong.

Embodiment 3

[0014] Embodiment 3: first put polyether polyol: 1248kg in stainless steel reactor and heat for 3.3 hours to 83 ℃, then cool down to 43 ℃, add dibutyltin dilaurate 86g and ethanolamine 294g to react for 3 hours, and in the reaction During the process, gradually heat to 98°C (the temperature is 98°C after 3 hours of reaction), then add 510kg of polymethylene polyphenyl polyisocyanate, add 600kg of diphenylmethane diisocyanate after 2.8 hours of heat preservation reaction, and then add 600kg of diphenylmethane diisocyanate after 5.7 hours of heat preservation reaction Pump it into a high-speed mixing tank, and finally add 1520 kg of auxiliary material dimethyl carbonate and stir for 50 minutes to produce a finished product. Promptly make the regenerated sponge glue of the present invention environmental protection, adhesive force strong.

Abstract

The invention discloses a regenerative sponge glue which is prepared from the following raw materials in parts by weight: 110-125 parts of polyether polyol, 0.007-0.009 part of dibutyltin dilaurate, 0.029-0.031 part of ethanol amine, 50-60 parts of polymethylene polyphenyl polyisocyanate, 60-70 parts of diphenyl methane diisocyanate and 150-170 parts of auxiliary material. The regenerative sponge glue provided by the invention is high in degree of adhesion, has the characteristics of elasticity, good durability, high curing speed, low cost, strong tension, and no three-waste emission during production of products, does not contain benzene homologs and derivates, and is a latest-generation environment-friendly strong regenerative sponge glue. After sponge waste leftovers are recovered and refused, the generated new sponge is capable of ensuring original softness, and free from causing gelling and hardening on an adhering point, so that the regenerative sponge can be suitable for the fields such as furniture, automotive trims, sofas and the like with high requirement on softness of the sponge.

Description

technical field [0001] The invention relates to the field of sponge recovery and reuse, in particular to a regenerated sponge glue. Background technique [0002] Sponge is soft in texture, afraid of heat, and easy to burn. It is a plastic product produced by gelling reaction with polyurethane plus toluene diisocyanate (TDI) or diphenylmethane diisocyanate (MDI). According to the size of the inner bubbles, it can reflect It can be produced in various densities, and can be molded into various shapes according to needs. It is widely used in various industries, mainly used in shockproof, heat preservation, material filling, children's toys and other fields. Due to the large demand for sponges in the market, some sponge factories currently have a large amount of sponge scraps and scraps left after sponge processing and utilization, which are generally discarded as waste or directly incinerated, resulting in a great waste of resources and environmental pollution. Facing the huge ...
