Problems solved by technology

[0005] 现有技术中,国内外专利都主要集中在保温连接件的外形结构的设计和具体的使用方法上,比如CN202248370U、CN204983189U、CN204715667U、CN203924408U、CN202359664U、CN201924463U、CN202644775U、CN202831363U、CN203878809U、US4829733、US5519973、 In US5671574, US6116836, and US7266931 patents, however, there is little reference to the performance optimization of the key connector core, especially the optimization of mechanical properties.
In addition, some patents have developed connectors with thermoplastic resin as the matrix resin (US5673525, US5987834, US6263638), but based on the disadvantages of the thermoplastic resin itself, it is difficult for the prepared connectors to achieve physical properties close to those of steel bars

Embodiment approach

[0045] According to one embodiment, the present invention relates to a composite material, including a cured product of a resin composition and a reinforcing fiber material. The reinforcing fiber material is in the cured product of the resin composition.

[0046] Raw material consumption also can be controlled according to the scheme of the present invention. In order to further realize the reasonable mutual matching among the various components and make the performance of the composite material better, the dosage is more optimal: by weight, the reinforcing fiber material in the final product is 70-80% and the resin composition is 20-30%. For example, the reinforcing fiber material can also be selected from 71%, 72%, 73%, 74%, 75%, 78%, 80% and so on. The amount of the resin composition can also be selected from 21%, 22%, 24%, 26%, 28%, 30% and so on.

[0047] It is worth noting that one key point of the solution of the present invention is to use a specific thermosetting re...

Embodiment 1

[0126] The preparation method of the composite material is as follows, and the raw materials are all in parts by weight:

[0127] 1) Pass the glass fiber yarn (4800Tex) through the creel, the glue dipping tank, the preforming mold, and finally pass through the thermoforming mold, pass the upper and lower layers of polyester surface mat through the felt guide, the preforming mold, and import Arriving and finally passing through the thermoforming mold, adjusting the count of the fiber yarn so that the glass fiber content of the final product is 80%, and the content of the resin composition in the final product is 20%;

[0128] 2) The configuration of the resin composition is carried out according to the following components: 100 parts by weight of epoxy acrylic resin, 1.0 parts by weight of a composite release agent with a pH value of 6.0, and 15 parts by weight of other auxiliary agents (comprising initiator TBPO / TBPB composite 3 parts by weight, 5 parts by weight of talcum pow...

Embodiment 2

[0133] Other operating steps are basically the same as in Example 1, except that the composite release agent consists of: 80 parts by weight of n-heptanol, methyl methacrylate-methacrylic acid-butyl methacrylate block copolymer (three kinds of The molar ratio of monomer units is: methyl methacrylate: methacrylic acid: butyl methacrylate = 2:1:1.5, number average molecular weight 35000) 22 parts by weight, phosphorylated n-decyl alcohol 3 parts by weight. The pH value of the composite release agent was tested to be 6.6, and the fraction in the resin composition was 1.2 parts by weight. The surface of the sample is always smooth during the production process, without cracks, slag and missing corners, indicating that the release agent has a good effect.

Abstract

The invention relates to a composite material, a preparation method and application thereof, a thermal insulating wall connecting piece and a rod material. The composite material provided by the invention is prepared from a cured resin composition and a reinforced fiber material, wherein the resin composition is prepared from a thermosetting resin matrix, a releasing agent with a pH value of 6.0-7.0 and other optional accessory ingredients.

Description

technical field [0001] The invention relates to the field of preparation of polymer-based composite materials, in particular to a composite material and its preparation method and application, a rod for a thermal insulation wall connector and a thermal insulation wall connector. Background technique [0002] With the continuous innovation and development of the construction market, new building energy-saving wall materials have become the main wall materials for the country's development and promotion. The heat insulation material is placed in the hollow part of the wall, and various heat insulation materials are put in the air, which is a heat insulation material sandwich insulation system. Compared with the single-material exterior wall, the structure of the wall is reasonable and has a higher thermal insulation coefficient, which can better play the role of thermal insulation materials. At the same time, under the premise of meeting the load-bearing requirements, the bri...
