Abstract
Present invention is disclosed a kind of high viscosity polyurethane fluid sealant, including polyurethane resin, viscosifier, cross-linking agent, plasticiser, scratching resistant and UV absorbent, described viscosifier are pentalyn, described cross-linking agent is Hydroxypropyl acrylate, described plasticiser is dioctyl phthalate, described scratching resistant is palm wax, and described UV absorbent is single benzoic acid resorcinol.This product uses polyurethane resin and viscosifier, cross-linking agent, plasticiser, scratching resistant and five kinds of additives of UV absorbent to prepare, and the product viscosity prepared is strong, quality good, easy to process, mar-resistance good, ageing-resistant, Anti-tarnishing, using effect are good.
Description
Technical field
The present invention relates to encapsulant, be specifically related to a kind of high viscosity polyurethane fluid sealant.
Background technology
Encapsulant refers to bear the material that seam displacement embeds in building joint to reach airtight, watertight purpose and is referred to as encapsulant.Sealing member material has metal material (aluminum, lead, indium, rustless steel etc.), also there are nonmetallic materials (rubber, plastics, pottery, graphite etc.), a composite (such as rubber-asbestos board, aerogel blanket-polyurethane), but using most is heat-resistant powder filler material.Polyurethane resin is widely used as a kind of main encapsulant raw material, but due to more difficult in polyurethane processing itself, making product quality relatively general, adhesive strength cannot meet use demand instantly so that adhesive effect in use is poor.And the non-oxidizability of polyurethane own is general, the most aging after long-time use, there is complexion changed so that using effect is deteriorated.
Summary of the invention
It is an object of the invention to provide a kind of employing polyurethane resin and viscosifier, cross-linking agent, plasticiser, scratching resistant and five kinds of additives of UV absorbent prepare, the high viscosity polyurethane fluid sealant that product viscosity is strong, quality good, easy to process, mar-resistance good, ageing-resistant, Anti-tarnishing, using effect are good prepared.
nullThe technical scheme is that，A kind of high viscosity polyurethane fluid sealant，Including polyurethane resin、Viscosifier、Cross-linking agent、Plasticiser、Scratching resistant and UV absorbent，Described viscosifier are pentalyn，Described cross-linking agent is Hydroxypropyl acrylate，Described plasticiser is dioctyl phthalate，Described scratching resistant is palm wax，Described UV absorbent is single benzoic acid resorcinol，Percentage by weight shared by the described each composition of high viscosity polyurethane fluid sealant is respectively as follows: described polyurethane resin and accounts for 84.7%-89.2%，Described pentalyn accounts for 2.6%-3.5%，Described Hydroxypropyl acrylate accounts for 1.9%-2.8%，Described dioctyl phthalate accounts for 2.2%-3.1%，Described palm wax accounts for 2.7%-3.6%，Described single benzoic acid resorcinol accounts for 1.4%-2.3%.
In a preferred embodiment of the present invention, shared by the described each composition of high viscosity polyurethane fluid sealant, percentage by weight is particularly as follows: described polyurethane resin accounts for 88.6%, described pentalyn accounts for 2.7%, described Hydroxypropyl acrylate accounts for 2.1%, described dioctyl phthalate accounts for 2.3%, described palm wax accounts for 2.8%, and described single benzoic acid resorcinol accounts for 1.5%.
In a preferred embodiment of the present invention, shared by the described each composition of high viscosity polyurethane fluid sealant, percentage by weight is particularly as follows: described polyurethane resin accounts for 85.3%, described pentalyn accounts for 3.4%, described Hydroxypropyl acrylate accounts for 2.7%, described dioctyl phthalate accounts for 2.9%, described palm wax accounts for 3.5%, and described single benzoic acid resorcinol accounts for 2.2%.
Of the present invention is a kind of high viscosity polyurethane fluid sealant, this product uses polyurethane resin and viscosifier, cross-linking agent, plasticiser, scratching resistant and five kinds of additives of UV absorbent to prepare, and the product viscosity prepared is strong, quality good, easy to process, mar-resistance good, ageing-resistant, Anti-tarnishing, using effect are good.
Detailed description of the invention
Below presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
nullOf the present invention is a kind of high viscosity polyurethane fluid sealant，Including polyurethane resin、Viscosifier、Cross-linking agent、Plasticiser、Scratching resistant and UV absorbent，Described viscosifier are pentalyn，Described cross-linking agent is Hydroxypropyl acrylate，Described plasticiser is dioctyl phthalate，Described scratching resistant is palm wax，Described UV absorbent is single benzoic acid resorcinol，Percentage by weight shared by the described each composition of high viscosity polyurethane fluid sealant is respectively as follows: described polyurethane resin and accounts for 84.7%-89.2%，Described pentalyn accounts for 2.6%-3.5%，Described Hydroxypropyl acrylate accounts for 1.9%-2.8%，Described dioctyl phthalate accounts for 2.2%-3.1%，Described palm wax accounts for 2.7%-3.6%，Described single benzoic acid resorcinol accounts for 1.4%-2.3%.
Further, shared by the described each composition of high viscosity polyurethane fluid sealant, percentage by weight is particularly as follows: described polyurethane resin accounts for 88.6%, described pentalyn accounts for 2.7%, described Hydroxypropyl acrylate accounts for 2.1%, described dioctyl phthalate accounts for 2.3%, described palm wax accounts for 2.8%, and described single benzoic acid resorcinol accounts for 1.5%.
Further, shared by the described each composition of high viscosity polyurethane fluid sealant, percentage by weight is particularly as follows: described polyurethane resin accounts for 85.3%, described pentalyn accounts for 3.4%, described Hydroxypropyl acrylate accounts for 2.7%, described dioctyl phthalate accounts for 2.9%, described palm wax accounts for 3.5%, and described single benzoic acid resorcinol accounts for 2.2%.
Proportioning is carried out so that the properties of product height obtained differs by each composition Different Weight percentage ratio.
High viscosity polyurethane fluid sealant of the present invention is when producing, by polyurethane resin is processed into molten condition, performance according to each additive melts at polyurethane resin and is front and back added, and afterwards by injection mo(u)lding, forms high viscosity polyurethane fluid sealant finished product.
Of the present invention is a kind of high viscosity polyurethane fluid sealant, this product uses polyurethane resin and viscosifier, cross-linking agent, plasticiser, scratching resistant and five kinds of additives of UV absorbent to prepare, and the product viscosity prepared is strong, quality good, easy to process, mar-resistance good, ageing-resistant, Anti-tarnishing, using effect are good.
The foregoing is only the detailed description of the invention of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope that disclosed herein; the change can expected without creative work or replacement, all should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims are limited.
