The product produced in the utility model is characterized by excellent mechanical performance, nonabsorbency, corrosion resistance, insulation and long service life, applicable for the fields of railroad sleepers, container wall boards, architectural structural profiles and sports equipments.

Description

The shape product of continuous glass-fiber reinforced hard polyurethane microfoam

Technical field

The utility model relates to a kind of glass-fiber reinforced thermo-setting matrix material.Especially the shape product that relates to a kind of continuous glass-fiber reinforced hard polyurethane microfoam.

Background technology

Urethane foam is one of principal item of polyurethane synthetic material.It is mainly made by organic isocyanate and polyol compound reaction.The variation of different according to used raw material from prescription can be made kinds such as soft, semi-rigid and rigid foam.The rigid foam aspect: density is less is mainly used in lagging material, as the insulation of refrigerator, water-heater and pipeline; The high density polyurethane rigid foam also is described hard polyaminoester microvesicle, has natural timber and can saw to dig and performance such as can follow closely, and can be used for making imitative xyloid artwork and decoration, as picture frame, picture frame and automotive upholstery etc.Advantages such as the rigid urethane foam relative density is little, good heat insulating, moulding are easy are that people are known, but this plastics and other materials such as hardwood, glass reinforced plastic compares, and it is more that intensity difference gets, and limited its range of application.If glass fibre reinforcement is joined in the rigid urethane foam matrix, its intensity can improve 3～4 times.In addition, the length difference of glass fibre then the enhanced effect evident difference is also arranged.The enhancing of chopped strand has some application, can be used as some aggregated(particle) structure spares, as parts such as the ceiling interior trim of the luggage carrier of motor bus, dolly, building wall boards.But its intensity is still lower, can not be applied to some load-bearing structural member.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and the shape product of the continuous glass-fiber reinforced hard polyurethane microfoam of a kind of intensity that can further improve the glass fiber reinforced polyurethane goods and rigidity is provided.

The purpose of this utility model is achieved in that a kind of shape product of continuous glass-fiber reinforced hard polyurethane microfoam, it is a matrix with the hard polyaminoester microvesicle, with the continuous glass-fiber yarn through surface infiltration agent processing is strongthener, and the continuous glass-fiber yarn is unidirectional external phase in the intravital distribution of base.

By exemplar or the finished product that different testing programs is made, the contriver has carried out performance test.From test result analysis, think hard polyaminoester microvesicle body material after the continuous glass-fiber yarn strengthens, mechanical property and thermal characteristics all are improved largely, and can be used as load-bearing structural member and use.Following table is different glass fiber contents, the performance comparison sheet of such material of different densities:

The utility model strengthens the matrix material of hard polyaminoester microvesicle with the form of glass external phase, and on chopped glass fiber enhanced basis, its mechanical property especially tensile strength, flexural strength has by a relatively large margin raising.Thereby be applied to some load-bearing structural member.What deserves to be mentioned is: under the identical situation of extrudate density, glass enhanced urethane foam goods are compared with pure urethane foam, and the cost of material descended on the contrary when mechanical property improved, and cost performance of product is improved.

The product that the utility model obtained except that good mechanical property, also have do not absorb water, characteristics such as corrosion resistant insulation, long service life, and possess the processing characteristics of natural timber, can be applicable to aspects such as railroad sleeper, container wall panel, building structure section bar, sports equipment.

Description of drawings

Fig. 1 is the shape product section structure synoptic diagram of the utility model continuous glass-fiber reinforced hard polyurethane microfoam.

Embodiment

Referring to Fig. 1, the utility model is a kind of shape product of continuous glass-fiber reinforced hard polyurethane microfoam, it is a matrix 1 with the hard polyaminoester microvesicle, be strongthener with the continuous glass-fiber yarn of handling through the surface infiltration agent 2, and the continuous glass-fiber yarn is unidirectional external phase in the intravital distribution of base.

The ratio that described body material and strongthener account for the goods gross weight is: body material 35-60%, strongthener 40-65%.Under the identical situation of polyurethane-base volume density, the content of glass fibre is high more, and then the density of goods is big more, and intensity is high more, but low more to the viscosity requirement of body material, it is big that the difficulty of formulating of recipe also becomes.Through measuring and calculating, when glass fiber content during in 50% left and right sides, the starting material direct expenses of product is lower.

The utility model adopts the anilinomethyl trimethoxy silane coupling agent that glass yarn surface is handled, and the combination at interface is significantly improved, and the enhanced effect obviously improves.

Claims

1. the shape product of a continuous glass-fiber reinforced hard polyurethane microfoam, it is characterized in that it is is matrix (1) with the hard polyaminoester microvesicle, with the continuous glass-fiber yarn (2) through surface infiltration agent processing is strongthener, and the distribution of continuous glass-fiber yarn (2) in matrix (1) is unidirectional external phase.
