Abstract

Provided is a stable polyurethane foam joint filling material. The stable polyurethane foam joint filling material is is prepared from the following raw materials, by weight, 8-11 parts of quartz sands, 3-8 parts of petroleum resins, 8-11 parts of p-phenylenediamine, 5-9 parts of flame tree wood chips, 1-4 parts of betelnut tree wood chips, 4-9 parts of expanded pearl powder, 1-5 parts of modified wollastonite, 7-11 parts of wood fibers, 3-9 parts of gypsum powder, 4-7 parts of non-phthalate plasticizers, 2-7 parts of diatomite, 2-5 parts of polyacrylonitrile-based carbon fibers, 2-7 parts of nanosilicon dioxide, 1-3 parts of auxiliary fire-resistant agents, 4-9 parts of chlorinated paraffin, 30-45 parts of polyurethane and 5-10 parts of foaming agents. The beneficial effects of the joint filling material are that performances are stable, filling and sealing effects are good, the weatherability is good, and the application scope is wide.

Description

A kind of stable polyurethane foam pointing

Technical field

The present invention relates to a kind of stable polyurethane foam pointing.

Background technology

In building construction process, there are some gaps for some reason unavoidably, not only affect attractive in appearance, the quality of building may be reduced simultaneously, therefore during construction by supporting applicator gun or manual jet pipe by pointing construction part, short-term completes shaping, foaming, bonds and seal process.The insufficient strength of the general foam of existing pointing, its cured foam elastomerics of polyurethane foam has the premium propertiess such as resistance toly expand with heat and contract with cold, heat insulation, sound insulation is even fire-retardant, is widely used in building doors and windows side seam, being filled with a sealing of member expansion joint and hole place.Therefore, polyurethane foam sealing material more and more receives an acclaim, but still there are some shortcomings, requires further improvement.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of polyurethane foam pointing, stable performance, is filled with a sealing effective, have good weathering resistance simultaneously, applied widely.

For solving prior art problem, technical scheme provided by the invention is, a kind of stable polyurethane foam pointing, and it is made up of the raw material of following parts by weight:

Quartz sand 8-11 part, petroleum resin 3-8 part, Ursol D 8-11 part, twig and leaf of Royal poinciana wood chip 5-9 part, betelnut tree wood chip 1-4 part, expanded pearlite powder 4-9 part, modified grammite 1-5 part, wood fibre 7-11 part, terra alba 3-9 part, non-phthalic ester plasticizer 4-7 part, diatomite 2-7 part, PAN-based carbon fiber 2-5 part, nano silicon 2-7 part, auxiliary flame retardant 1-3 part, clorafin 4-9 part, urethane 30-45 part, whipping agent 5-10 part.

The invention has the beneficial effects as follows: polyurethane foam pointing of the present invention, stable performance, is filled with a sealing effective, has good weathering resistance simultaneously, applied widely.
